+%% ****** Start of file README ****** %
+%%
+%% This file is part of the APS files in the REVTeX 4 distribution.
+%% Version 4.2c of REVTeX, January, 2019.
+%%
+%% Copyright (c) 1999-2019 American Physical Society.
+%%
+
+Last updated 18 January 2019
+
+This file describes the contents of this distribution of REVTeX 4.2,
+version 4.2c. The definitive source of information about REVTeX 4
+is the APS web page http://journals.aps.org/revtex/.
+
+User queries should be directed to revtex@aps.org.
+
+Manifest
+--------
+All files in this release are contained within a second zip file within the
+main zip file called revtex4-2-tds.zip. This contains all of the REVTeX 4.2
+files in the TeX Directory Structure (TDS) layout used with most current TeX
+distributions. Install REVTeX 4.2 by unzipping the files in the appropriate
+place (usually the texmf-local directory of your local TeX installation) and
+running texhash or the equivalent command to index the files. Please consult your
+TeX distribution's guide for installing new packages.
+
+NOTE: The only files necessary for running REVTeX 4.2 are those under
+tex/latex/revtex and bibtex/bst/revtex, but it is a good idea to install
+the entire distribution, especially the documentation.

+Not Included
+------------
+The following packages are required by REVTeX but are not
+included in this distribution. Please obtain from CTAN
+(Comprehensive TeX Archive Network), e.g. <http://www.ctan.org/>. Direct
+links to the necessary files can be found at <http://journals.aps.org/revtex/>.
+
+natbib.dtx - Version 8.31a or later; found in latex/contrib/natbib on CTAN
+natbib.ins - LaTeX this to create natbib.sty and natbib
+ documentation from natbib.dtx
+bm.dtx - Bold math style - part of (current!) standard LaTeX2e tools
+bm.sty - generated from bm.dtx by running tools.ins
+textcase.dtx - Found in latex/contrib/textcase on CTAN
+textcase.ins - LaTeX this to generate textcase.sty from textcase.dtx
+url.sty - Found in latex/contrib/misc on CTAN
+
+An up-to-date installation of AMS-LaTeX is also required for certain
+documentclass options. Version 2.0 or higher is needed. It is
+available from <http://www.ams.org/tex/>.
+
+Recommended styles and packages
+--------------------------
+With REVTeX implemented as a native LaTeX2e document class, users can
+take advantage of many of the well-supported LaTeX2e packages available.
+Here are some that are particularly useful and recommended.
+
+longtable.sty for tables running to multiple pages - part of a
+standard LaTeX2e distribution.
+
+hyperref.sty for hyperlinking - should work well with REVTeX 4.2.
+
+graphics.sty and graphicx.sty for figure inclusion - part of LaTeX2e's
+standard distribution.
+
+Credits
+-------
+David Carlisle created the first draft of REVTeX 4; Arthur Ogawa has
+supported the TeX development versions 4.0 and 4.1. Patrick Daly was so kind
+as to incorporate needed changes into natbib and custom-bib. All worked under
+commission from the APS, with the support of AIP, and was coordinated by Mark
+Doyle, APS. Version 4.2 was initially developed by Aptara Corporation under
+the guidance of Mark Doyle, APS, and Brian Goss, AIP. Development of the final
+version of 4.2 was done by Mark Doyle. The APS is the maintainer of REVTeX,
+and all bugs are our responsibility. Please e-mail feedback to revtex@aps.org.
+
+Backwards compatibility
+-----------------------
+The REVTeX 4.2 class file has been named revtex4-2.cls to distinguish it
+from its predecessors. Files prepared under REVTeX 4.0 or 4.1 may need minor
+changes to process under 4.2 and the output may be formatted differently.
+
+LaTeX2e requirements
+--------------------
+REVTeX 4 requires:
+LaTeX2e [1996/06/01],
+natbib [2009/11/07]
+textcase

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+ % This bibliography style file is intended for texts in ENGLISH
+ % This is an author-year citation style bibliography. As such, it is
+ % non-standard LaTeX, and requires a special package file to function properly.
+ % Such a package is natbib.sty by Patrick W. Daly
+ % The form of the \bibitem entries is
+ % \bibitem[Jones et al.(1990)]{key}...
+ % \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
+ % The essential feature is that the label (the part in brackets) consists
+ % of the author names, as they should appear in the citation, with the year
+ % in parentheses following. There must be no space before the opening
+ % parenthesis!
+ % With natbib v5.3, a full list of authors may also follow the year.
+ % In natbib.sty, it is possible to define the type of enclosures that is
+ % really wanted (brackets or parentheses), but in either case, there must
+ % be parentheses in the label.
+ % The \cite command functions as follows:
+ % \citet{key} ==>> Jones et al. (1990)
+ % \citet*{key} ==>> Jones, Baker, and Smith (1990)
+ % \citep{key} ==>> (Jones et al., 1990)
+ % \citep*{key} ==>> (Jones, Baker, and Smith, 1990)
+ % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2)
+ % \citep[e.g.][]{key} ==>> (e.g. Jones et al., 1990)
+ % \citep[e.g.][p. 32]{key} ==>> (e.g. Jones et al., p. 32)
+ % \citeauthor{key} ==>> Jones et al.
+ % \citeauthor*{key} ==>> Jones, Baker, and Smith
+ % \citeyear{key} ==>> 1990

+\section{Introduction}
+
+This is the author's guide to the AIP substyles for \revtex~4.2,
+providing a useful formatting tool
+for \LaTeX\ users submitting papers to journals
+published by the American Institute of Physics.
+This guide is intended as an adjunct to the documentation for \revtex\ itself
+(published by the American Physical Society),
+so information contained therein is not repeated here,
+except as it bears on the specific features of the AIP substyles.
+
+
+\subsection{Prerequisite Documentation}
+
+The following documentation should be considered your first source of information
+on how to prepare your document for use with this format;
+they are to be found within the APS \revtex~4.2 distribution.
+Updated versions of these are maintained at
+the \revtex~4.2 homepage located at \url{http://journals.aps.org/revtex/},
+are also available at the Comprehensive \TeX\ Archive Network (CTAN, see \url{http://www.ctan.org/}),
+and form part of the \TeX Live distribution of \TeX.
+\begin{itemize}
+\item \textit{Author's Guide to \revtex~4.2}
+\item \textit{\revtex~4.2 Command and Options Summary}
+\end{itemize}
+The present guide builds upon these documents, with which you should already be familiar.
+
+The AIP substyles distribution for \revtex~4.2 includes
+a sample document (\file{aipsamp.tex}),
+a good starting point for
+the manuscript you are preparing for submission to an AIP journal.
+
+By using \revtex's \textit{Author's Guide to \revtex~4.2}, you can develop your
+document until it contains all of the content you desire.
+This guide informs you on document class options, commands, and
+markup guidelines specific to AIP journals.
+
+\subsection{Software Requirements}
+
+This guide assumes a working \revtex~4.2 installation including the AIP substyles.
+Please see the installation guide included with the distribution.\cite{Note1}
+
+Please note that the AIP substyles work {\it only} with \revtex~4.2:
+the original \revtex~4.0 release does {\it not} make the AIP substyle available, nor is it compatible with them.
+
+For your computer to run \revtex~4.2 with the AIP substyles, the following are required:
+\begin{itemize}
+\item
+a working installation of \LaTeX\,
+\item
+\revtex~4.2 and all packages it requires,
+\item
+the AIP substyles for \revtex~4.2, and
+\item
+any further \LaTeX\ packages used in your document.
+\end{itemize}
+
+The easiest way to obtain all of the needed software is to install an up-to-date distribution of \TeX,
+like \TeX Live, available on CTAN.
+
+To obtain the most up-to-date version of this software, please see \url{http://publishing.aip.org/authors/preparing-your-manuscript}.
+
+
+\subsection{Submitting to AIP Journals}
+
+Authors preparing a manuscript for submission to
+AIP journals should consult the Information for Contributors for the applicable journal,
+available through links at \url{http://scitation.aip.org/authors}.
+These requirements are not covered systematically in this author's guide;
+you are responsible for understanding the requirements of the particular journal to which
+you will submit your article.
+
+For further information about journal requirements, contact the Editorial
+Office of the appropriate journal. (Follow links at \url{http://scitation.aip.org/authors}.)
+
+\subsection{Contact Information}\label{sec:resources}%
+Any bugs, problems, or inconsistencies concerning the AIP journal substyles
+should be reported to AIP support at \href{mailto:tex@aip.org}{tex@aip.org}.
+Reports should include information on the error and a
+\textit{small} sample document that manifests the problem, if possible.
+(Please don't send large files!)
+
+Feedback concerning \revtex~4.2 itself should be sent, as usual,
+to the American Physical Society at\\ \href{mailto:revtex@aps.org}{revtex@aps.org}.
+
+To determine if the problem you are experiencing belongs to \revtex\ or is specific to the
+AIP substyles, simply remove \texttt{aip} from your document class options and rerun
+your document. If the problem goes away, you may assume that it is due to the AIP substyles;
+if not, it belongs to \revtex.
+
+\section{Sample \LaTeXe\ Document}
+As the \revtex\ documentation makes clear, your document employs a \LaTeXe\ document class
+(specifically \texttt{revtex4-2.cls}), so you should use
+the \LaTeXe\ commands and environments familiar to you with, say, the
+standard article class \texttt{revtex4-2.cls}, and you will be able to
+employ many of the packages you are used to using with \LaTeXe.
+
+Using \texttt{aipsamp.tex} as an example,
+your document will start with the usual \revtex\ \cmd\documentclass\ statement, but with
+a particular document class option \texttt{aip} that specifies the AIP substyle:
+\begin{verbatim}
+\documentclass[aip]{revtex4-2}
+\end{verbatim}
+You will then invoke the \LaTeXe\-compatible packages your document requires, say:
+\begin{verbatim}
+\usepackage{graphicx}%
+\usepackage{dcolumn}%
+\usepackage{bm}%
+\end{verbatim}
+follow up with your document content:
+\begin{verbatim}
+\begin{document}
+...
+\end{verbatim}
+and finish with a statement specifying your Bib\TeX\ database:
+\begin{verbatim}
+\bibliography{aipsamp}
+\end{document}
+\end{verbatim}
+
+The books
+in the bibliography of this guide provide extensive coverage of all topics
+pertaining to preparing documents under \LaTeXe\; they are highly recommended.
+
+\section{\revtex\ Class Options Specific to AIP}
+
+\subsection{Journal Substyle}
+To access particular features of the AIP substyle, you will specify an additional document class option: the journal substyle, e.g.,
+\begin{verbatim}
+\documentclass[aip,jcp]{revtex4-2}
+\end{verbatim}
+in this case, \textit{J. Chem. Phys.}, the default.
+A complete list of AIP journals with the corresponding journal substyle appears in Table~\ref{tab:journals}.
+\begin{table}
+\caption{\label{tab:journals}AIP journal substyles}
+\begin{ruledtabular}
+\begin{tabular}{ll}
+\textbf{Journal} & \textbf{class option} \\
+\itshape AIP Advances &\texttt{adv}\\
+\itshape Appl. Phys. Lett. &\texttt{apl}\\
+\itshape Appl. Phys. Lett. Mater.&\texttt{apm}\\
+\itshape Biomicrofluidics &\texttt{bmf}\\
+\itshape Chaos &\texttt{cha}\\
+\itshape J. Appl. Phys. &\texttt{jap}\\
+\itshape J. Chem. Phys. &\texttt{jcp}\footnotemark[1]\\
+\itshape J. Math. Phys. &\texttt{jmp}\\
+\itshape J. Renewable Sustainable Energy&\texttt{rse}\\
+\itshape Phys. Fluids &\texttt{pof}\\
+\itshape Phys. Plasmas &\texttt{pop}\\
+\itshape Rev. Sci. Instrum.&\texttt{rsi}\\
+\itshape Structural Dynamics &\texttt{sd}\\
+\end{tabular}
+\end{ruledtabular}
+\footnotetext[1]{Default journal substyle.}
+\end{table}
+
+\subsection{Options for Citations and Bibliography}
+The citation style for AIP journals is:
+\begin{itemize}
+\item
+numerical (default style),
+\item
+author-year, and
+\item
+numerical author-year,
+\end{itemize}
+the latter two styles being only allowed for \textit{Chaos} or \textit{J. Math. Phys.}
+
+The familiar numerical citations and numbered bibliography are the default for most journals:
+citations are superscript numbers, and the (numbered) bibliographic entries appear in the order cited.
+
+Author-year citations are only allowed for
+\textit{Chaos} or \textit{J. Math. Phys.}, with citations given in author-and-year format.
+Bibliographic entries are sorted by alphabetical order of first author's surname, then by year.
+
+Numerical author-year citations
+(only allowed for \textit{Chaos} or \textit{J. Math. Phys.})
+are superscript numbers, just like numerical citations,
+but the bibliographic entries are sorted like the author-year entries and are numbered.
+This means that the first citation will not necessarily be~1.
+
+To obtain the numerical style, simply accept the default, or supply a class option of \texttt{numerical}:
+\begin{verbatim}
+\documentclass[aip,numerical]{revtex4-2}
+\end{verbatim}
+For author-year citations for \textit{Chaos} or \textit{J. Math. Phys.},
+you may specify the \texttt{author-year} option:
+\begin{verbatim}
+\documentclass[aip,author-year]{revtex4-2}
+\end{verbatim}
+Each of the above two options are part of standard \revtex.
+
+To obtain numerical author-year citations
+for \textit{Chaos} or \textit{J. Math. Phys.},
+give the author-numerical option:
+\begin{verbatim}
+\documentclass[aip,author-numerical]{revtex4-2}
+\end{verbatim}
+Note that the \texttt{author-numerical} option is not part of standard \revtex\, so use of it
+outside of the AIP substyles may not have any effect.
+
+\subsection{Formatting Options}
+There are two commonly used formats for an article you may write.
+One will comply with the manuscript submission formatting requirements of the editorial office of the journal you are submitting to.
+The other will emulate the format of your article in the published journal itself.
+
+For journal submission, accept the default, or you may specify the \texttt{preprint} option:
+\begin{verbatim}
+\documentclass[aip,preprint]{revtex4-2}
+\end{verbatim}
+To emulate the formatting of the journal, specify the \texttt{reprint} option:
+\begin{verbatim}
+\documentclass[aip,reprint]{revtex4-2}
+\end{verbatim}
+Note that emulation is not by any means complete: the fonts used will differ, and therefore
+the length of the article will not represent an accurate estimate.
+Other details may also differ.
+
+A summary of class options of interest to AIP authors appears in Table~\ref{tab:options}.
+\begin{table}
+\caption{\label{tab:options}Other class options}
+\begin{ruledtabular}
+\begin{tabular}{ll}
+\textbf{Function} & \textbf{class option} \\

+\footnotetext[3]{Only allowed for \textit{Chaos} or \textit{J. Math. Phys.}}%
+\end{table}
+
+\section{Useful \LaTeXe\ Markup}
+\LaTeXe\ markup is the preferred way to structure your file.
+In general, the use of low-level commands like \TeX\ primitives or Plain \TeX\ macros
+is less preferable.
+Please see the \revtex\ User's Guide,\cite{Note2}
+the \LaTeX\ manual,\cite{LaTeXman}
+and the \LaTeXe\ book\cite{Compan}
+for further details.
+
+\subsection{Title and Front Matter}\label{sec:front}
+
+The \revtex\ User's Guide has complete information on using \revtex's special markup for your
+article's title, author list, abstract, and other front matter elements.
+Note that class option \texttt{superscriptaddress} is the default for the AIP substyles,
+as required by all AIP journals.
+
+\subsection{Lead Paragraph}
+One AIP journal, \textit{Chaos}, requires a paragraph of text to precede the first
+\cmd\section\ of the article;
+this is known as a lead paragraph and is formatted boldface.
+To give your article a lead paragraph,
+include a quotation environment ahead of the first \cmd\section\ command:
+\begin{verbatim}
+\documentclass[aip]{revtex4-2}
+\begin{document}
+ \begin{quotation}
+ Here is my lead paragraph!
+ \end{quotation}
+ \section{Introduction}
+...
+\end{verbatim}
+
+The \texttt{quotation} environment functions normally after the first \cmd\section\ command in the document.
+
+\section{Body}
+
+For general information on commands used in the body of the document, see the \revtex\ User's Guide.
+Herein are some features specific to the AIP author.
+
+\subsection{Footnotes}
+
+If you are using numbered citations (numerical or numbered author-year),
+footnotes are by default incorporated into the reference section
+along with your bibliographic entries.
+This automated feature is only effective if you use Bib\TeX\ to prepare your
+bibliography.
+
+Author-year style bibliography does not lend itself to such a treatment,
+so by default footnotes appear in text as is usual.
+However, be advised that, if your article is accepted for publication,
+footnotes may be incorporated into text during the production process.
+
+\section{Citations and References}\label{sec:endnotes}
+
+The preparation of your bibliography ``by hand'' is possible;
+however, if you do so,
+you will be entirely responsible
+for compliance with submission requirements for your bibliographic entries,
+for incorporating any text footnotes into the references,
+and for checking bibliographic entries.
+(In this connection, you may find useful the file \texttt{reftest.tex}, distributed with \revtex.)
+
+There are numerous reasons to use Bib\TeX, not least because it automates the first and second of the above checks.
+
+\subsection{\label{sec:use-bib}Using Bib\protect\TeX}
+
+Refer to the \revtex\ User's Guide, the \LaTeX\ manual, and the Bib\TeX\ manual
+for full information about using Bib\TeX.
+
+When using Bib\TeX\, keep in mind that changing your bibliography style or citation style
+(via the document class options described above) will require you to rerun Bib\TeX.
+The standard litany (using \texttt{aipsamp.tex} as an example) for this is:
+\begin{verbatim}
+> latex aipsamp
+> bibtex aipsamp
+> latex aipsamp
+> latex aipsamp
+\end{verbatim}
+Here, the first invocation of \texttt{latex} has the effect of rewriting the
+\texttt{aipsamp.aux} file,
+and the invocation of \texttt{bibtex} creates a new \texttt{aipsamp.bbl} file.
+The next two runs of \texttt{latex} are then required:
+the first to update the \texttt{aipsamp.aux} file reflecting the new values of your citations
+and the second to employ those citations correctly.
+Be sure to check the end of the \texttt{aipsamp.log} file for any message advising you to
+rerun \texttt{latex}.
+
+\subsection{Multiple References per Citation}
+In an article using numerical citations,
+it is not uncommon to encounter the need for a citation
+that refers to more than one article or other reference.
+To accommodate such a case, \revtex~4.2 implements markup similar to that of the
+\texttt{mcite} package for \LaTeXe.
+
+Let's say that two citation keys \texttt{able} and \texttt{baker}
+need to be combined into a single reference.
+The syntax for the \cmd\cite\ command is:
+\begin{verbatim}
+word\cite{able,*baker} further text
+\end{verbatim}
+When you run Bib\TeX\, the resulting bibliography will contain the two entries, but run together
+as a single numbered reference.
+In the \cmd\cite\ command argument, any cite key that starts with the * character
+signifies that its bibliographic entry is to be joined together with the one preceding it;
+the \texttt{*} may join together any number of entries into a single reference.

+\section{Introduction}
+Articles published in American Physical Society journals are converted to
+an XML file during final journal production. Other formats such
+as PDF are derived directly from the XML, which constitutes the version of record.
+Even before journal production, the APS editorial process can make use
+of the information in a properly prepared manuscript. Information such
+as title, authors, affiliations, etc., can be automatically
+extracted and used to populate our manuscript database. References can
+also be culled, cross-checked for accuracy, and used to create a
+linked version for referees and editors. Moreover, time can be saved
+as referrals can be made electronically rather than by conventional
+mail. Thus, a well-prepared electronic manuscript can enhance the
+entire peer review process from author to reader while making the
+whole process less expensive. To this end, authors should follow the
+guidelines in this document when preparing their submissions to \textit{Physical Review Letters},
+ \textit{Reviews of Modern Physics}, \textit{Physical Review A-E, Physical Review X, Physical Review Applied. Physical Review Fluids, Physical Review Materials, Physical Review Accelerators and Beams,} and \textit{Physical Review Physics Education Research}.
+
+Updated versions of this document will be made available at \url{https://journals.aps.org/revtex/}. For more complete
+descriptions of how to use the \revtex\ 4.2 macros, please see the
+\textit{\revtex~4.2 Author's Guide} included with the \revtex~4.2
+distribution. Questions about \revtex\ 4.2 and using it to submit to APS journals may be
+emailed to \texttt{revtex@aps.org}.
+
+\section{Formatting}
+\subsection{Preprint, reprint, and twocolumn options}
+\revtex~4.2 offers a \classoption{reprint} class option to typeset a manuscript
+in a format that is a close approximation to the actual journal's appearance. It should
+be emphasized that this is only an \textit{approximation}; a manuscript may be substantially different
+in length or appearance after it goes through our production process. This is mostly due to the choice
+of fonts and the scaling of figures.
+
+\revtex\ 4.2 is designed to
+make it straightforward to switch between two-column and single-column
+formatting just by changing the class option. Authors may submit with
+either the \classoption{reprint} or the \classoption{twocolumn} class options.
+The \classoption{preprint} primarily does three things: It increases
+the font size to 12pt, increases the line spacing, and changes the
+formatting to single column.
+
+\subsection{Paper size}
+Manuscripts should be submitted to APS formatted for letter size
+paper. Papers are sent electronically to referees who may
+want to print them out. Letter size formatting ensures that this will
+be trouble free for all referees.
+
+\section{Marking up front matter}
+Perhaps the most important macros are those
+pertaining to the markup of the front matter (title, authors,
+affiliations, abstract, etc.). Note that proper
+use of the \revtex\ 4.2 macros means that explicit centering environments
+in the front matter are not needed and should not be used.
+
+\subsection{Title}
+The title of the manuscript should be specified using the \m{title} macro. A
+double backslash {\textbackslash\textbackslash} may be used to force a line break in a long
+title.
+
+\subsection{Authors, affiliations, and collaborations}
+\label{sec:authors}
+\revtex\ 4.2 makes it straightforward to input author names and link them up properly with affiliations. Authors should let \revtex\ 4.2 do the work of grouping authors and affiliations and, if using the superscript style, numbering affiliations. Please follow these guidelines:
+\begin{itemize}
+\item Use a single \m{author} macro for each author's name. \revtex\ 4.2 automatically puts in all commas and the word `and.'
+\item Use the \m{surname} macro to explicitly indicate if an author's family name consists of more than one name or if the family name is not the author's last name.
+\item The \m{email} macro may be used to specify an author's e-mail
+address. The \m{thanks} macro must not be used for this. Only the
+e-mail address itself may appear in the macro's required argument.
+\item The \m{homepage} macro may be used to specify a URL associated
+with an author. The \m{thanks} macro must not be used for this. Only the
+URL may appear in the macro's required argument.
+\item The \m{altaffiliation} macro may be used to specify an alternate
+affiliation or temporary address for an author. The \m{thanks} macro
+must not be used for this. Only the affiliation
+may appear in the macro's required argument.
+\item The \m{thanks} macro may be used only if one of the more
+specific macros list above does not apply.
+\item Use a single \m{affiliation} for each affiliation.
+\item Superscripts linking authors to affiliations must be
+accomplished using the \classoption{superscriptaddress} class option
+rather than putting in explicit superscripts by hand.
+\item A collaboration may be specified by using the \m{collaboration}
+macro. The \m{author} macro must not be used for collaborations.
+\end{itemize}
+\subsection{Abstract}
+The abstract must be specified using the \env{abstract}
+environment. Note that in \revtex\ 4.2, the abstract must come before
+the \m{maketitle} command. \revtex\ 4.2 now allows the the use of the \env{description}
+environment within the abstract to provide \textit{structured abstracts}. For instance, \textit{Physical Review C} would like authors to provide abstracts with sections summarizing the paper's \textbf{Background}, \textbf{Purpose}, \textbf{Method}, \textbf{Results}, and \textbf{Conclusions}. This can be accomplished in the following manner:
+\begin{verbatim}
+\begin{abstract}
+\begin{description}
+\item[Background] This part would describe the
+context needed to understand what the paper
+is about.
+\item[Purpose] This part would state the purpose
+of the present paper.
+\item[Method] This part describe the methods
+used in the paper.
+\item[Results] This part would summarize the
+results.
+\item[Conclusions] This part would state the
+conclusions of the paper.
+\end{description}
+\end{abstract}
+\end{verbatim}
+
+\section{References and footnotes}
+Authors are strongly encouraged
+to use Bib\TeX\ when preparing their bibliographies. If Bib\TeX\ is used, current production processes
+require that the \texttt{.bbl} file be included directly into the
+manuscript's main \texttt{.tex} file. \revtex\ 4.2 comes with two Bib\TeX\ style files for formatting
+references, one for the \textit{Physical Review} journals and one
+for \textit{Review of Modern Physics}. In 4.2, the Bib\TeX\ styles have been modified to display journal article titles in the bibliography.
+
+The following apply whether
+Bib\TeX\ is used or not.
+\begin{itemize}
+\item Authors should use the \m{cite} and \m{bibitem} commands to create
+bibliographies and to refer to items in the bibliography. ``By hand"
+numbering of references should be avoided.
+\item \revtex~4.2 provides new syntax for combining multiple citations into a single entry in the bibliography and for putting extra text before and after a reference. Please refer to \textit{\revtex~4.2 Author's Guide} included with the \revtex~4.2 distribution for full details.
+\item Footnotes must be specified using the \m{footnote}
+macro. \revtex\ 4.2 will place the footnotes in
+the bibliography for the \textit{Physical Review}
+journals. Please note that even if you don't use Bib\TeX, you may have to run Bib\TeX\ to get the footnotes to appear. Footnotes giving additional information about authors (such
+as e-mail addresses) must not be specified using the \m{footnote}
+macro (see Section~\ref{sec:authors}).
+\item Avoid custom footnotes using \m{footnotemark} and \m{footnotetext} [except in the context of tables (see
+Section~\ref{sec:tablenotes})].
+\item References should be formatted and specified according to the
+\textit{Physical Review Style Guide}. Note that using Bib\TeX\ automatically ensures this.
+\item URLs should be specified using the \m{url} macro. Bib\TeX\ will automatically take
+care of this if the \texttt{url} field is used.
+\item E-print identifiers should be included using the \m{eprint} macro. Bib\TeX\ will automatically take care of this if the \texttt{eprint} field is used.
+\end{itemize}
+
+Please see the \revtex~4.2 Author's Guide for new features in \revtex~4.2's APS Bib\TeX\ styles, including support for citing data sets, journals that use DOIs in place of page numbers, and journals that use year and issue instead of volume to uniquely identify articles.
+
+\section{Body of the paper}
+\subsection{Sectioning and cross-referencing}
+For sectioning a manuscript, the basic rule is to use the appropriate
+sectioning commands (\m{section}, \m{subsection}, \m{subsubsection},
+\textit{etc.}). Cross-referencing a section must be done by using the
+proper \m{label} and \m{ref} commands. Cross-referencing by hand is
+not allowed. \m{part}, \m{chapter}, and \m{subparagraph} should not be
+used.
+
+\subsection{Appendices}
+Appendices should be specified using the \m{appendix} command which
+specifies that all following sections create with the \m{section}
+commands are appendices. If there is only one appendix, then the
+\m{appendix*} command should be used instead.
+
+\subsection{Acknowledgments}
+Any acknowledgments should be included by using the
+\env{acknowledgments} environment. Note that in \revtex~4.2, this is
+an environment and not a command.
+
+\subsection{Counters}
+No counters may be created and the standard ones may not be
+altered. If an exceptional label is needed for an equation, the \m{tag}
+command (requires the \classoption{amsmath} class option) should be used. Please
+note that the use of the \m{tag} command may conflict with the use of the \classoption{hyperref} package
+due an incompatibility between \classoption{amsmath} and \classoption{hyperref}.
+
+\subsection{Fonts}
+It is preferable to avoid the older \TeX\ and \LaTeX\ 2.09 macros for
+controlling fonts such as \m{rm}, \m{it}, \textit{etc.} Rather, it is
+better to use the macros introduced in \LaTeXe. If the older font
+commands are used (they really should be avoided!), be sure to use
+curly braces to properly limit the extent of the font
+change. \verb+{\bf ...}+ is the correct method.
+Commands for controlling text and math font changes are summarized in
+Table~\ref{tab:fonts}.
+
+\begin{table}
+\caption{\label{tab:fonts}\LaTeXe\ and AMS-\LaTeX\ font summary.}
+\begin{ruledtabular}
+\begin{tabular}{lp{2in}}
+\m{textit} & Italics. Replaces \m{it}\\
+\m{textbf} & Bold face. Replaces \m{bf}\\
+\m{textrm} & Roman. Replaces \m{rm}\\
+\m{textsl} & Slanted. Replaces \m{sl}\\
+\m{textsc} & Small caps. Replaces \m{sc}\\
+\m{textsf} & Sans serif. Replaces \m{sf}\\
+\m{texttt} & Typewriter. Replaces \m{tt}\\
+\m{textmd} & Medium series\\
+\m{textnormal} & Normal\\
+\m{textup} & Upright\\
+\m{mathbf} & Bold face\\
+\m{mathcal} & Replaces \m{cal}\\
+\m{mathit} & Italics\\
+\m{mathnormal} & Replaces \m{mit}\\
+\m{mathsf} & Sans serif\\
+\m{mathtt} & Typewriter\\
+\m{mathfrak} & Fraktur: Requires \classoption{amsfonts} or \classoption{amssymb} class option\\
+\m{mathbb} & Bold blackboard: Requires \classoption{amsfonts} or \classoption{amssymb} class option\\
+\m{bm} & Bold Greek and other math symbols: Requires
+\verb+\usepackage{bm}+ and may require the \classoption{amsfonts} class
+option
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+
+Bold Greek letters and other bold math symbols should be accomplished
+with the use of \texttt{bm.sty} which is distributed as a required
+tool with the latest versions of \LaTeXe\ and should be loaded via
+\verb+\usepackage{bm}+. This package introduces the \m{bm}
+macro. Some bold characters may require using the
+\classoption{amsfonts} class option.
+
+New fonts may not be declared with \m{newfont}. Font attribute
+commands for selecting a font family, shape, and series are all
+disallowed; the standard \LaTeXe\ font selection macros list above
+should be used instead.
+
+Finally, the \m{symbol} macro is also not allowed.
+
+\subsection{Environments}
+\subsubsection{Lists}
+The standard list environments \texttt{itemize}, \texttt{enumerate},
+and \texttt{description} are allowed. The \m{item} macro with or without
+the optional argument is also allowed. Customization of the list environments
+(with macros such as \m{labelstyle}, \m{labelitemi}, \m{labelenumi},
+\m{itemsep}, etc.) is allowed but may be ignored in production.
+Generalized lists (\m{begin\{list\}}) and trivial lists
+(\m{begin\{trivlist\}}) are not allowed.
+
+\subsubsection{Other Environments}
+Creating generalized new environments with \m{newenvironment} is not
+allowed. Creating a new theorem environment with \m{newtheorem} is
+allowed though.
+
+The tabbing environment and the macros \m{=}, \m{$>$}, \m{`}, and
+\m{'} are allowed but may be ignored in production. Conversion
+programs used in production should recognize the escapes \m{a=},
+\m{a'}, and \m{a`} for using the corresponding accents within a
+tabbing environment though.
+
+The \env{verbatim} environment is allowed.
+
+\subsection{Boxes}
+Most boxes and macros to manipulate them are not allowed. These
+include \m{raisebox}, \m{parbox}, \m{minipage}, \m{rulebox},
+\m{framebox}, \m{mbox}, \m{fbox}, \m{savebox}, \m{newsavebox},
+\m{sbox}, \m{usebox}, and the environment \m{begin\{lrbox\}}. Rules
+produced with \m{rule} are not allowed.
+
+\subsubsection{Margin Notes}
+Margin notes created with \m{marginpar} are not allowed, as are the
+associated style parameters \m{marginparwidth}, \m{marginparsep}, and
+\m{marginparpush}.
+
+
+\section{Math Markup}
+In general, all math markup and the standard math environments from
+\LaTeXe\ are allowed. These include \m{begin\{math\}},
+\m{begin\{displaymath\}}, \m{begin\{equation\}},
+\m{begin\{eqnarray\}}, and \m{begin\{eqnarray*\}}. The shortcuts \$,
+\$\$, \m{[}, and \m{]} are allowed. In addition, authors may use
+almost all of the additional markup introduced by AMS-\LaTeX\ by using
+the \classoption{amsmath} class option. The explicit exceptions are
+\m{genfrac}, \m{boxed}, and \m{smash}. The markup contained in
+\texttt{amsextra} and \texttt{amsthm} may not be used
+though. Commutative diagrams created with the \texttt{amscd} package
+are acceptable.
+
+\section{Figures}
+\subsection{Figure inclusions}
+Figures should be included into a \revtex~4.2 manuscript by using the
+standard \LaTeXe\ macros. \LaTeXe\ includes
+several powerful packages for including the files in various
+formats. The two main packages are \texttt{graphics} and
+\texttt{graphicx}. Both offer a macro called
+\m{includegraphics};
+they mainly differ in how arguments for
+controlling figure placement (\textit{e.g.}, scaling and rotation)
+are passed to the \m{includegraphics}.
+
+The \env{figure} environment should be used to add a caption to the
+figure and to allow \LaTeX\ to number and place the figures where they
+fit best. If a figure needs to be referred to in the text,
+rather than manually numbering the figures a \m{label} should be added
+to the figure environment (best practice is to put the label within
+the argument of the \m{caption} command) and the \m{ref} macro should be used to
+reference this label. Figures that span the page should use the
+\m{figure*} environment. The \env{picture} environment must not be
+used directly (one can include an Encapsulated PostScript figure that
+was produced using the \env{picture} environment of course).
+
+\subsection{\label{sec:figplace}Figure placement}
+Figures should be placed as close as possible to the point where they are first
+referenced. There is no need to place all figures
+separately at the end of the manuscript and it is preferred that
+authors leave the figures in their natural locations. Authors may
+also find useful the \revtex~4.2 \classoption{floatfix} class option
+which adds emergency float placement processing to avoid ``stuck''
+floats which would otherwise be deferred to the end of the job (and
+can lead to the fatal \texttt{``Too many unprocessed floats''}
+message).
+
+
+\section{Tables}
+\label{sec:tables}
+The standard \LaTeXe\ table formatting environments are supported as is
+the use of the \texttt{longtable} package. Tables may be reformatted
+during production to meet APS style guidelines.
+Here are some helpful hints for trying to get tables formatted correctly:
+\begin{itemize}
+\item Use the \texttt{longtable} package to get tables to break
+across pages.
+\item The macro \m{squeezetable} will reduce the font size of the
+table. This macro must occur within a group outside the table
+environment. The proper markup is:
+\begin{verbatim}
+\begingroup
+\squeezetable
+\begin{table}
+...
+\end{table}
+\endgroup
+\end{verbatim}
+\item Try using the float placement option \texttt{H} which will
+enable \LaTeX\ to break a float across pages. Long tables are more
+attractively set with \env{longtable} however.
+\begin{verbatim}
+\begin{table}[H]
+\begin{ruledtabular}
+\begin{tabular}
+...
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+\end{verbatim}
+\end{itemize}
+
+\subsection{Doubled rules and table formatting}
+\revtex\ 4.2 provides the \env{ruledtabular} environment which
+automatically puts the scotch rules (double lines) around tables and
+formats all enclosed \env{tabular} environments to the full width of
+the tables and improves inter-column spacing. This environment should
+be used whenever possible.
+
+\subsection{Wide tables}
+When typesetting using \classoption{twocolumn}, tables can either span
+a single column or both columns. Using the '\verb+*+'-ed version of
+the \env{table} or \env{longtable} environments produces wide tables
+that span the columns.
+
+Tables that are very wide and that may be better typeset in a
+landscape orientation (rotated 90 degrees) should be enclosed in a
+\env{turnpage} environment. This will place the rotated table on its own
+page. Note that some dvi previewers may not be able to show the table
+properly, but \texttt{dvips} and \texttt{pdflatex} work correctly.
+
+\subsection{Table placement}
+Tables should be placed as close as possible to the point where they
+are first referenced. There is no need to place all tables separately
+at the end of the manuscript and this is not desirable for APS
+purposes. The class option \classoption{floatfix} may be helpful for
+table placement as well as figure placement (see Section~\ref{sec:figplace}).
+
+\subsection{Aligning columns on a decimal point}
+The standard \LaTeXe\ macro package \classoption{dcolumn} should be
+used to accomplish this.
+
+\subsection{Tablenotes}
+\label{sec:tablenotes}
+Footnotes in tables (tablenotes) should use the \m{footnote}
+macro. However, if more than one reference to the same footnote is
+needed, authors may use \m{footnotetext} and \m{footnotemark}. This
+will produce notes (labeled by lower-case roman letters) inserted
+below the table rather than in the reference section or at the bottom
+of the page.
+
+
+\section{Author-defined macros}
+Authors may define convenience macros to save keystrokes. This means
+that the macros may not invoke \TeX\ macros such as \m{if} or other
+context dependent commands. Also, \LaTeXe\ provides three macros for
+declaring new commands: \m{providecommand}, \m{newcommand}, and
+\m{renewcommand} (as well as their `\verb+*+'-ed versions). These
+should be used. Authors may not use \TeX\relax's low-level commands
+\m{def}, \m{edef}, and \m{gdef}.
+
+\section{Summary}
+To ensure the best use of \TeX\ manuscripts, authors need to follow
+the guidelines specified here. Use of low-level formatting commands to
+finely control horizontal and vertical spacing may be ignored during
+production, or even worse, make it impossible to convert the
+manuscript to XML. Authors should keep
+things as simple as possible and correctly use the proper \revtex~4.2
+or \LaTeXe\ macros. Any questions about usage may be directed to
+\texttt{revtex@aps.org}.

+\section{Introduction}
+
+This is the author's guide to \revtex~4.2, the preferred submission
+format for all APS and AIP journals. This guide is intended to be a concise
+introduction to \revtex~4.2. The documentation has been separated out
+into smaller units to make it easier to locate essential
+information.
+
+The following documentation is also part of the \revtex~4.2
+distribution. Updated versions of these will be maintained at
+the \revtex~4.2 homepage located at \url{http://journals.aps.org/revtex/}.
+\begin{itemize}
+\item \textit{APS Author Guide for \revtex~4.2}
+\item \textit{Author's Guide to AIP Substyles for \revtex~4.2}
+\item \textit{\revtex~4.2 Command and Options Summary}
+\end{itemize}
+This guide assumes a working \revtex~4.2
+installation. Please see the installation instructions included with the
+distribution.
+\subsection{Changes in \revtex~4.2}
+The \revtex\ system for \LaTeX\ began its development in 1986 and has gone through three major revisions since then. \revtex~4 was released in August, 2001. Since that time, many user requests for new features were received. These requests were taken care of in the \revtex~4.1, which was released in August, 2010. \revtex~4.2 is the current release.
+
+\revtex~4.2 incorporates the following changes:
+
+\begin{itemize}
+\item \textbf{Added support for additional APS journals, \textit{Physical Review X}, \textit{Physical Review Accelerators and Beams}, \textit{Physical Review Applied}, \textit{Physical Review Fluids}, \textit{Physical Review Materials}, and \textit{Physical Review Physics Education Research}.} There are new options \texttt{prx}, \texttt{prab}, \texttt{prapplied}, \texttt{prfluids}, and \texttt{prmaterials}, and \texttt{prper}.
+
+\item \textbf{Added a unified \texttt{physrev} option for \textit{Physical Review} journal style (the \textit{Phys. Rev.} journals have no or few variations).}
+
+\item \textbf{The \texttt{prb} option now conforms with \textit{Physical Review B}'s updated style that uses the same non-superscripted citations as other APS journals}.
+
+\item \textbf{Added support for additional AIP journals, \textit{AIP Advances}, \textit{Applied Physics Letters Materials}, and \textit{Structural Dynamics} as well as \textit{AIP Conference Proceedings}. There are new options \texttt{adv}, \texttt{apm}, \texttt{sd}, and \texttt{cp}.}
+
+\item \textbf{Added support for the Society of Rheology (\texttt{sor}) and its journal, \textit{Journal of Rheology} (\texttt{jor}).}
+
+\item \textbf{The \texttt{reprint} style for AIP's journal JMP was changed to one-column formatting.}
+
+\item \textbf{For all APS journal options, complete article titles are now displayed in bibliography entries citing journal articles when using Bib\TeX\ by default.}
+
+\item \textbf{In the \textit{Phys. Rev.} Bib\TeX\ style file, article titles in the bibliography are set in roman font}.
+
+\item \textbf{The behavior of the \texttt{noeprints} option has been improved}.
+
+\item \textbf{Support has been added for citing data sets in the Bib\TeX\ styles}.
+
+\item \textbf{Support for citing journals that use a DOI instead of pages or article identifiers has been improved (for APS \textit{Phys. Rev.} Bib\TeX\ style)}.
+
+\item \textbf{The indentation of tables of contents have been improved}.
+
+\item \textbf{The \texttt{onecolumn} option no longer defaults to creating a separate title page}.
+
+\item \textbf{The \texttt{showpacs} option is completely ignored now}.
+
+\item \textbf{A bug when using \texttt{booktabs.sty} has been fixed}.
+
+\item \textbf{The formatting of references for some commonly cited journals has been improved in the \textit{Phys. Rev.} Bib\TeX\ style}.
+
+\item \textbf{URLs generated for DOIs now use \texttt{https://doi.org/} as the base in the Bib\TeX\ styles.}
+
+\item \textbf{URLs generated for arXiv.org e-print identifiers now use \texttt{https://arXiv.org/abs/} as the base in the Bib\TeX\ styles.}
+
+\end{itemize}
+
+\subsection{\revtex~4 Backwards Compatibility}
+Documents prepared under \revtex~4 and \revtex~4.1 should process correctly under \revtex~4.2. However, the formatting of the pages and, if using Bib\TeX, the references may change. Under 4.2, articles typeset with the \texttt{prb} option will be typeset \texttt{cite} commands differently and adjacent punctuation may need to be moved accordingly. Default behaviors some other options may also have changed as described above.
+
+
+
+\subsection{Submitting to APS Journals}
+
+Authors using \revtex~4.2 to prepare a manuscript for submission to
+\textit{Physical Review Letters}, \textit{Physical Review}, \textit{Reviews of Modern Physics},
+or other APS journals must also read the companion document \textit{APS Author Guide for \revtex~4.2}
+distributed with \revtex\ and follow the guidelines detailed there.
+
+The \revtex~4.2 distribution includes both a template
+(\file{apstemplate.tex}) and a sample document (\file{apssamp.tex}).
+The template is a good starting point for a manuscript. In the
+following sections are instructions that should be sufficient for
+creating a paper using \revtex~4.2.
+
+Further information about submissions to the American
+Physical Society may be found at \url{http://journals.aps.org/revtex/}.
+
+\subsection{Submitting to AIP Journals}
+
+\revtex~4.2 includes support for the journals of the American Institute of Physics.
+The style files and authoring guides for these journals are distributed as part
+\revtex~4.2 distribution. The distribution includes both a template
+(\file{aiptemplate.tex}) and a sample document (\file{aipsamp.tex}).
+The template is a good starting point for a manuscript. In the
+following sections are instructions that should be sufficient for
+creating a paper using \revtex~4.2.
+
+
+
+More information may be found at
+\url{http://publishing.aip.org/authors/preparing-your-manuscript}. Please consult the \textit{Author's Guide to AIP Substyles for \revtex~4.2} for more information about submissions to AIP journals, AIP styles files, and other AIP-specific information.
+
+\subsection{Contact Information}\label{sec:aipresources}%
+Any bugs, problems, or inconsistencies with \revtex\ or the APS journal style files should be reported to
+\revtex\ support at \verb+revtex@aps.org+. Reports should include information on the error and a \textit{small}
+sample document that manifests the problem if possible (please don't send large files!). Issues related to the AIP journal styles should be sent directly to \verb+tex@aip.org+.
+
+\section{Some \LaTeXe\ Basics}
+\revtex~4.2 must sometimes patch the underlying
+\LaTeX\ kernel. This means that \revtex~4.2 requires a fairly recent version of
+\LaTeXe. Versions prior to 2005/12/01 may not work
+correctly. \revtex~4.2 will be maintained to be compatible with future
+versions of \LaTeXe.
+
+\subsection{Useful \LaTeXe\ Markup}
+\LaTeXe\ markup is the preferred way to accomplish many basic tasks.
+
+\subsubsection{Fonts}
+
+Because \revtex~4.2 is based upon \LaTeXe, it inherits all of the
+macros used for controlling fonts. Of particular importance are the
+\LaTeXe\ macros \cmd{\textit}, \cmd{\textbf}, \cmd{\texttt} for changing to
+an italic, bold, or typewriter font respectively. One should always
+use these macros rather than the lower-level \TeX\ macros \cmd{\it},
+\cmd{\bf}, and \cmd{\tt}. The \LaTeXe\ macros offer
+improvements such as better italic correction and scaling in super-
+and subscripts for example. Table~\ref{tab:fonts}
+summarizes the font selection commands in \LaTeXe.
+
+\begin{table}
+\caption{\label{tab:fonts}\LaTeXe\ font commands}
+\begin{ruledtabular}
+\begin{tabular}{ll}
+\multicolumn{2}{c}{\textbf{Text Fonts}}\\

+\subsubsection{User-defined macros}
+\LaTeXe\ provides several macros that enable users to easily create new
+macros for use in their manuscripts:
+\begin{itemize}
+\footnotesize
+\item \cmd\newcommand\marg{\\command}\oarg{narg}\oarg{opt}\marg{def}
+\item \cmd\newcommand\verb+*+\marg{\\command}\oarg{narg}\oarg{opt}\marg{def}
+\item \cmd\renewcommand\marg{\\command}\oarg{narg}\oarg{opt}\marg{def}
+\item \cmd\renewcommand\verb+*+\marg{\\command}\oarg{narg}\oarg{opt}\marg{def}
+\item \cmd\providecommand\marg{\\command}\oarg{narg}\oarg{opt}\marg{def}
+\item \cmd\providecommand\verb+*+\marg{\\command}\oarg{narg}\oarg{opt}\marg{def}
+\end{itemize}
+Here \meta{\\command} is the name of the macro being defined,
+\meta{narg} is the number of arguments the macro takes,
+\meta{opt} are optional default values for the arguments, and
+\meta{def} is the actually macro definiton. \cmd\newcommand\ creates a
+new macro, \cmd\renewcommand\ redefines a previously defined macro,
+and \cmd\providecommand\ will define a macro only if it hasn't
+been defined previously. The *-ed versions are an optimization that
+indicates that the macro arguments will always be ``short'' arguments. This is
+almost always the case, so the *-ed versions should be used whenever
+possible.
+
+The use of these macros is preferred over using plain \TeX's low-level
+macros such as
+\cmd\def{},\cmd\edef{}, and \cmd\gdef{}. APS authors must follow the
+\textit{APS Author Guide for \revtex~4.2} when defining macros.
+
+\subsubsection{Symbols}
+
+\LaTeXe\ has added some convenient commands for some special symbols
+and effects. These are summarized in Table~\ref{tab:special}. See
+\cite{Guide} for details.
+
+\begin{table}
+\caption{\label{tab:special}\LaTeXe\ commands for special symbols and effects}
+\begin{ruledtabular}
+\begin{tabular}{lc}
+Command & Symbol/Effect\\
+\cmd\textemdash & \textemdash\\
+\cmd\textendash & \textendash\\
+\cmd\textexclamdown & \textexclamdown\\
+\cmd\textquestiondown & \textquestiondown\\
+\cmd\textquotedblleft & \textquotedblleft\\
+\cmd\textquotedblright & \textquotedblright\\
+\cmd\textquoteleft & \textquoteleft\\
+\cmd\textquoteright & \textquoteright\\
+\cmd\textbullet & \textbullet\\
+\cmd\textperiodcentered & \textperiodcentered\\
+\cmd\textvisiblespace & \textvisiblespace\\
+\cmd\textcompworkmark & Break a ligature\\
+\cmd\textcircled\marg{char} & Circle a character\\
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+
+\LaTeXe\ provides additional symbols in a
+separate package called \classname{latexsym}. To use these symbols, include
+the package using:
+\begin{verbatim}
+\usepackage{latexsym}
+\end{verbatim}
+
+\subsection{Using \LaTeXe\ packages with \revtex}\label{sec:usepackage}%
+
+Many \LaTeXe\ packages are available, for instance, on CTAN at
+\url{http://www.ctan.org/tex-archive/macros/latex/required/}
+and at
+\url{http://www.ctan.org/tex-archive/macros/latex/contrib/}. Full \TeX\ distributions
+such as \TeX\
+Live \url{http://www.tug.org/texlive/} provide an excellent and complete installation of \TeX\ that is
+easy to maintain. Some of these packages
+are automatically loaded by \revtex~4.2 when certain class options are
+invoked and are, thus, ``required.'' They will either be distributed
+with \revtex\ or are already included with a standard \LaTeXe\
+distribution.
+
+Required packages are automatically loaded by \revtex\ on an as-needed
+basis. Other packages should be loaded using the
+\cmd\usepackage\ command. To load the
+\classname{hyperref} package, the document preamble might look like:
+\begin{verbatim}
+\documentclass{revtex4-2}
+\usepackage{hyperref}
+\end{verbatim}
+
+Some common (and very useful) \LaTeXe\ packages are \textit{a priori}
+important enough that \revtex~4.2 has been designed to be specifically
+compatible with them.
+A bug stemming from the use of one of these packages in
+conjunction with any of the APS journals may be reported by contacting
+\revtex\ support.
+\begin{description}
+\item[\textbf{AMS packages}] \revtex~4.2 is compatible with and depends
+ upon the AMS packages
+\classname{amsfonts},
+\classname{amssymb}, and
+\classname{amsmath}. In fact, \revtex~4.2 requires use of these packages
+to accomplish some common tasks. See Section~\ref{sec:math} for more.
+\revtex~4.2 requires version 2.0 or higher of the AMS-\LaTeX\ package.
+
+\item[\textbf{array and dcolumn}]
+The \classname{array} and \classname{dcolumn} packages are part of
+\LaTeX's required suite of packages. \classname{dcolumn} is required
+to align table columns on decimal points (and it in turn depends upon
+the \classname{array} package).
+
+\item[\textbf{longtable}]
+\file{longtable.sty} may be used for large tables that will span more than one
+page. \revtex~4.2 dynamically applies patches to longtable.sty so that
+it will work in two-column mode.
+
+\item[\textbf{hyperref}] \file{hyperref.sty} is a package that is
+used for putting hypertext links into \LaTeXe\ documents.
+\revtex~4.2 has hooks to allow e-mail addresses and URL's to become
+hyperlinks if \classname{hyperref} is loaded.
+
+\item[\textbf{booktabs}] \revtex~4.2 improves compatibility with \classname{booktabs.sty}.
+
+\end{description}
+
+Other packages will conflict with \revtex~4.2 and should be
+avoided. Usually such a conflict arises because the package adds
+enhancements that \revtex~4.2 already includes. Here are some common
+packages that clash with \revtex~4.2:
+\begin{description}
+\item[\textbf{multicol}] \file{multicol.sty} is a package by Frank Mittelbach
+that adds support for multiple columns. In fact, early versions of
+\revtex~4.2 used \file{multicol.sty} for precisely this. \revtex\
+incorporates its own support for multiple-column typesetting.
+
+\item[\textbf{cite}] Donald Arseneau's \file{cite.sty} is often used to provide
+support for sorting a \cmd\cite\ command's arguments into numerical
+order and to collapse consecutive runs of reference numbers. \revtex~4.2
+has this functionality built-in already via the \classname{natbib} package.
+
+\item[\textbf{mcite}] \revtex~4.2 already contains a lot of this
+functionality through its updated syntax for the \cmd\cite\ command and
+the latest \classname{natbib} package.
+
+\item[\textbf{endfloat}] The same functionality can be accomplished
+using the \classoption{endfloats} class option.
+
+\item[\textbf{float}] \texttt{float.sty} provides a mechanism for creating new float classes with just a few commands. \revtex~4.2 has limited compatible with float.sty. If attempting to use this package, be sure to put any \cmd\newfloat\ commands after the \verb+\begin{document}+ line.
+
+\end{description}
+
+\section{The Document Preamble}
+
+The preamble of a \LaTeX\ document is the set of commands that precede
+the \envb{document} line. It contains a
+\cmd\documentclass\ line to load the \revtex~4.2 class (\textit{i.e.},
+all of the \revtex~4.2 macro definitions), \cmd\usepackage\ macros to
+load other macro packages, and other macro definitions.
+
+\subsection{The \emph{documentclass} line}
+The basic formatting of the manuscript is controlled by setting
+\emph{class options} using
+\cmd\documentclass\oarg{options}\aarg{\classname{revtex4-2}}.
+The optional arguments that appear in the square brackets control the layout of the
+document. At this point, one only needs to choose:
+\begin{itemize}
+\item Either the \classoption{aps} (default) or \classoption{aip} society option
+\item One of the chosen society's journal styles such as \classoption{prl} or \classoption{apl}
+\item A layout option such as \classoption{preprint} (single-column formatting), \classoption{reprint} (an approximation
+to the selected journal's actual layout which may be one- or two-column depending on the journal), or \classoption{twocolumn}
+\end{itemize}
+Usually, one would want to use \classoption{preprint} for draft papers. Paper size options are also
+available as well. In particular, \classoption{a4paper} is available
+as well as the rest of the standard \LaTeX\ paper sizes. A
+full list of class options is given in the \textit{\revtex~4.2 Command
+and Options Summary}.
+
+\subsection{Loading other packages}
+Other packages may be loaded into a \revtex~4.2 document by using the
+standard \LaTeXe\ \cmd\usepackage\ command. For instance, to load
+the \classoption{graphics} package, one would use
+\verb+\usepackage{graphics}+.
+
+\section{The Front Matter}\label{sec:front}
+
+After choosing the basic look and feel of the document by selecting
+the appropriate class options and loading in whatever other macros are
+needed, one is ready to move on to creating a new manuscript. After
+the preamble, be sure to put in a \envb{document} line (and put
+in an \enve{document} as well). This section describes the macros
+\revtex~4.2 provides for formatting the front matter of the
+article. The behavior and usage of these macros can be quite
+different from those provided in the \LaTeXe\ \classname{article} class.
+\subsection{Setting the title}
+
+The title of the manuscript is simply specified by using the
+\cmd\title\aarg{title} macro. A \verb+\\+ may be used to put a line
+break in a long title.
+
+\subsection{Specifying a date}%
+
+The \cmd\date\marg{date} command outputs the date on the
+manuscript. Using \cmd\today\ will cause \LaTeX{} to insert the
+current date whenever the file is run:
+\begin{verbatim}
+\date{\today}
+\end{verbatim}
+
+\subsection{Specifying authors and affiliations}
+
+The \revtex~4.2 macros for specifying authors and their affiliations are designed
+ to save labor for authors and during production. Authors and affiliations are
+arranged into groupings called, appropriately enough, \emph{author
+groups}. Each author group is a set of authors who share the same set
+of affiliations. Author names are specified with the \cmd\author\
+macro while affiliations (or addresses) are specified with the
+\cmd\affiliation\ macro. Author groups are specified by sequences of
+\cmd\author\ macros followed by \cmd\affiliation\ macros. An
+\cmd\affiliation\ macro applies to all previously specified
+\cmd\author\ macros which don't already have an affiliation supplied.
+
+For example, if Bugs Bunny and Roger Rabbit are both at Looney Tune
+Studios, while Mickey Mouse is at Disney World, the markup would be:
+\begin{verbatim}
+\author{Bugs Bunny}
+\author{Roger Rabbit}
+\affiliation{Looney Tune Studios}
+\author{Mickey Mouse}
+\affiliation{Disney World}
+\end{verbatim}
+The default is to display this as
+\begin{center}
+Bugs Bunny and Roger Rabbit\\
+\emph{Looney Tune Studios}\\
+Mickey Mouse\\
+\emph{Disney World}\\
+\end{center}
+This layout style for displaying authors and their affiliations is
+chosen by selecting the class option
+\classoption{groupedaddress}. Journal styles usually default this option,
+ so it need not be specified explicitly. The other major way of displaying this
+information is to use superscripts on the authors and
+affiliations. This can be accomplished by selecting the class option
+\classoption{superscriptaddress}. To achieve the display
+\begin{center}
+Bugs Bunny,$^{1}$ Roger Rabbit,$^{1,2}$ and Mickey Mouse$^{2}$\\
+\emph{$^{1}$Looney Tune Studios}\\
+\emph{$^{2}$Disney World}\\
+\end{center}
+one would use the markup
+\begin{verbatim}
+\author{Bugs Bunny}
+\affiliation{Looney Tune Studios}
+\author{Roger Rabbit}
+\affiliation{Looney Tune Studios}
+\affiliation{Disney World}
+\author{Mickey Mouse}
+\affiliation{Disney World}
+\end{verbatim}
+
+Note that \revtex~4.2 takes care of any commas and \emph{and}'s that join
+the author names together and font selection, as well as any
+superscript numbering. Only the author names and affiliations should
+be given within their respective macros. See below for further information
+regarding the proper way to add footnotes to author names and affiliations.
+
+There is a third class option, \classoption{unsortedaddress}, for
+controlling author/affiliation display. The default
+\classoption{groupedaddress} will actually sort authors into the
+approriate author groups if one chooses to specify an affiliation for
+each author. The markup:
+\begin{verbatim}
+\author{Bugs Bunny}
+\affiliation{Looney Tune Studios}
+\author{Mickey Mouse}
+\affiliation{Disney World}
+\author{Roger Rabbit}
+\affiliation{Looney Tune Studios}
+\end{verbatim}
+will result in the same display as for the first case given
+above even though Roger Rabbit is specified after Mickey Mouse. To
+avoid Roger Rabbit being moved into the same author group as Bugs
+Bunny, use the
+\classoption{unsortedaddress} option instead. In general, it is safest
+to list authors in the order they should appear and specify
+affiliations for multiple authors rather than one at a time. This will
+afford the most independence for choosing the display option. Finally,
+it should be mentioned that the affiliations for the
+\classoption{superscriptaddress} are presented and numbered
+in the order that they are encountered. These means that the order
+will usually follow the order of the authors. An alternative ordering
+can be forced by including a list of \cmd\affiliation\ commands before
+the first \cmd{\author} in the desired order. Then use the exact same
+text for each affilation when specifying them for each author.
+
+If an author doesn't have an affiliation, the \cmd\noaffiliation\
+macro may be used in the place of an \cmd\affiliation\ macro.
+
+
+\subsubsection{Collaborations}
+
+A collaboration name can be specified with the \cmd\collaboration\
+command. This is very similar to the \cmd\author\ command. In \revtex~4.2, it can
+be used with both the \classoption{superscriptaddress} and \classoption{groupedaddress} class options. The
+\cmd\collaboration\ command should appear at the end of the list of
+authors. The collaboration name will be appear centered in parentheses
+between the list of authors and the list of
+affiliations. Because collaborations
+don't normally have affiliations, one needs to follow the
+\cmd\collaboration\ with \cmd\noaffiliation.
+
+\subsubsection{Footnotes for authors, collaborations, affiliations or title}\label{sec:footau}
+
+Often one wants to specify additional information associated with an
+author, collaboration, or affiliation such as an e-mail address, an
+alternate affiliation, or some other ancillary information.
+\revtex~4.2 introduces several new macros just for this purpose. They
+are:
+\begin{itemize}
+\item\cmd\email\oarg{optional text}\aarg{e-mail address}
+\item\cmd\homepage\oarg{optional text}\aarg{URL}
+\item\cmd\altaffiliation\oarg{optional text}\aarg{affiliation}
+\item\cmd\thanks\aarg{miscellaneous text}
+\end{itemize}
+In the first three, the \emph{optional text} will be prepended before the
+actual information specified in the required argument. In the APS journal style files, \cmd\email\ and \cmd\homepage\ no longer have a default value. However, in the AIP styles, each have a default text for their optional arguments
+(`Electronic address:' and `URL:' respectively). The \cmd\thanks\
+macro should only be used if one of the other three do not apply. Any
+author name can have multiple occurences of these four macros. Note
+that unlike the
+\cmd\affiliation\ macro, these macros only apply to the \cmd\author\
+that directly precedes it. Any \cmd\affiliation\ \emph{must} follow
+the other author-specific macros. A typical usage might be as follows:
+\begin{verbatim}
+\author{Bugs Bunny}
+\email[E-mail me at: ]{bugs@looney.com}
+\homepage[Visit: ]{http://looney.com/}
+\altaffiliation[Permanent address: ]
+ {Warner Brothers}
+\affiliation{Looney Tunes}
+\end{verbatim}
+This would result in the footnote ``E-mail me at: \texttt{bugs@looney.com},
+Visit: \texttt{http://looney.com/}, Permanent address: Warner
+Brothers'' being attached to Bugs Bunny. Note that:
+\begin{itemize}
+\item Only an e-mail address, URL, or affiliation should go in the
+required argument in the curly braces.
+\item The font is automatically taken care of.
+\item An explicit space is needed at the end of the optional text if one is
+desired in the output.
+\item Use the optional arguments to provide customized
+text only if there is a good reason to.
+\end{itemize}
+
+The \cmd\collaboration\ , \cmd\affiliation\ , or even \cmd\title\ can
+also have footnotes attached via these commands. If any ancillary data
+(\cmd\thanks, \cmd\email, \cmd\homepage, or
+\cmd\altaffiliation) are given in the wrong context (e.g., before any
+\cmd\title, \cmd\author, \cmd\collaboration, or \cmd\affiliation\
+command has been given), then a warning is given in the \TeX\ log, and
+the command is ignored.
+
+Duplicate sets of ancillary data are merged, giving rise to a single
+shared footnote. However, this only applies if the ancillary data are
+identical: even the order of the commands specifying the data must be
+identical. Thus, for example, two authors can share a single footnote
+indicating a group e-mail address.
+
+Duplicate \cmd\affiliation\ commands may be given in the course of the
+front matter, without the danger of producing extraneous affiliations
+on the title page. However, ancillary data should be specified for
+only the first instance of any particular institution's
+\cmd\affiliation\ command; a later instance with different ancillary
+data will result in a warning in the \TeX\ log.
+
+It is preferable to arrange authors into
+sets. Within each set all the authors share the same group of
+affiliations. For each author, give the \cmd\author\ (and appropriate
+ancillary data), then follow this author group with the needed group
+of \cmd\affiliation\ commands.
+
+If affiliations have been listed before the first
+\cmd\author\ macro to ensure a particular ordering, be sure
+that any later \cmd\affiliation\ command for the given institution is
+an exact copy of the first, and also ensure that no ancillary data is
+given in these later instances.
+
+
+Each journal class option has a default behavior for the placement of these
+ancillary information footnotes. For instance, the \classoption{prb} option puts all
+such footnotes at the start of the bibliography while the \classoption{prl}
+journal styles displays them on the first page. One can override a
+journal style's default behavior by specifying explicitly the class
+option
+\classoption{bibnotes} (puts the footnotes at the start of the
+bibliography) or \classoption{nobibnotes} (puts them on the first page).
+Please consult the documentation for the various journal style files for further information.
+
+\subsubsection{Specifying first names and surnames}
+
+Many authors have names in which either the surname appears first
+or in which the surname is made up of more than one name. To ensure
+that such names are accurately captured for indexing and other
+purposes, the \cmd\surname\ macro should be used to indicate which portion
+of a name is the surname. Similarly, there is a \cmd\firstname\ macro
+as well, although usage of \cmd\surname\ should be sufficient. If an
+author's surname is a single name and written last, it is not
+necessary to use these macros. These macros do nothing but indicate
+how a name should be indexed. Here are some examples:
+\begin{verbatim}
+\author{Andrew \surname{Lloyd Weber}}
+\author{\surname{Mao} Tse-Tung}
+\end{verbatim}
+
+\subsection{The abstract}
+An abstract for a paper is specified by using the \env{abstract}
+environment:
+\begin{verbatim}
+\begin{abstract}
+Text of abstract
+\end{abstract}
+\end{verbatim}
+Note that in \revtex~4.2 the abstract must be specified before the
+\cmd\maketitle\ command and there is no need to embed it in an explicit
+minipage environment.
+
+\subsubsection{Structured abstracts}
+A new feature in \revtex~4.2 is support for \textit{structured abstracts}. A ``structured" abstract is an abstract divided into labeled sections. For instance, \textit{Physical Review C} would like authors to provide abstracts with sections summarizing the paper's \textbf{Background}, \textbf{Purpose}, \textbf{Method}, \textbf{Results}, and \textbf{Conclusions}. This can be accomplished by using the \texttt{description} environment within the \texttt{abstract} environment. For example:
+\begin{verbatim}
+\begin{abstract}
+\begin{description}
+\item[Background] This part would describe the
+context needed to understand what the paper
+is about.
+\item[Purpose] This part would state the purpose
+of the present paper.
+\item[Method] This part describe the methods
+used in the paper.
+\item[Results] This part would summarize the
+results.
+\item[Conclusions] This part would state the
+conclusions of the paper.
+\end{description}
+\end{abstract}
+\end{verbatim}
+
+\subsection{PACS codes}
+PACS codes are obsolete. The \classoption{showpacs} option does nothing, but is present so that older documents may still be processed under \revtex~4.2.
+
+\subsection{Keywords}
+A \cmd\keywords\ macro may also be used to indicate keywords for the
+article.
+\begin{verbatim}
+\keywords{nuclear form; yrast level}
+\end{verbatim}
+This will be displayed below the abstract and PACS (if supplied). Like
+PACS codes, the actual display of the the keywords is controlled by
+two classoptions: \classoption{showkeys} and
+\classoption{noshowkeys}. An explicit \classoption{showkeys} must be
+included in the \cmd\documentclass\ line to display the keywords.
+
+\subsection{Institutional report numbers}
+Institutional report numbers can be specified using the \cmd\preprint\
+macro. If the \classoption{preprintnumbers} class option is specified, these will be displayed in the upper right corner of the first page. Multiple \cmd\preprint\ macros maybe supplied (space is
+limited though, so only three or less may actually fit). Please note that the \classoption{preprint} class option does not automatically invoke \classoption{preprintnumbers}.
+
+\subsection{maketitle}
+After specifying the title, authors, affiliations, abstract, PACS
+codes, and report numbers, the final step for formatting the front
+matter of the manuscript is to execute the \cmd\maketitle\ macro by
+simply including it:
+\begin{verbatim}
+\maketitle
+\end{verbatim}
+The \cmd\maketitle\ macro must follow all of the macros listed
+above. The macro will format the front matter in accordance with the various
+class options that were specified in the
+\cmd\documentclass\ line (either implicitly through defaults or
+explicitly).
+
+\section{The body of the paper}
+
+For typesetting the body of a paper, \revtex~4.2 relies heavily on
+standard \LaTeXe\ and other packages (particulary those that are part
+of AMS-\LaTeX). Users unfamiliar with these packages should read the
+following sections carefully.
+
+\subsection{Section headings}
+
+Section headings are input as in \LaTeX.
+The output is similar, with a few extra features.
+
+Four levels of headings are available in \revtex{}:
+\begin{quote}
+\cmd\section\marg{title text}\\
+\cmd\subsection\marg{title text}\\
+\cmd\subsubsection\marg{title text}\\
+\cmd\paragraph\marg{title text}
+\end{quote}
+
+Use the starred form of the command to suppress the automatic numbering; e.g.,
+\begin{verbatim}
+\section*{Introduction}
+\end{verbatim}
+
+To label a section heading for cross referencing, best practice is to
+place the \cmd\label\marg{key} within the argument specifying the heading:
+\begin{verbatim}
+\section{\label{sec:intro}Introduction}
+\end{verbatim}
+
+In some journal substyles, such as those of the APS,
+all text in the \cmd\section\ command is automatically set uppercase.
+If a lowercase letter is needed, use \cmd\lowercase\aarg{x}.
+For example, to use ``He'' for helium in a \cmd\section\marg{title text} command, type
+\verb+H+\cmd\lowercase\aarg{e} in \marg{title text}.
+
+Use \cmd\protect\verb+\\+ to force a line break in a section heading.
+(Fragile commands must be protected in section headings, captions, and
+footnotes and \verb+\\+ is a fragile command.)
+
+\subsection{Paragraphs and General Text}
+
+Paragraphs always end with a blank input line. Because \TeX\
+automatically calculates linebreaks and word hyphenation in a
+paragraph, it is not necessary to force linebreaks or hyphenation. Of
+course, compound words should still be explicitly hyphenated, e.g.,
+``author-prepared copy.''
+
+Use directional quotes for quotation marks around quoted text
+(\texttt{``xxx''}), not straight double quotes (\texttt{"xxx"}).
+For opening quotes, use one or two backquotes; for closing quotes,
+use one or two forward quotes (apostrophes).
+
+\subsection{One-column vs. two-column layouts}\label{sec:widetext}
+
+One of the hallmarks of \textit{Physical Review} and many of the AIP journals is their two-column
+formatting. \revtex~4.2 provides the \classoption{reprint} class option that provides for each
+journal class option a close approximation to the journal's actual production formatting. Note that
+the \classoption{reprint} option will give either one or two-column formatting as appropriate for the particular journal.
+For most APS and AIP journals, the \classoption{reprint} option will take care of formatting the front matter
+(including the abstract) as a single column and will typeset the body in two columns. \revtex~4.2 has its own
+built-in two-column formatting macros to provide well-balanced columns as well as reasonable control over the placement of floats in either
+one- or two-column modes. When drafting papers, it is common to use a one-column format. This is best achieved by using the
+\classoption{preprint} class option. Authors may override a particular journal's formatting by using the lower level options \classoption{onecolumn} and \classoption{twocolumn}, but best practice is to stick with the \classoption{preprint} and \classoption{reprint} options.
+
+Please note that the \classoption{reprint} class option is only an \textit{approximation} of a journal's final layout. Because of font differences, figure rescaling, and other factors, authors should not expect the \classoption{reprint} option to give fully accurate estimates of an article's ultimate length after being typeset for the journal.
+
+Occasionally it is necessary to change the formatting from two-column to
+one-column to better accommodate very long equations that are more
+easily read when typeset to the full width of the page. This is
+accomplished using the \env{widetext} environment:
+\begin{verbatim}
+\begin{widetext}
+long equation goes here
+\end{widetext}
+\end{verbatim}
+In two-column mode, this will temporarily return to one-column mode,
+balancing the text before the environment into two short columns, and
+returning to two-column mode after the environment has
+finished. \revtex~4.2 will also add horizontal rules to guide the
+reader's eye through what may otherwise be a confusing break in the
+flow of text. The
+\env{widetext} environment has no effect on the output under the
+\classoption{preprint} class option because this already uses
+one-column formatting.
+
+Use of the \env{widetext} environment should be restricted to the bare
+minimum of text that needs to be typeset this way. However, short pieces
+of paragraph text and/or math between nearly contiguous wide equations
+should be incorporated into the surrounding wide sections.
+
+Low-level control over the column grid can be accomplished with the
+\cmd\onecolumngrid\ and \cmd\twocolumngrid\ commands. Using these, one
+can avoid the horizontal rules added by \env{widetext}. These commands
+should only be used if absolutely necessary. Wide figures and tables
+should be accommodated using the proper \verb+*+ environments.
+
+\subsection{Cross-referencing}\label{sec:xrefs}
+
+\revtex{} inherits the \LaTeXe\ features for labeling and cross-referencing
+section headings, equations, tables, and figures. This section
+contains a simplified explanation of these cross-referencing features.
+The proper usage in the context of section headings, equations,
+tables, and figures is discussed in the appropriate sections.
+
+Cross-referencing depends upon the use of ``tags,'' which are defined by
+the user. The \cmd\label\marg{key} command is used to identify tags for
+\revtex. Tags are strings of characters that serve to label section
+headings, equations, tables, and figures that replace explicit,
+by-hand numbering.
+
+Files that use cross-referencing (and almost all manuscripts do)
+need to be processed through \revtex\ at least twice to
+ensure that the tags have been properly linked to appropriate numbers.
+If any tags are added in subsequent editing sessions,
+\LaTeX{} will display a warning message in the log file that ends with
+\texttt{... Rerun to get cross-references right}.
+Running the file through \revtex\ again (possibly more than once) will
+resolve the cross-references. If the error message persists, check
+the labels; the same \marg{key} may have been used to label more than one
+object.
+
+Another \LaTeX\ warning is \texttt{There were undefined references},
+which indicates the use of a key in a \cmd\ref\ without ever
+using it in a \cmd\label\ statement.
+
+\revtex{} performs autonumbering exactly as in standard \LaTeX.
+When the file is processed for the first time,
+\LaTeX\ creates an auxiliary file (with the \file{.aux} extension) that
+records the value of each \meta{key}. Each subsequent run retrieves
+the proper number from the auxiliary file and updates the auxiliary
+file. At the end of each run, any change in the value of a \meta{key}
+produces a \LaTeX\ warning message.
+
+Note that with footnotes appearing in the bibliography, extra passes
+of \LaTeX\ may be needed to resolve all cross-references. For
+instance, putting a \cmd\cite\ inside a \cmd\footnote\ will require at
+least three passes.
+
+Using the \classname{hyperref} package to create hyperlinked PDF files
+will cause reference ranges to be expanded to list every
+reference in the range. This behavior can be avoided by using the
+\classname{hypernat} package available from \url{www.ctan.org}.
+
+\subsection{Acknowledgments}
+Use the \env{acknowledgments} environment for an acknowledgments
+section. Depending on the journal substyle, this element may be
+formatted as an unnumbered section titled \textit{Acknowledgments} or
+simply as a paragraph. Please note the spelling of
+``acknowledgments.''
+\begin{verbatim}
+\begin{acknowledgments}
+The authors would like to thank...
+\end{acknowledgments}
+\end{verbatim}
+
+\subsection{Appendices}
+The \cmd\appendix\ command signals that all following sections are
+appendices, so \cmd\section\marg{title text} after \cmd\appendix\ will set
+\marg{title text} as an appendix heading (an empty \marg{title text}
+is permitted). For a single appendix, use a
+\cmd\appendix\verb+*+ followed by \cmd\section\marg{title text}
+command to suppress the appendix letter in the section heading.
+
+\subsection{\label{sec:lineno}Line numbering}
+\revtex~4.2 provides the \classoption{linenumbers} class option to enable line numbering. While it is
+possible to directly call in the \classname{lineno.sty}, using the class option ensures
+that the default parameters needed to properly typeset the line numbers are set up correctly. It is
+still possible for authors to override parameters such as \cmd\linenumbersep\ as usual, however.
+
+\section{Math and equations}\label{sec:math}
+
+\subsection{Math in text}
+
+Not surprisingly, \revtex\ uses the \TeX\ math \verb+$+ delimiters
+for math embedded in text. For example,
+\verb|$a^{z}$| gives $a^{z}$. Within math mode, use
+\verb+^+\marg{math} for superscripts and
+\verb+_+\marg{math} for subscripts. If the braces after the
+\verb+^+ are omitted, \TeX{} will
+superscript the next \emph{token} (generally a single character or
+command). Thus it is safest to use explicit braces \verb+{}+.
+
+As with text, math should not require extensive explicit vertical or
+horzontal motion commands, because \TeX\ calculates math spacing
+itself automatically. In particular, explicit spacing around
+relations (e.g., $=$) or operators (e.g., $+$) should be
+unnecessary. These suggestions notwithstanding, some fine-tuning of
+math is required in specific cases, see Chapter~18 in the \TeX
+book\cite{TeXbook}.
+
+\subsection{Text in math}\label{sec:textinmath}
+
+There are times when normal, non-italic text needs to be inserted
+into a math expression. The \cmd\text\marg{text} command is the
+preferred method of accomplishing this. It produces regular text
+\emph{and} scales correctly in superscripts:
+\verb+$y=x \text{ for } x_{\text{e-p}}$+ gives
+``$y=x \text{ for } x_{\text{e-p}}$''. To use the \cmd\text\ command,
+the \classname{amsmath} package must be loaded: include a
+\cmd\usepackage\aarg{\classname{amsmath}} command in the document
+preamble or use the class option \classoption{amsmath}. Please note
+that \revtex~4.2 requires version 2.0 or higher of \classname{amsmath}.
+
+Other common alternatives may be less desirable. Using the standard
+\LaTeXe\ \cmd\mbox\marg{text} will give normal text, including a hyphen,
+but will not scale correctly in superscripts:
+\verb+$x_{\mbox{e-p}}$+ gives ``$x_{\mbox{e-p}}$''.
+The \cmd\rm\ command
+only switches to Roman font for math letters. It does not, for
+example, handle hyphens correctly:
+\verb+$$x_{\rm{e-p}}$+ gives ``$x_{\rm e-p}$''. But note that with
+\cmd\textrm{}, it does work: \verb+$x_{\textrm{e-p}}$+ gives ``$x_{\textrm{e-p}}$''.
+
+\subsection{Displayed equations}\label{sec:dispmath}
+
+Equations are set centered in the column width or flush left depending
+on the selected journal substyle.
+
+For the simplest type of displayed equation, a numbered, one-line
+equation, use the \env{equation} environment.
+\revtex\ takes care of the equation number%
+---the number will be set below the equation if necessary.
+Use \cmd\[\dots\cmd\] for a single, one-line unnumbered display equation.
+
+Use the \env{eqnarray} environment when more than one consecutive
+equation occurs, putting each equation in a separate row of the
+environment, and using \cmd\nonumber\ before the row end (\cmd\\) to
+suppress the equation number where necessary. If the equations are
+related to each other, align each on the respective relation operator
+(such as $=$).
+
+When an equation is broken over lines or is continued over multiple
+relation operators, it is called a multi-line or continued equation,
+respectively; here, too, use the \env{eqnarray} environment.
+
+For a continued equation, align each row on the relation operator just
+as with multiple equations, and use the \cmd\nonumber\ command to
+suppress auto-numbering on broken lines. Also, use the starred form
+of the row end (\cmd\\\verb+*+) to prevent a pagebreak at that
+juncture.
+
+Short displayed equations that can appear together on a single line
+separated by \cmd\qquad\ space may be placed in a single
+\env{equation} environment.
+
+As explained in Section~\ref{sec:widetext}, occasionally in two-column
+mode a long equation, in order to fit it in the narrow column width,
+would need to be broken into so many lines that it would affect
+readibility. Set it in a wide column using the \env{widetext}
+environment. Then return to the normal text width as soon as
+possible.
+
+The sample file \file{apssamp.tex} illustrates how to obtain each of
+the above effects.
+
+\subsection{Numbering displayed equations}
+
+\revtex~4.2 automatically numbers equations.
+For single-line and multi-line equations, use the
+\env{equation} and \env{eqnarray} environments as described above.
+For unnumbered single-line equations, use the \verb+\[+\dots\verb+\]+
+construction. The command \cmd\nonumber\ will suppress the numbering
+on a single line of an
+\env{eqnarray}.
+For a multi-line equation with no equation numbers at all,
+use the \env{eqnarray*} environment.
+
+A series of equations can be a labeled with a lettered sequence,
+e.g., (3a), (3b), and (3c), by
+putting the respective \env{equation} or \env{eqnarray} environment within a
+\env{subequations} environment.
+The \classname{amsmath} package (can be loaded with the
+\classoption{amsmath} class option) is required for this.
+
+Use the command \cmd\tag\marg{number} to produce an idiosyncratic
+equation number: $(1')$, for example. Numbers assigned by \cmd\tag\
+are completely independent of \revtex's automatic numbering. The
+package \classname{amsmath} is required for using the \cmd\tag\
+command. Please
+note that the use of the \texttt{tag} command may conflict with the use of the \classoption{hyperref} package
+due an incompatibility between \classoption{amsmath} and \classoption{hyperref}.
+
+To have \revtex{} reset the equation numbers at the start of each section,
+use the \classoption{eqsecnum} class option in the document preamble.
+
+See the sample file \file{apssamp.tex} for some examples.
+
+\subsection{Cross-referencing displayed equations}
+
+To refer to a numbered equation, use
+the \cmd\label\marg{key} and \cmd\ref\marg{key} commands.
+The \cmd\label\marg{key} command is used within the referenced equation
+(on the desired line of the \env{eqnarray}, if a multi-line equation):
+\begin{verbatim}
+\begin{equation}
+ A=B \label{pauli}
+\end{equation}
+ ... It follows from Eq.~(\ref{pauli})
+that this is the case ...
+\begin{eqnarray}
+ A & = &B,\label{pauli2}\\
+ A'& = &B'
+\end{eqnarray}
+\end{verbatim}
+gives
+\begin{equation}
+A=B \label{pauli}
+\end{equation}
+ ... It follows from Eq.~(\ref{pauli})
+that this is the case ...
+\begin{eqnarray}
+A & = &B,\label{pauli2}\\
+A'& = &B'
+\end{eqnarray}
+
+Please note the parentheses surrounding the \cmd\ref\ command.
+These are \emph{not} provided automatically and, thus, must be
+explicitly incorporated.
+
+Numbers produced with \cmd\tag\ can also be cross-referenced by adding
+a \cmd\label\ command after the \cmd\tag\ command.
+
+Using a \cmd\label\ after \envb{subequations} to reference the
+\emph{general} number of the equations in the
+\env{subequations} environment. For example, if
+\begin{verbatim}
+\begin{subequations}
+ \label{allequations} % notice location
+ \begin{eqnarray}
+ E&=&mc^2,\label{equationa}
+ \\
+ E&=&mc^2,\label{equationb}
+ \\
+ E&=&mc^2,\label{equationc}
+ \end{eqnarray}
+\end{subequations}
+\end{verbatim}
+%
+gives the output
+\begin{subequations}
+\label{allequations} % notice location
+\begin{eqnarray}
+E&=&mc^2,\label{equationa}
+\\
+E&=&mc^2,\label{equationb}
+\\
+E&=&mc^2,\label{equationc}
+\end{eqnarray}
+\end{subequations}
+%
+then \verb+Eq.~(\ref{allequations})+ gives ``Eq.~(\ref{allequations})''.
+
+{\bf Note:} incorrect cross-referencing will result if
+\cmd\label\ is used in an unnumbered single-line equation
+(i.e., within the \verb+\[+ and \verb+\]+ commands),
+or if \cmd\label\ is used on a line of an eqnarray that is not being numbered
+(i.e., a line that has a \cmd\nonumber).
+
+\subsection{Using the AMS packages \classoption{amsfonts},
+\classoption{amssymb}, and \classoption{amsmath}}\label{AMS}
+
+The American Mathematical Society's AMS-\LaTeX\ packages provided extra
+fonts, symbols, and math markup that are quite convenient. \revtex~4.2
+supports the use of these packages directly. To use the \classoption{amsfonts},
+\classoption{amssymb}, and \classoption{amsmath} class options,
+AMS-\LaTeX\ (and perhaps the additional AMS fonts) will need to be
+installed. Please note that \revtex~4.2 requires version 2.0 or higher
+of AMS-\LaTeX. These packages can be downloaded from
+\url{http://www.ams.org/tex/}.
+
+There are two class options for accessing the AMS fonts:
+\classoption{amsfonts} and \classoption{amssymb}.
+The \classoption{amsfonts} option defines the \cmd\mathfrak\ and
+\cmd\mathbb\ commands to switch to the Fraktur and
+Blackboard Bold fonts, respectively.
+These fonts are selected with the \cmd\mathfrak\ and \cmd\mathbb\
+font-switching commands:
+\verb+${\mathfrak{G}}$+ gives a Fraktur ``$\mathfrak{G}$''
+and \verb+${\mathbb{Z}}$+ gives a Blackboard Bold ``$\mathbb{Z}$''.
+\revtex{} does not currently support the use of the extra Euler fonts
+(the AMS fonts starting with \texttt{eur} or \texttt{eus}) or the
+Cyrillic fonts (the AMS fonts starting with \texttt{w}).
+
+The \classoption{amssymb} class option gives all the font
+capabilities of the
+\classoption{amsfonts} class option and further defines the commands
+for many commonly used math symbols. These symbols will scale
+correctly in superscripts and other places. See the AMS-\LaTeX\
+documentation for the complete list of symbols available.
+
+\subsection{Bold symbols in math}\label{sec:bboxamsfonts}
+
+\revtex~4.2 uses the standard \LaTeXe\ Bold Math (\classname{bm}) package as the
+basis for creating bold symbols in math mode. As usual, this requires
+an explicit \cmd\usepackage\aarg{\classname{bm}} in the document
+preamble. The command
+\cmd\bm\marg{symbol} makes \marg{symbol} bold in math mode, ensuring
+that it is the correct size, even in superscripts. If the correct font
+in the correct size is not available then result is the \marg{symbol}
+set at the
+correct size in lightface and a \LaTeXe\ warning that says
+``\texttt{No boldmath typeface in this size}\dots''. Most bold special
+characters will require that the AMS fonts be installed and the
+\classoption{amsfonts} class option be invoked.
+
+\cmd\bm\ is the proper means to get bold Greek characters---upper- and
+lowercase---and other symbols.
+The following will come out bold with \cmd\bm:
+normal math italic letters, numbers,
+Greek letters (uppercase and lowercase),
+small bracketing and operators, and \cmd\mathcal. Fraktur
+characters will come out bold in a \cmd\bm; however, Blackboard Bold
+requires using the \cmd\mathbb\ command rather than \cmd{\bm}.
+The \classoption{amsfonts} option adds support for bold math
+letters and symbols in smaller sizes and in superscripts when a
+\cmd\bm\marg{symbol} is used.
+For example, \verb+$\pi^{\bm{\pi}}$+ gives a bold
+lowercase pi in the superscript position: $^{\pi\bm{\pi}}$.
+
+Note that \cmd\bm\marg{math} is a fragile command and, thus, should be
+preceded by \cmd\protect\ in commands with moving arguments.
+
+\section{Footnotes}
+\LaTeX's standard \cmd\footnote\ command is available in
+\revtex~4.2. The footnote text can either appear at the bottom of a page or
+as part of the bibliography. This choice can be controlled by two class options:
+\classoption{footinbib} and \classoption{nofootinbib}. \revtex~4.2
+defaults to the former. Specific journal options may select a
+different value than the default.
+
+Please note that even if Bib\TeX\ is not being used for the references, you
+may have to run Bib\TeX\ if you are using footnotes without the \classoption{nofootinbib} option.
+The log file will contain errors about missing references such as \texttt{Note1} in this case and a file ending in
+\texttt{Notes.bib} will have been produced during the processing of the \TeX\ file.
+
+Note that in the latter case, the
+argument of the
+\cmd\footnote\ command is a moving argument in the sense of the \LUG,
+Appendix~C.1.3: any fragile command within that argument must be
+preceded by a \cmd\protect\ command.
+
+The \cmd\footnote\ macro \emph{should not} be used in the front
+matter for indicating author/affiliation relationships or to provide
+additional information about authors (such as an e-mail
+address). See Section~\ref{sec:footau} for the proper way to do
+this.
+
+Finally, footnotes that appear in tables behave differently. They
+will be typeset as part of the table itself. See
+Section~\ref{sec:tablenote} for details.
+
+\section{Citations and References}\label{sec:endnotes}
+
+\revtex~4.2 adds significant new functionality to \revtex~4's
+typesetting of citations and references. The new functionality is
+designed to make it easier to use Bib\TeX\ and produce the desired output
+in the reference section without having to edit Bib\TeX's output. The new features include:
+\begin{itemize}
+\item Endnotes created with the \cmd\footnote\ command are automatically interleaved with the bibliographic references. \revtex~4 would typeset all endnotes at the end of the bibliography.
+\item Combining multiple references automatically into a single entry in the bibliography. \revtex~4 required by-hand editing of Bib\TeX\ output. This is achieved by prepending an asterisk (*) to the reference's \textit{key} in the \cmd\cite\ command. \verb+\cite{{key1,*key2}+ would make a single entry in the bibliography by combining into one \cmd\bibitem\ the entries from the \texttt{.bib} file with keys \textit{key1} and \textit{key2}. See Section~\ref{sec:multiple} for more details.
+\item Text can be prepended or appended to an entry in the bibliography. \revtex~4 required by-hand editing of the Bib\TeX\ output. See Section~\ref{sec:prepend} for an example of how to do this.
+\end{itemize}
+
+Proper formatting of references requires Patrick Daly's \classname{natbib} citation package. \BibTeX\ style files
+for APS and AIP journals are created using his \classname{custom-bib} tool kit. From an author's point of view, all this means is that a proper
+\revtex~4.2 installation requires having \classname{natbib} (version 8.31a
+or higher) installed. It also means that the full set of
+\classname{natbib} functionality is available from within \revtex~4.2
+(but see the \textit{APS Author Guide for \revtex~4.2} and \textit{Author's Guide to AIP Substyles for \revtex~4.2} for restrictions if
+submitting to an APS or AIP journal). The \classname{natbib} documentation contains many examples; see in
+particular the \verb+natnotes.tex+ file for a convenient summary. Please also note that \classname{natbib 8.3} and later now gives an error (rather than merely a warning as in earlier versions) if you try to use a Bib\TeX\ file that isn't compatible with author-year style citations with a journal style that requires author-year citations (such as \textit{Reviews of Modern Physics}).
+
+\subsection{Citing a reference}
+As in standard \LaTeX, references are cited in text using the
+\cmd\cite\marg{key} command and are listed in the bibliography using
+the \cmd\bibitem\marg{key} command. The \cmd\cite{} macro enables
+\revtex~4.2 to automatically number the references in the manuscript.
+
+A typical example might be:
+\begin{verbatim}
+String theory\cite{GSW} attempts to
+provide a theory of everything.
+\end{verbatim}
+The corresponding \cmd\bibitem{} would be:
+\begin{verbatim}
+\bibitem{GSW} M.~Greene, J.~Schwarz, and
+E.~Witten, \textit{Superstring Theory:
+Introduction}, (Cambridge University
+Press, London, 1985).
+\end{verbatim}
+
+Journals differ in how the \cmd\cite\ will be displayed. Most APS journals
+display the citation in-line, as a number, enclosed in square brackets,
+\textit{e.g.}, ``String theory[1] attempts\dots.'' Other journals
+may instead use a number in a superscript: ``String theory$^{1}$ attempts\dots.''
+Selecting the journal substyle using a class option will invoke the appropriate style.
+In journal substyles using superscripts,
+the macro the \cmd\onlinecite\marg{key} is necessary to get the number
+to appear on the baseline.
+For example, ``String theory (see, for example,
+\verb+Ref.~\onlinecite{GSW}+)'' will give the output
+``String theory (see, for example, Ref.~1).''
+
+The \cmd{\onlinecite} command has the same semantics as
+\classname{natbib}'s \cmd{\citealp} command.
+
+A \cmd\cite\ command with multiple keys is formatted with consecutive
+reference numbers collapsed; e.g., [1,2,3,5] will be output as
+[1--3,5]. To split the list over more than one line, use
+a \verb+%+ character immediately following a comma:
+\begin{verbatim}
+. . . \cite{a,b,c,d,e,f,%
+g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z}
+\end{verbatim}
+The \verb+%+ avoids unwanted spaces.
+
+\subsection{Author/Year (Non-numeric) Citations}
+
+\textit{Reviews of Modern Physics} uses a citation style based on the
+first author's last name and the year of the reference rather than a
+simple number. Support for this style of citing references is the
+primary reason \revtex~4.2 uses the \classname{natbib}
+package. \classname{natbib} uses an optional argument to the
+\cmd\bibitem\ macro to specify what text to use for the \cmd\cite\
+text:
+\begin{quote}
+\cmd\bibitem\verb+[+\meta{short-name}\verb+(+\meta{year}\verb+)+\meta{long-name}\verb+]+
+\end{quote}
+where \meta{short-name} is the author name used in a parenthetical citation,
+\meta{long-name} that used in a textual citation, and
+\meta{year} is the year. More concretely, the \cmd\bibitem\ example
+above would appear as
+\begin{verbatim}
+\bibitem[Greene et al.(1985)Green,
+Schwarz, and Witten]{GSW}
+M.~Greene, J.~Schwarz, and E.~Witten,
+\textit{Superstring Theory},
+(Cambridge Press, London, 1985).
+\end{verbatim}
+
+When the citation constitutes part of the grammar of the sentence,
+the \cmd\textcite\marg{key} command may be used (analogous to the
+\cmd\onlinecite\ command above). Both \cmd\textcite\ and
+\cmd\onlinecite\ are built upon \classname{natbib}'s rich repertoire of
+macros (\cmd\citep{}, \cmd\citet{}, etc.). These macros are available in
+\revtex~4.2; however, APS authors must follow the
+\textit{APS Author Guide for \revtex~4.2}
+guidelines regarding \classname{natbib}'s macros.
+
+\subsection{Combined Author/Year and Numeric Citations}
+
+AIP's \textit{Journal of Mathematical Physics} uses a combined author/year and numerical citation style. \revtex~4.2 supports this referencing style. Please see the \textit{Author's Guide to AIP Substyles for \revtex~4.2} for more information about this style.
+
+\subsection{\label{sec:use-bib}Using Bib\TeX}
+
+The \cmd\bibitem{} entries can be coded by hand as above, of course, but the
+use of \BibTeX\ with the new style files provided with \revtex~4.2 makes
+it particularly simple to generate marked-up references that can, for
+instance, take advantage of packages like
+\classname{hyperref} for linking. They also save the trouble of having
+to specify formatting like the italics for the book title in the above
+example. And, for those wishing to use author/year citations, \BibTeX\
+will automatically generate the appropriate optional arguments for the
+\cmd\bibitem\ commands.
+
+\BibTeX\ is an adjunct to \LaTeX\ that aids in the
+preparation of bibliographies. \BibTeX\ allows authors to build up a
+database or collection of bibliography entries that may be used for many
+manuscripts. A \BibTeX\ style file then specifies how to transform the
+entries into a proper \cmd\bibitem{} for a particular journal. Here we
+give a brief summary of how to get started with \BibTeX. More details can be
+found in the LaTeX books listed in the references.
+
+Selecting a journal style by using an appropriate class option will
+automatically select the correct \BibTeX\ style file from those included in
+\revtex~4.2. Five basic \BibTeX\ style files are included: \file{apsrev4-2.bst} (APS journals using a numeric citation style, \textit{i.e.}, all but RMP), \file{apsrmp4-2.bst} (author/year style citations for RMP),
+\file{aipauth4-2.bst} (AIP journal using an author/year citation style), \file{aipnum4-2.bst} (AIP journals using a numeric citation style) and \file{aapmrev4-2.bst} for AAPM journals. The selection can be overridden by specifying an
+alternative \file{.bst} file using the standard \LaTeXe
+\cmd\bibliographystyle\ macro. This must appear in the preamble
+before the \envb{document} line in \revtex~4.2 (this differs from
+standard \LaTeX).
+
+The \BibTeX\ database files will contain entries such as:
+\begin{verbatim}
+@Book{GSW,
+ author=``M. Greene, J. Schwarz,
+ E. Witten'',
+ title=``Superstring theory:
+ Introduction'',
+ publisher=``Cambridge University
+ Press'',
+ address=``London'',
+ year=``1985''
+}
+\end{verbatim}
+There are entry formats for articles, technical reports, e-prints,
+theses, books, proceedings, and articles that appear in books or
+proceedings. The styles provided with
+\revtex~4.2 also allows URL's and e-print identifiers to be specified
+for any of the different entry types. There is also an additional
+``collaboration'' field that can be used in addition to ``author'.'
+
+To actually create the bibliography in the manuscript, the
+\cmd\bibliography\marg{bib files} macro is used.
+Here \meta{bib files} is a comma-separated list of \BibTeX\ bibliography
+database files, each with the \file{.bib} extension. The
+\cmd\bibliography\ macro should be placed at the location where the
+references are to appear (usually after the main body of the
+paper). When the manuscript is processed with \LaTeX\ for the first
+time, the keys corresponding for the \cmd\cite{} macros used in the
+manuscript are written out to the \file{.aux} file. Then \BibTeX\ should
+be run (if the manuscript is called \file{paper.tex}, the command would
+be \verb+bibtex paper+. This will produce a \file{.bbl} file containing all
+of the \cmd\bibitem{}'s for the manuscript. Subsequent runs of \LaTeXe\
+will call this file in to resolve the references. \LaTeXe\ should be run
+repeatedly until all references are resolved.
+
+The \BibTeX-produced \cmd\bibitem{}'s created using the \revtex\ style files appear considerably more complex than the example given
+above. This is because the style files add in \cmd\bibinfo{},
+\cmd\bibnamefont{}, \cmd\eprint{}, and \cmd\url{} macros for
+specifying additional formatting and tagging. The \cmd\bibinfo\ macro
+is mostly a do-nothing macro that serves merely to tag the information with
+the field information from the original entry in the \BibTeX\ database.
+The \cmd\eprint\ and \cmd\url\ macros can be used to create the
+appropriate hyperlinks in target formats such as PDF.
+
+For more information on using \BibTeX\ with \LaTeX, see Sections~4.3.1
+and~C.11.3 of the \LUG\cite{LaTeXman}, Section~13.2 of \cite{Compan},
+or the online \BibTeX\ manual \file{btxdoc.tex} from
+\url{http://www.ctan.org/tex-archive/biblio/bibtex/distribs/doc/}.
+
+\subsubsection{\texttt{arXiv.org} support}
+
+\revtex~4.2 supports citing e-prints from \texttt{arXiv.org} For instance, the \texttt{.bib} entry
+\begin{verbatim}
+@Unpublished{Ginsparg:1988ui,
+ author = "Ginsparg, Paul H.",
+ title = "{Applied Conformal Field Theory}",
+ year = "1988",
+ eprint = "hep-th/9108028",
+ archivePrefix = "arXiv",
+ SLACcitation = "%%CITATION=HEP-TH/9108028;%%"
+}
+\end{verbatim}
+will include the arXiv.org e-print identifier as \texttt{arXiv:hep-th/9108028} and hyperlink it (if using \texttt{hyperref}). The newer format for arXiv identifiers with primary classifications will produce appropriate output For example,
+
+\begin{verbatim}
+@Unpublished{Ginsparg:2014,
+ author = "Ginsparg, Paul",
+ title = "{Kenneth G. Wilson: Renormalized After-Dinner Anecdotes}",
+ year = "2014",
+ eprint = "1407.1855",
+ archivePrefix = "arXiv",
+ primaryClass = "physics.hist-ph",
+}
+\end{verbatim}
+will generate \texttt{arXiv:1407.1855 [physics.hist-ph]} and hyperlink it.
+
+\subsubsection{\texttt{noeprint} option}
+In the \revtex~4.2 Bib\TeX\ style files, the behavior of the \texttt{noeprint} option was changed to only suppress the arXiv identifiers for journal references, but keep them for e-print references.
+
+\subsubsection{\label{sec:datacitations}Citing data sets with a DOI}
+Bib\TeX\ styles in \revtex~4.2 add support for citing data sets using the new Bib\TeX\ type \texttt{@dataset}:
+
+\begin{verbatim}
+@dataset{haigh:2016,
+ author = "Haigh, J. A. and Lambert, N. J. and
+ Sharma, S. and Blanter, Y. and
+ Bauer, G. E. W. and Ramsay, A. J.",
+ year = "2018",
+ title = "{Data from Figures in``Selection rules
+ for cavity-enhanced Brillouin light scattering
+ from magnetostatic modes" [Data set]}",
+ doi = "10.5281/zenodo.1284434",
+ note = "{Zenodo}"
+}
+\end{verbatim}
+This results in the formatted reference: ``J. A. Haigh, N. J. Lambert, S. Sharma, Y. Blanter, G. E. W. Bauer, and A. J. Ramsay, Data from Figures in ``Selection
+rules for cavity-enhanced Brillouin light scattering from magnetostatic modes" [Data set], 10.5281/zenodo.1284434 (2018),
+Zenodo."
+
+This is primarily intended for data sets that have a DOI assigned to them.
+
+\subsubsection{\label{sec:doiref}Journal references with only DOIs}
+Some journals have moved to using only a volume and DOI to identify an article and do not assign page numbers or article identifiers. In the \texttt{apsrev.bst} Bib\TeX\ style file used for the \textit{Phys. Rev.} journals, If the \texttt{pages} field is absent from an entry in the \texttt{bib} file, but the \texttt{doi} field is present, the DOI will be explicitly displayed and linked in the formatted reference.
+
+\subsubsection{\label{sec:jhep}Journals that use the year and issue for unique citations}
+The \texttt{apsrev.bst} style used for \textit{Phys. Rev.} journals now includes support for four journals that use the year in place of a volume and require an explicit issue to uniquely cite a paper:
+
+\begin{itemize}
+ \item J. High Energy Phys.
+ \item J. Cosmol. Astropart. Phys.
+ \item J. Instrum.
+ \item J. Stat. Mech.: Theory Exp.
+ \end{itemize}
+
+ The Bib\TeX\ entry must \textbf{exactly} match one of the these four abbreviated journal names or use the corresponding macro, \texttt{jhep}, \texttt{jcap}, \texttt{jinst}, or \texttt{jstat}, resp., to invoke the proper formatting. For example:
+
+\begin{verbatim}
+@Article{Cotogno2017,
+ author="Cotogno, Sabrina and van Daal, Tom
+ and Mulders, Piet J.",
+ title="Positivity bounds on gluon {TMDs}
+ for hadrons of spin $\le$ 1",,
+ journal=jhep,
+ year="2017",
+ month="Nov",
+ day="28",
+ volume="2017",
+ number="11",
+ pages="185",
+ doi="10.1007/JHEP11(2017)185",
+ url="https://doi.org/10.1007/JHEP11(2017)185"
+}
+\end{verbatim}
+will be formatted as ``S. Cotogno, T. van Daal, and P. J. Mulders, Positivity bounds on gluon TMDs for hadrons of spin $\le$ 1, J. High Energy Phys. 2017 (11), 185."
+
+\subsection{\label{sec:multiple}Multiple references in a single bibliography entry}
+\revtex~4.2 allows multiple references within a single bibliography entry when using Bib\TeX. This done by using a starred (*) argument to the \cmd\cite\ command, and it requires a compatible version of \texttt{natbib} and the \texttt{bst} files that come with \revtex~4.2. To combine multiple references into a single \cmd\bibitem, precede the second, third, etc. citation keys in the \cmd\cite\ command with an asterisk (*). For example \verb+\cite{bethe, *feynman, *bohr}+ will combine the \cmd\bibitem\relax s with keys \texttt{bethe}, \texttt{feynman}, and \texttt{bohr} into a single entry in the bibliography separated by semicolons.
+
+\subsection{\label{sec:prepend}Prepending and/or appending text to a citation}
+The expanded syntax for the \cmd\cite\ command argument can also be used to specify text before and/or after a citation. For instance, a citation such as:
+\begin{verbatim}
+[19] A similar expression was derived in
+A. V. Andreev, Phys. Rev. Lett. 99, 247204
+(2007) in the context of carbon nanotube
+p-n junctions. The only difference is that no
+integration over ky is present there.
+\end{verbatim}
+may be created by the following \cmd\cite\ command:
+\begin{verbatim}
+\cite{*[{A similar expression was derived
+in }] [{ in the context of carbon nanotube
+p-n junctions. The only difference is that
+no integration over ky is present
+there.}] andreev2007}
+\end{verbatim}
+Please note the use of curly braces to enclose the text within the square brackets as well as the spaces next to the brackets.
+
+
+
+\section{Figures and Artwork}\label{sec:figures}
+\subsection{\texttt{figure} environment}
+
+Figures may be included into a \revtex~4.2 manuscript by using the
+standard \LaTeXe\ macros. It should be noted that \LaTeXe\ includes
+several powerful packages for including the files in various
+formats. The two main packages are \classname{graphics} and
+\classname{graphicx}. Both offer a macro called
+\cmd\includegraphics\oarg{args}\marg{filename};
+they mainly differ in how arguments for
+controlling figure scaling, translation, and orientation
+are specified. For more information on the enhancements of the \classname{graphicx} package,
+see \cite{CompanG} or the guide \file{grfguide.pdf} available at
+\url{http://www.ctan.org/tex-archive/macros/latex/required/graphics/}.
+\revtex~4.2 no longer has the \classoption{epsf} class option, though
+the \classname{epsfig} package provides a similar interface.
+
+
+The \env{figure} environment should be used to add a caption to the figure and
+to allow \LaTeX\ to number and place the figures where they fit best.
+\LaTeX\ will label and automatically number the captions FIG.~1,
+FIG.~2, etc. For example:
+\begin{verbatim}
+\begin{figure}
+ \includegraphics{fig1.eps}
+ \caption{\label{fig1}Text of first caption.}
+\end{figure}
+\end{verbatim}
+Note how the \cmd\label\marg{key} command is used to cross-reference
+figures in text. The \cmd\label\marg{key} command should be inserted
+inside the figure caption. As usual, the \cmd\ref\marg{key} macro can
+then by used to refer to the label: ``As depicted in
+FIG.\verb+~\ref{fig1}+\dots''.
+
+Figures are normally set to the width of the column in
+which they are placed. This means that in two-column mode, the figure
+will be placed in a single, narrow column. For wide figures, the
+\cmd\figure\verb+*+ environment should be used
+instead. This will place the figure across both columns (the figure
+usually will
+appear either at the top or the bottom of the following page).
+
+
+Captions less than one line long are centered under the figure,
+otherwise they span the width of the figure.
+
+Note that is unnecessary (and undesirable) to use explicit centering
+commands inside the float environments.
+
+\subsection{\texttt{video} environment}
+Papers often refer to multimedia material such as videos. The \texttt{video} environment is identical to the \texttt{figure} environment, but the caption will be labeled as a \textbf{Video} (with its own counter independent of figures). A URL can also be specified so that the caption label can be linked to the online video (if using the \texttt{hyperref} package). The included graphic (using \cmd\includegraphics\ from the \texttt{graphics} or \texttt{graphicx} package) would be a representation frame from the video. A \texttt{\cmd\listofvideos} is also provided. For example:
+\begin{verbatim}
+\begin{video}
+\includegraphics{videoframe.jpg}
+\setfloatlink{http://some.video.com/fun.mov}
+\caption{\label{vid:interest}This is a video
+of something fun.}
+\end{video}
+\end{verbatim}
+There is also a corresponding \cmd\listofvideos\ command.
+
+\section{Tables}\label{sec:tables}
+
+Tables are very similar to figures. They should be input using the
+\env{table} environment as detailed below, and
+\LaTeX\ will label and number the captions TABLE~1, TABLE~2, etc.
+(or in whatever format required by the chosen journal
+substyle). Tables without captions won't be numbered.
+
+Each table must begin with \envb{table}, end with \enve{table}. A
+caption can be specified using the \cmd\caption\marg{text} command.
+Captions less than one line long are centered under the figure,
+otherwise they span the width of the figure.
+To refer to the table via cross-referencing, a \cmd\label\marg{key}
+command should appear within the \cmd{\caption}. Use the
+\cmd\ref\marg{key} command to cite tables in text. The \env{table}
+environment will set the table to the width of the column. Thus, in
+two-column mode, the table will be confined to a single column. To set a
+table to the full width of the page, rather than the column, use the
+\env{table*} environment.
+
+The heart of the table is the
+\env{tabular} environment. This will behave for the most part as in
+standard \LaTeXe\ (please refer to Section~3.6.3 and Appendix~C.10.2 of the
+\LUG{} for more details about the \env{tabular} environment).
+Note that \revtex~4.2 no longer automatically adds double (Scotch) rules
+around tables. Nor does the \env{tabular} environment set various
+table parameters for column spacing as before. Instead, a new
+environment \env{ruledtabular} provides this functionality. This
+environment should surround the \env{tabular} environment:
+\begin{verbatim}
+\begin{table}
+\caption{\label{<key>}....}
+\begin{ruledtabular}
+\begin{tabular}
+...
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+\end{verbatim}
+
+A basic table looks as follows:
+\begin{verbatim}
+\begin{table}
+\caption{\label{tab:ex}Text of table caption.}
+\begin{ruledtabular}
+\begin{tabular}{ll}
+ Heading 1 & Heading 2\\
+ Cell 1 & Cell 2\\
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+\end{verbatim}
+
+The \env{quasitable} environment is no longer in \revtex~4.2. The
+standard \env{tabular} environment can be used instead because it
+no longer puts in the double rules.
+
+\subsection{Aligning on a decimal point}
+Numerical columns should align on the decimal point (or
+decimal points if more than one is is present). This is accomplished
+by again using a standard \LaTeXe\ package, \classname{dcolumn} which
+must be loaded in the manuscript's preamble:
+\begin{verbatim}
+\usepackage{dcolumn}
+\end{verbatim}
+Once this package is loaded, the column specifier `\texttt{d}' can be
+used in the table's \env{tabular}\marg{preamble} enviroment preamble.
+The `\texttt{d}' should be used for simple numeric data with a single
+decimal point.
+%
+The entry of a \texttt{d} column is typeset in math mode; do not
+insert any \verb+$+ math delimiters into a `\texttt{d}' column. Items
+without a decimal point are simply set in math mode, centered. If
+text is required in the column, use \cmd\text\ or \cmd\mbox\ as
+appropriate. If multiple decimal points are present then the last is
+used for alignment. To escape from the `\texttt{d}' column use
+\cmd\multicolumn\ as usual. See the sample file \file{apssamp.tex} for examples.
+
+\subsection{Footnotes in Tables}\label{sec:tablenote}
+
+Footnotes in a table are labeled \emph{a}, \emph{b}, \emph{c},
+etc. They can be specified by using the \LaTeX\ \cmd\footnote\
+command. Furthermore,
+\cmd\footnotemark\ and \cmd\footnotetext\ can be used so that multiple entries
+can to refer to the same footnote. The footnotes for a table are typeset
+at the bottom of the table, rather than at the bottom of the page or
+at the end of the references. The arguments for \cmd\footnotemark\ and
+\cmd\footnotetext\ should be numbers 1, 2, \dots. The journal style
+will convert these to letters. See sample file \file{apssamp.tex} for
+examples and explanations of use.
+
+\subsection{Dealing with Long Tables}
+By default, tables are set in a smaller size than the text body
+(\cmd\small). The \cmd\squeezetable\ declaration makes the table font
+smaller still (\cmd\scriptsize). Thus, putting the
+\cmd\squeezetable\ command before the \envb{table} line in a table
+will reduce the font size. If this isn't sufficient to fit
+the table on a page, the standard \LaTeXe\ \classname{longtable}
+package may be used. The scope of the
+\cmd\squeezetable\ command must be limited by enclosing it with a group:
+\begin{verbatim}
+\begingroup
+\squeezetable
+\begin{table}
+[...]
+\end{table}
+\endgroup
+\end{verbatim}
+
+Tables are normally set to the width of the column in
+which they are placed. This means that in two-column mode, the table
+will be placed in a single, narrow column. For wide tables, the
+\cmd\table\verb+*+ environment should be used
+instead. This will place the table across both columns (the table
+usually will
+appear either at the top or the bottom of the following page).
+
+
+To break tables across pages, \revtex~4.2 requires adding to the
+table a float placement option of [H] (meaning put the table ``here''
+and effectively ``unfloating'' the table) to the \envb{table}
+command. The commands \verb+\\*+ and \cmd{\samepage} can be used to
+control where the page breaks occur (these are the same as for the
+\env{eqnarray} environment).
+
+Long tables are more robustly handled by using the
+\classname{longtable.sty} package included with the standard \LaTeXe\
+distribution (put \verb+\usepackage{longtable}+ in the preamble). This
+package gives precise control over the layout of the table.
+The \revtex~4.2 package contains patches that enable the
+\classname{longtable} package to work in two-column mode. Of course, a
+table set in two-column mode needs to be narrow enough to fit within
+the column. Otherwise, the columns may overlap. \revtex~4.2 provides
+an additional environment \env{longtable*} which allows a longtable to
+span the whole page width. Currently, the \env{longtable*} and
+\env{ruledtabular} environments are incompatible. In order to get the
+double (Scotch) rule, it is necessary to add the \verb+\hline\hline+
+manually (or define \verb+\endfirsthead+ and \verb+\endlastfoot+
+appropriately). For more documentation on the \env{longtable}
+environment and on the package options of the
+\classname{longtable} package, please see the documentation available at
+\url{http://www.ctan.org/macros/latex/required/tools/longtable.dtx} or
+refer to \cite{Compan}.
+
+\section{Placement of Figures, Tables, and Other Floats}
+\label{sec:place}
+
+By default, figures and tables (and any other ``floating'' environments
+defined by other packages) float to the top or bottom of the page
+using the standard \LaTeX\ float placement mechanism. Initially, each
+\env{figure} or \env{table} environment should be put immediately
+following its first reference in the text; this will usually result in
+satisfactory placement on the page. An optional argument for either
+environment adjusts the float placement. For example:
+\begin{quote}
+\envb{figure}\oarg{placement}\\
+\dots\\
+\enve{figure}
+\end{quote}
+where \meta{placement} can be any combination of \verb|htbp!|, signifying
+``here'', ``top'', ``bottom'', ``page'', and ``as soon as possible'',
+respectively. The same placement argument may be added to a
+\envb{table}. For more details about float placement,
+see the instructions in the \LUG, Appendix~C.9.1.
+
+In two-column mode, a page may contain both a \env{widetext}
+environment and a float. \revtex~4.2 may not always be able to
+automatically put the float in the optimal place. For instance, a
+float may be placed at the bottom of a column just before the
+\env{widetext} begins. To workaround this, try moving the float
+environment below the \env{widetext} environment. Alternative
+\meta{placements} may also alleviate the problem.
+
+\env{figure} and \env{table} environments should not
+be enclosed in a \env{widetext} environment to make them span
+the page to accommodate wide figures or tables. Rather, the
+\env{figure*} or \env{table*} environments should be used instead.
+
+Sometimes in \LaTeX\ the float placement mechanism breaks down and a
+float can't be placed. Such a ``stuck'' float may mean that it and all
+floats that follow are moved to the end of the job (and if there are
+too many of floats, the fatal error \texttt{Too many unprocessed floats}
+will occur). \revtex~4.2 provides the class option
+\classoption{floatfix} which attempts to invoke emergency float
+processing to avoid creating a ``stuck'' float. \revtex~4.2 will provide
+a message suggesting the use of
+\classoption{floatfix}. If \classoption{floatfix} doesn't work or if
+the resulting positioning of the float is poor, the float should be
+repositioned by hand.
+
+\revtex~4.2 offers an additional possibility for placing the floats. By
+using the either the \classoption{endfloats} or the
+\classoption{endfloats*} class option all floats may be held
+back (using an external file) and then set elsewhere in the document
+using the the commands \cmd\printtables\ and \cmd\printfigures{},
+placed where the tables and figures are to be printed (usually at the
+end of the document). (This is similar to the standard
+\cmd\printindex\ command). Using a \texttt{*}-form of the commands
+(\cmd\printfigures\verb+*+ and
+\cmd\printtables\verb+*+) will begin the figures
+or tables on a new page. Alternatively, the option
+\classoption{endfloats*} may be used to change the behavior of the
+non-\texttt{*}-forms so that every float will appear on a separate
+page at the end.
+
+Without one of the \classoption{endfloats} class options, these float
+placement commands are silently ignored, so it is always safe to use
+them. If one of the \classoption{endfloats} class options is given,
+but the \cmd\printtables\ command is missing, the tables will be
+printed at the end of the document. Likewise, if \cmd\printfigures\ is
+missing, the figures will be printed at the end of the document.
+Therefore it is also safe to omit these commands as long as \revtex's
+default choices for ordering figures and tables are satisfactory.
+
+The \classoption{endfloats} option (or perhaps some journal substyle
+that invokes it), requires explicit \envb{figure}, \enve{figure},
+\envb{table}, and \enve{table} lines. In particular, do \emph{not}
+define typing shortcuts for table and figure environments, such as
+\begin{verbatim}
+\def\bt{\begin{table}}% Incompatible!
+\def\et{\end{table}}%
+\end{verbatim}
+
+Please note that it is generally undesirable to have all floats moved
+to the end of the manuscript. APS no longer requires this for
+submissions. In fact, the editors and referees will have an easier time
+reading the paper if the floats are set in their normal positions.
+
+\section{Rotating Floats}
+
+Often a figure or table is too wide to be typeset in the standard
+orientation and it is necessary to rotate the float 90
+degrees. \revtex~4.2 provides a new environment \env{turnpage} as an
+easy means to accomplish this. The \env{turnpage} environment depends
+on one of the packages \classname{graphics} or \classname{graphicx}
+being loaded. To use the \env{turnpage} environment, simply enclose
+the \env{figure} or \env{table} environment with the \env{turnpage}
+environment:
+\begin{verbatim}
+\documentclass[...]{revtex4-2}
+\usepackage{graphicx}
+[...]
+\begin{turnpage}
+\begin{figure} or \begin{table}
+[...]
+\end{figure} or \end{table}
+\end{turnpage}
+\end{verbatim}
+A turnpage float will be typeset on a page by itself. Currently, there
+is no mechanism for breaking such a float across multiple pages.
+
+\section{\revtex~4.2 symbols and the \classname{revsymb4-2} package}
+
+Symbols made available in earlier versions of \revtex\ are
+defined in a separate package, \classname{revsymb4-2},
+so that they may be used with other classes.
+This might be useful if, say, copying text from a \revtex\ document to
+a non-\revtex\ document. \revtex~4.2 automatically includes these
+symbols so it is not necessary to explicitly call them in with a
+\cmd\usepackage\ statement.
+
+Table~\ref{tab:revsymb} summarizes the symbols defined in this package.
+Note that \cmd{\overcirc}, \cmd{\overdots}, and \cmd{\corresponds} are
+no longer in \revtex~4.2. Use \cmd{\mathring} (standard in \LaTeXe),
+\cmd{\dddot} (with the \classoption{amsmath} package loaded), and
+\cmd\triangleq\ (with the \classoption{amssymb} class option) respectively.
+\cmd{\succsim}, \cmd{\precsim}, \cmd{\lesssim}, and \cmd{\gtrsim} are
+also defined either in \classname{amsmath} or \classname{amssymb}. The
+AMS versions of these commands will be used if the appropriate AMS
+package is loaded.
+
+\begin{table}
+\caption{\label{tab:revsymb}Special \revtex~4.2 symbols, accents, and
+boldfaced parentheses defined in \file{revsymb.sty}}
+\begin{ruledtabular}

+%To be written....
+
+\subsection{Job-specific Override Files}
+\revtex~4.2 allows manuscript-specific macro definitions to be put
+in a file separate from the main \TeX\ file. One merely creates a file
+with the same basename as the \TeX\ file, but with the extension
+`.rty'. Thus, if the \TeX\ file is names man.tex, the macro
+definitions would go in man.rty. Note that the .rty file should be in
+the same directory as the \TeX\ file. APS authors should follow the
+guidelines in the \textit{APS Author Guide for \revtex~4.2} when
+submitting. Similarly, AIP authors should refer to the \textit{Author's Guide to AIP Substyles for \revtex~4.2}

+\section{\label{sec:level1}First-level heading:\protect\\ The line
+break was forced \lowercase{via} \textbackslash\textbackslash}
+
+This sample document demonstrates proper use of REV\TeX~4.2 (and
+\LaTeXe) in manuscripts prepared for submission to AAPM
+journals. Further information can be found in the documentation included in the distribution or available at
+\url{http://www.aapm.org} and in the documentation for
+REV\TeX~4.2 itself.
+
+When commands are referred to in this example file, they are always
+shown with their required arguments, using normal \TeX{} format. In
+this format, \verb+#1+, \verb+#2+, etc. stand for required
+author-supplied arguments to commands. For example, in
+\verb+\section{#1}+ the \verb+#1+ stands for the title text of the
+author's section heading, and in \verb+\title{#1}+ the \verb+#1+
+stands for the title text of the paper.
+
+Line breaks in section headings at all levels can be introduced using
+\textbackslash\textbackslash. A blank input line tells \TeX\ that the
+paragraph has ended.
+
+\subsection{\label{sec:level2}Second-level heading: Formatting}
+
+This file may be formatted in both the \texttt{preprint} (the default) and
+\texttt{reprint} styles; the latter format may be used to
+mimic final journal output. In addition, there is another
+option available, \texttt{lengthcheck}, which formats the document as closely
+as possible to an actual journal article, to facilitate the author's
+performance of a length check. Either format may be used for submission
+purposes; however, for peer review and production, AAPM will format the
+article using the \texttt{preprint} class option. Hence, it is
+essential that authors check that their manuscripts format acceptably
+under \texttt{preprint}. Manuscripts submitted to AAPM that do not
+format correctly under the \texttt{preprint} option may be delayed in
+both the editorial and production processes.
+
+The \texttt{widetext} environment will make the text the width of the
+full page, as on page~\pageref{eq:wideeq}. (Note the use the
+\verb+\pageref{#1}+ to get the page number right automatically.) The
+width-changing commands only take effect in \texttt{twocolumn}
+formatting. It has no effect if \texttt{preprint} formatting is chosen
+instead.
+
+\subsubsection{\label{sec:level3}Third-level heading: Citations and Footnotes}
+
+Citations in text refer to entries in the Bibliography;
+they use the commands \verb+\cite{#1}+ or \verb+\onlinecite{#1}+.
+Because REV\TeX\ uses the \verb+natbib+ package of Patrick Daly,
+its entire repertoire of commands are available in your document;
+see the \verb+natbib+ documentation for further details.
+The argument of \verb+\cite+ is a comma-separated list of \emph{keys};
+a key may consist of letters and numerals.
+
+By default, AAPM citations are numerical; \cite{feyn54}
+to give a textual citation, use \verb+\onlinecite{#1}+: (Refs.~\onlinecite{witten2001,epr,Bire82}).
+REV\TeX\ ``collapses'' lists of consecutive numerical citations when appropriate.
+To illustrate, we cite several together \cite{feyn54,witten2001,epr,Berman1983},
+and once again (Refs.~\onlinecite{epr,feyn54,Bire82,Berman1983}).
+Note that, when numerical citations are used, the references were sorted into the same order they appear in the bibliography.
+
+A reference within the bibliography is specified with a \verb+\bibitem{#1}+ command,
+where the argument is the citation key mentioned above.
+\verb+\bibitem{#1}+ commands may be crafted by hand or, preferably,
+generated by using Bib\TeX.
+The AAPM styles for REV\TeX~4 include Bib\TeX\ style file
+\verb+aapmrev4-2.bst+, appropriate for
+numbered bibliography.
+REV\TeX~4 will automatically choose the style appropriate for
+the document's selected class options: the default is numerical.
+
+This sample file demonstrates a simple use of Bib\TeX\
+via a \verb+\bibliography+ command referencing the \verb+aapmsamp.bib+ file.
+Running Bib\TeX\ (in this case \texttt{bibtex
+aapmsamp}) after the first pass of \LaTeX\ produces the file
+\verb+aapmsamp.bbl+ which contains the automatically formatted
+\verb+\bibitem+ commands (including extra markup information via
+\verb+\bibinfo+ commands). If not using Bib\TeX, the
+\verb+thebibiliography+ environment should be used instead.
+
+\paragraph{Fourth-level heading is run in.}%
+Footnotes are produced using the \verb+\footnote{#1}+ command.
+Numerical style citations put footnotes into the
+bibliography\footnote{Automatically placing footnotes into the bibliography requires using BibTeX to compile the bibliography.}.
+Note: due to the method used to place footnotes in the bibliography, \emph{you
+must re-run BibTeX every time you change any of your document's
+footnotes}.
+
+\section{Math and Equations}
+Inline math may be typeset using the \verb+$+ delimiters. Bold math
+symbols may be achieved using the \verb+bm+ package and the
+\verb+\bm{#1}+ command it supplies. For instance, a bold $\alpha$ can
+be typeset as \verb+$\bm{\alpha}$+ giving $\bm{\alpha}$. Fraktur and
+Blackboard (or open face or double struck) characters should be
+typeset using the \verb+\mathfrak{#1}+ and \verb+\mathbb{#1}+ commands
+respectively. Both are supplied by the \texttt{amssymb} package. For
+example, \verb+$\mathbb{R}$+ gives $\mathbb{R}$ and
+\verb+$\mathfrak{G}$+ gives $\mathfrak{G}$
+
+In \LaTeX\ there are many different ways to display equations, and a
+few preferred ways are noted below. Displayed math will flush left by
+default.
+
+Below we have numbered single-line equations, the most common kind:
+\begin{eqnarray}
+\chi_+(p)\alt{\bf [}2|{\bf p}|(|{\bf p}|+p_z){\bf ]}^{-1/2}
+\left(
+\begin{array}{c}
+|{\bf p}|+p_z\\
+px+ip_y
+\end{array}\right)\;,
+\\
+\left\{%
+ \openone234567890abc123\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}%
+\right\}%
+\label{eq:one}.
+\end{eqnarray}
+Note the open one in Eq.~(\ref{eq:one}).
+
+Not all numbered equations will fit within a narrow column this
+way. The equation number will move down automatically if it cannot fit
+on the same line with a one-line equation:
+\begin{equation}
+\left\{
+ ab12345678abc123456abcdef\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}%
+\right\}.
+\end{equation}
+
+When the \verb+\label{#1}+ command is used [cf. input for
+Eq.~(\ref{eq:one})], the equation can be referred to in text without
+knowing the equation number that \TeX\ will assign to it. Just
+use \verb+\ref{#1}+, where \verb+#1+ is the same name that used in
+the \verb+\label{#1}+ command.
+
+Unnumbered single-line equations can be typeset
+using the \verb+\[+, \verb+\]+ format:
+\[g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~. \]
+
+\subsection{Multiline equations}
+
+Multiline equations are obtained by using the \verb+eqnarray+
+environment. Use the \verb+\nonumber+ command at the end of each line
+to avoid assigning a number:
+\begin{eqnarray}
+{\cal M}=&&ig_Z^2(4E_1E_2)^{1/2}(l_i^2)^{-1}
+\delta_{\sigma_1,-\sigma_2}
+(g_{\sigma_2}^e)^2\chi_{-\sigma_2}(p_2)\nonumber\\
+&&\times
+[\epsilon_jl_i\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1),
+\end{eqnarray}
+\begin{eqnarray}
+\sum \vert M^{\text{viol}}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
+ (N^2-1)\nonumber \\
+ & &\times \left( \sum_{i<j}\right)
+ \sum_{\text{perm}}
+ \frac{1}{S_{12}}
+ \frac{1}{S_{12}}
+ \sum_\tau c^f_\tau~.
+\end{eqnarray}
+\textbf{Note:} Do not use \verb+\label{#1}+ on a line of a multiline
+equation if \verb+\nonumber+ is also used on that line. Incorrect
+cross-referencing will result. Notice the use \verb+\text{#1}+ for
+using a Roman font within a math environment.
+
+To set a multiline equation without \emph{any} equation
+numbers, use the \verb+\begin{eqnarray*}+,
+\verb+\end{eqnarray*}+ format:
+\begin{eqnarray*}
+\sum \vert M^{\text{viol}}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
+ (N^2-1)\\
+ & &\times \left( \sum_{i<j}\right)
+ \left(
+ \sum_{\text{perm}}\frac{1}{S_{12}S_{23}S_{n1}}
+ \right)
+ \frac{1}{S_{12}}~.
+\end{eqnarray*}
+To obtain numbers not normally produced by the automatic numbering,
+use the \verb+\tag{#1}+ command, where \verb+#1+ is the desired
+equation number. For example, to get an equation number of
+(\ref{eq:mynum}),
+\begin{equation}
+g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~. \tag{2.6$'$}\label{eq:mynum}
+\end{equation}
+
+A few notes on \verb=\tag{#1}=. \verb+\tag{#1}+ requires
+\texttt{amsmath}. The \verb+\tag{#1}+ must come before the
+\verb+\label{#1}+, if any. The numbering set with \verb+\tag{#1}+ is
+\textit{transparent} to the automatic numbering in REV\TeX{};
+therefore, the number must be known ahead of time, and it must be
+manually adjusted if other equations are added. \verb+\tag{#1}+ works
+with both single-line and multiline equations. \verb+\tag{#1}+ should
+only be used in exceptional case - do not use it to number all
+equations in a paper.
+
+Note the equation number gets reset again:
+\begin{equation}
+g^+g^+g^+ \rightarrow g^+g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~.
+\end{equation}
+
+Enclosing single-line and multiline equations in
+\verb+\begin{subequations}+ and \verb+\end{subequations}+ will produce
+a set of equations that are ``numbered'' with letters, as shown in
+Eqs.~(\ref{subeq:1}) and (\ref{subeq:2}) below:
+\begin{subequations}
+\label{eq:whole}
+\begin{equation}
+\left\{
+ abc123456abcdef\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}
+\right\},\label{subeq:1}
+\end{equation}
+\begin{eqnarray}
+{\cal M}=&&ig_Z^2(4E_1E_2)^{1/2}(l_i^2)^{-1}
+(g_{\sigma_2}^e)^2\chi_{-\sigma_2}(p_2)\nonumber\\
+&&\times
+[\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1).\label{subeq:2}
+\end{eqnarray}
+\end{subequations}
+Putting a \verb+\label{#1}+ command right after the
+\verb+\begin{subequations}+, allows one to
+reference all the equations in a subequations environment. For
+example, the equations in the preceding subequations environment were
+Eqs.~(\ref{eq:whole}).
+
+\subsubsection{Wide equations}
+The equation that follows is set in a wide format, i.e., it spans
+across the full page. The wide format is reserved for long equations
+that cannot be easily broken into four lines or less:
+\begin{widetext}
+\begin{equation}
+{\cal R}^{(\text{d})}=
+ g_{\sigma_2}^e
+ \left(
+ \frac{[\Gamma^Z(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
+ +\frac{[\Gamma^Z(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
+ \right)
+ + x_WQ_e
+ \left(
+ \frac{[\Gamma^\gamma(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
+ +\frac{[\Gamma^\gamma(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
+ \right)\;. \label{eq:wideeq}
+\end{equation}
+\end{widetext}
+This is typed to show the output is in wide format.
+(Since there is no input line between \verb+\equation+ and
+this paragraph, there is no paragraph indent for this paragraph.)
+\section{Cross-referencing}
+REV\TeX{} will automatically number sections, equations, figure
+captions, and tables. In order to reference them in text, use the
+\verb+\label{#1}+ and \verb+\ref{#1}+ commands. To reference a
+particular page, use the \verb+\pageref{#1}+ command.
+
+The \verb+\label{#1}+ should appear in a section heading, within an
+equation, or in a table or figure caption. The \verb+\ref{#1}+ command
+is used in the text where the citation is to be displayed. Some
+examples: Section~\ref{sec:level1} on page~\pageref{sec:level1},
+Table~\ref{tab:table1},%
+\begin{table}
+\caption{\label{tab:table1}This is a narrow table which fits into a
+text column when using \texttt{twocolumn} formatting. Note that
+REV\TeX~4 adjusts the intercolumn spacing so that the table fills the
+entire width of the column. Table captions are numbered
+automatically. This table illustrates left-aligned, centered, and
+right-aligned columns. }
+\begin{ruledtabular}
+\begin{tabular}{lcr}
+Left\footnote{Note a.}&Centered\footnote{Note b.}&Right\\
+\hline
+1 & 2 & 3\\
+10 & 20 & 30\\
+100 & 200 & 300\\
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+and Fig.~\ref{fig:epsart}.
+
+\section{Figures and Tables}
+Figures and tables are typically ``floats''; \LaTeX\ determines their
+final position via placement rules.
+\LaTeX\ isn't always successful in automatically placing floats where you wish them.
+
+Figures are marked up with the \texttt{figure} environment, the content of which
+imports the image (\verb+\includegraphics+) followed by the figure caption (\verb+\caption+).
+The argument of the latter command should itself contain a \verb+\label+ command if you
+wish to refer to your figure with \verb+\ref+.
+
+Import your image using either the \texttt{graphics} or
+\texttt{graphix} packages. These packages both define the
+\verb+\includegraphics{#1}+ command, but they differ in the optional
+arguments for specifying the orientation, scaling, and translation of the figure.
+Fig.~\ref{fig:epsart}%
+\begin{figure}
+\includegraphics{fig_1}% Here is how to import EPS art
+\caption{\label{fig:epsart} A figure caption. The figure captions are
+automatically numbered.}
+\end{figure}
+is small enough to fit in a single column, while
+Fig.~\ref{fig:wide}%
+\begin{figure*}
+\includegraphics{fig_2}% Here is how to import EPS art
+\caption{\label{fig:wide}Use the \texttt{figure*} environment to get a wide
+figure, spanning the page in \texttt{twocolumn} formatting.}
+\end{figure*}
+is too wide for a single column,
+so instead the \texttt{figure*} environment has been used.
+
+The analog of the \texttt{figure} environment is \texttt{table}, which uses
+the same \verb+\caption+ command.
+However, you should type your caption command first within the \texttt{table},
+instead of last as you did for \texttt{figure}.
+
+The heart of any table is the \texttt{tabular} environment,
+which represents the table content as a (vertical) sequence of table rows,
+each containing a (horizontal) sequence of table cells.
+Cells are separated by the \verb+&+ character;
+the row terminates with \verb+\\+.
+The required argument for the \texttt{tabular} environment
+specifies how data are displayed in each of the columns.
+For instance, a column
+may be centered (\verb+c+), left-justified (\verb+l+), right-justified (\verb+r+),
+or aligned on a decimal point (\verb+d+).
+(Table~\ref{tab:table4}%
+\begin{table}
+\caption{\label{tab:table4}Numbers in columns Three--Five have been
+aligned by using the ``d'' column specifier (requires the
+\texttt{dcolumn} package).
+Non-numeric entries (those entries without
+a ``.'') in a ``d'' column are aligned on the decimal point.
+Use the
+``D'' specifier for more complex layouts. }
+\begin{ruledtabular}
+\begin{tabular}{ccddd}
+One&Two&\mbox{Three}&\mbox{Four}&\mbox{Five}\\
+\hline
+one&two&\mbox{three}&\mbox{four}&\mbox{five}\\
+He&2& 2.77234 & 45672. & 0.69 \\
+C\footnote{Some tables require footnotes.}
+ &C\footnote{Some tables need more than one footnote.}
+ & 12537.64 & 37.66345 & 86.37 \\
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+illustrates the use of decimal column alignment.)
+
+Extra column-spacing may be be specified as well, although
+REV\TeX~4 sets this spacing so that the columns fill the width of the
+table.
+Horizontal rules are typeset using the \verb+\hline+
+command.
+The doubled (or Scotch) rules that appear at the top and
+bottom of a table can be achieved by enclosing the \texttt{tabular}
+environment within a \texttt{ruledtabular} environment.
+Rows whose columns span multiple columns can be typeset using \LaTeX's
+\verb+\multicolumn{#1}{#2}{#3}+ command
+(for example, see the first row of Table~\ref{tab:table3}).%
+\begin{table*}
+\caption{\label{tab:table3}This is a wide table that spans the page
+width in \texttt{twocolumn} mode. It is formatted using the
+\texttt{table*} environment. It also demonstrates the use of
+\textbackslash\texttt{multicolumn} in rows with entries that span
+more than one column.}
+\begin{ruledtabular}
+\begin{tabular}{ccccc}
+ &\multicolumn{2}{c}{$D_{4h}^1$}&\multicolumn{2}{c}{$D_{4h}^5$}\\
+ Ion&1st alternative&2nd alternative&lst alternative
+&2nd alternative\\ \hline
+ K&$(2e)+(2f)$&$(4i)$ &$(2c)+(2d)$&$(4f)$ \\
+ Mn&$(2g)$\footnote{The $z$ parameter of these positions is $z\sim\frac{1}{4}$.}
+ &$(a)+(b)+(c)+(d)$&$(4e)$&$(2a)+(2b)$\\
+ Cl&$(a)+(b)+(c)+(d)$&$(2g)$\footnote{This is a footnote in a table that spans the full page
+width in \texttt{twocolumn} mode. It is supposed to set on the full width of the page, just as the caption does. }
+ &$(4e)^{\text{a}}$\\
+ He&$(8r)^{\text{a}}$&$(4j)^{\text{a}}$&$(4g)^{\text{a}}$\\
+ Ag& &$(4k)^{\text{a}}$& &$(4h)^{\text{a}}$\\
+\end{tabular}
+\end{ruledtabular}
+\end{table*}
+
+The tables in this document illustrate various effects.
+Tables that fit in a narrow column are contained in a \texttt{table}
+environment.
+Table~\ref{tab:table3} is a wide table, therefore set with the
+\texttt{table*} environment.
+Lengthy tables may need to break across pages.
+A simple way to allow this is to specify
+the \verb+[H]+ float placement on the \texttt{table} or
+\texttt{table*} environment.
+Alternatively, using the standard \LaTeXe\ package \texttt{longtable}
+gives more control over how tables break and allows headers and footers
+to be specified for each page of the table.
+An example of the use of \texttt{longtable} can be found
+in the file \texttt{summary.tex} that is included with the REV\TeX~4
+distribution.
+
+There are two methods for setting footnotes within a table (these
+footnotes will be displayed directly below the table rather than at
+the bottom of the page or in the bibliography).
+The easiest
+and preferred method is just to use the \verb+\footnote{#1}+
+command. This will automatically enumerate the footnotes with
+lowercase roman letters.
+However, it is sometimes necessary to have
+multiple entries in the table share the same footnote.
+In this case,
+create the footnotes using
+\verb+\footnotemark[#1]+ and \verb+\footnotetext[#1]{#2}+.
+\texttt{\#1} is a numeric value.
+Each time the same value for \texttt{\#1} is used,
+the same mark is produced in the table.
+The \verb+\footnotetext[#1]{#2}+ commands are placed after the \texttt{tabular}
+environment.
+Examine the \LaTeX\ source and output for Tables~\ref{tab:table1} and
+\ref{tab:table2}%
+\begin{table}
+\caption{\label{tab:table2}A table with more columns still fits
+properly in a column. Note that several entries share the same
+footnote. Inspect the \LaTeX\ input for this table to see
+exactly how it is done.}

+All AAPM journals require that the initial citation of

+\section{Appendixes}
+
+To start the appendixes, use the \verb+\appendix+ command.
+This signals that all following section commands refer to appendixes
+instead of regular sections. Therefore, the \verb+\appendix+ command
+should be used only once---to set up the section commands to act as
+appendixes. Thereafter normal section commands are used. The heading
+for a section can be left empty. For example,
+\begin{verbatim}
+\appendix
+\section{}
+\end{verbatim}
+will produce an appendix heading that says ``APPENDIX A'' and
+\begin{verbatim}
+\appendix
+\section{Background}
+\end{verbatim}
+will produce an appendix heading that says ``APPENDIX A: BACKGROUND''
+(note that the colon is set automatically).
+
+If there is only one appendix, then the letter ``A'' should not
+appear. This is suppressed by using the star version of the appendix
+command (\verb+\appendix*+ in the place of \verb+\appendix+).
+
+\section{A little more on appendixes}
+
+Observe that this appendix was started by using
+\begin{verbatim}
+\section{A little more on appendixes}
+\end{verbatim}
+
+Note the equation number in an appendix:
+\begin{equation}
+E=mc^2.
+\end{equation}
+
+\subsection{\label{app:subsec}A subsection in an appendix}
+
+You can use a subsection or subsubsection in an appendix. Note the
+numbering: we are now in Appendix~\ref{app:subsec}.
+
+\subsubsection{\label{app:subsubsec}A subsubsection in an appendix}
+Note the equation numbers in this appendix, produced with the
+subequations environment:
+\begin{subequations}
+\begin{eqnarray}
+E&=&mc, \label{appa}
+\\
+E&=&mc^2, \label{appb}
+\\
+E&\agt& mc^3. \label{appc}
+\end{eqnarray}
+\end{subequations}
+They turn out to be Eqs.~(\ref{appa}), (\ref{appb}), and (\ref{appc}).

+\section{\label{sec:level1}First-level heading:\protect\\ The line
+break was forced \lowercase{via} \textbackslash\textbackslash}
+
+This sample document demonstrates proper use of REV\TeX~4.2 (and
+\LaTeXe) in manuscripts prepared for submission to AIP
+journals. Further information can be found in the documentation included in the distribution or available at
+\url{http://authors.aip.org} and in the documentation for
+REV\TeX~4.2 itself.
+
+When commands are referred to in this example file, they are always
+shown with their required arguments, using normal \TeX{} format. In
+this format, \verb+#1+, \verb+#2+, etc. stand for required
+author-supplied arguments to commands. For example, in
+\verb+\section{#1}+ the \verb+#1+ stands for the title text of the
+author's section heading, and in \verb+\title{#1}+ the \verb+#1+
+stands for the title text of the paper.
+
+Line breaks in section headings at all levels can be introduced using
+\textbackslash\textbackslash. A blank input line tells \TeX\ that the
+paragraph has ended.
+
+\subsection{\label{sec:level2}Second-level heading: Formatting}
+
+This file may be formatted in both the \texttt{preprint} (the default) and
+\texttt{reprint} styles; the latter format may be used to
+mimic final journal output. Either format may be used for submission
+purposes; however, for peer review and production, AIP will format the
+article using the \texttt{preprint} class option. Hence, it is
+essential that authors check that their manuscripts format acceptably
+under \texttt{preprint}. Manuscripts submitted to AIP that do not
+format correctly under the \texttt{preprint} option may be delayed in
+both the editorial and production processes.
+
+The \texttt{widetext} environment will make the text the width of the
+full page, as on page~\pageref{eq:wideeq}. (Note the use the
+\verb+\pageref{#1}+ to get the page number right automatically.) The
+width-changing commands only take effect in \texttt{twocolumn}
+formatting. It has no effect if \texttt{preprint} formatting is chosen
+instead.
+
+\subsubsection{\label{sec:level3}Third-level heading: Citations and Footnotes}
+
+Citations in text refer to entries in the Bibliography;
+they use the commands \verb+\cite{#1}+ or \verb+\onlinecite{#1}+.
+Because REV\TeX\ uses the \verb+natbib+ package of Patrick Daly,
+its entire repertoire of commands are available in your document;
+see the \verb+natbib+ documentation for further details.
+The argument of \verb+\cite+ is a comma-separated list of \emph{keys};
+a key may consist of letters and numerals.
+
+By default, citations are numerical; \cite{feyn54} author-year citations are an option.
+To give a textual citation, use \verb+\onlinecite{#1}+: (Refs.~\onlinecite{witten2001,epr,Bire82}).
+REV\TeX\ ``collapses'' lists of consecutive numerical citations when appropriate.
+REV\TeX\ provides the ability to properly punctuate textual citations in author-year style;
+this facility works correctly with numerical citations only with \texttt{natbib}'s compress option turned off.
+To illustrate, we cite several together \cite{feyn54,witten2001,epr,Berman1983},
+and once again (Refs.~\onlinecite{epr,feyn54,Bire82,Berman1983}).
+Note that, when numerical citations are used, the references were sorted into the same order they appear in the bibliography.
+
+A reference within the bibliography is specified with a \verb+\bibitem{#1}+ command,
+where the argument is the citation key mentioned above.
+\verb+\bibitem{#1}+ commands may be crafted by hand or, preferably,
+generated by using Bib\TeX.
+The AIP styles for REV\TeX~4 include Bib\TeX\ style files
+\verb+aipnum.bst+ and \verb+aipauth.bst+, appropriate for
+numbered and author-year bibliographies,
+respectively.
+REV\TeX~4 will automatically choose the style appropriate for
+the document's selected class options: the default is numerical, and
+you obtain the author-year style by specifying a class option of \verb+author-year+.
+
+This sample file demonstrates a simple use of Bib\TeX\
+via a \verb+\bibliography+ command referencing the \verb+aipsamp.bib+ file.
+Running Bib\TeX\ (in this case \texttt{bibtex
+aipsamp}) after the first pass of \LaTeX\ produces the file
+\verb+aipsamp.bbl+ which contains the automatically formatted
+\verb+\bibitem+ commands (including extra markup information via
+\verb+\bibinfo+ commands). If not using Bib\TeX, the
+\verb+thebibiliography+ environment should be used instead.
+
+\paragraph{Fourth-level heading is run in.}%
+Footnotes are produced using the \verb+\footnote{#1}+ command.
+Numerical style citations put footnotes into the
+bibliography\footnote{Automatically placing footnotes into the bibliography requires using BibTeX to compile the bibliography.}.
+Author-year and numerical author-year citation styles (each for its own reason) cannot use this method.
+Note: due to the method used to place footnotes in the bibliography, \emph{you
+must re-run BibTeX every time you change any of your document's
+footnotes}.
+
+\section{Math and Equations}
+Inline math may be typeset using the \verb+$+ delimiters. Bold math
+symbols may be achieved using the \verb+bm+ package and the
+\verb+\bm{#1}+ command it supplies. For instance, a bold $\alpha$ can
+be typeset as \verb+$\bm{\alpha}$+ giving $\bm{\alpha}$. Fraktur and
+Blackboard (or open face or double struck) characters should be
+typeset using the \verb+\mathfrak{#1}+ and \verb+\mathbb{#1}+ commands
+respectively. Both are supplied by the \texttt{amssymb} package. For
+example, \verb+$\mathbb{R}$+ gives $\mathbb{R}$ and
+\verb+$\mathfrak{G}$+ gives $\mathfrak{G}$
+
+In \LaTeX\ there are many different ways to display equations, and a
+few preferred ways are noted below. Displayed math will center by
+default. Use the class option \verb+fleqn+ to flush equations left.
+
+Below we have numbered single-line equations, the most common kind:
+\begin{eqnarray}
+\chi_+(p)\alt{\bf [}2|{\bf p}|(|{\bf p}|+p_z){\bf ]}^{-1/2}
+\left(
+\begin{array}{c}
+|{\bf p}|+p_z\\
+px+ip_y
+\end{array}\right)\;,
+\\
+\left\{%
+ \openone234567890abc123\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}%
+\right\}%
+\label{eq:one}.
+\end{eqnarray}
+Note the open one in Eq.~(\ref{eq:one}).
+
+Not all numbered equations will fit within a narrow column this
+way. The equation number will move down automatically if it cannot fit
+on the same line with a one-line equation:
+\begin{equation}
+\left\{
+ ab12345678abc123456abcdef\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}%
+\right\}.
+\end{equation}
+
+When the \verb+\label{#1}+ command is used [cf. input for
+Eq.~(\ref{eq:one})], the equation can be referred to in text without
+knowing the equation number that \TeX\ will assign to it. Just
+use \verb+\ref{#1}+, where \verb+#1+ is the same name that used in
+the \verb+\label{#1}+ command.
+
+Unnumbered single-line equations can be typeset
+using the \verb+\[+, \verb+\]+ format:
+\[g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~. \]
+
+\subsection{Multiline equations}
+
+Multiline equations are obtained by using the \verb+eqnarray+
+environment. Use the \verb+\nonumber+ command at the end of each line
+to avoid assigning a number:
+\begin{eqnarray}
+{\cal M}=&&ig_Z^2(4E_1E_2)^{1/2}(l_i^2)^{-1}
+\delta_{\sigma_1,-\sigma_2}
+(g_{\sigma_2}^e)^2\chi_{-\sigma_2}(p_2)\nonumber\\
+&&\times
+[\epsilon_jl_i\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1),
+\end{eqnarray}
+\begin{eqnarray}
+\sum \vert M^{\text{viol}}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
+ (N^2-1)\nonumber \\
+ & &\times \left( \sum_{i<j}\right)
+ \sum_{\text{perm}}
+ \frac{1}{S_{12}}
+ \frac{1}{S_{12}}
+ \sum_\tau c^f_\tau~.
+\end{eqnarray}
+\textbf{Note:} Do not use \verb+\label{#1}+ on a line of a multiline
+equation if \verb+\nonumber+ is also used on that line. Incorrect
+cross-referencing will result. Notice the use \verb+\text{#1}+ for
+using a Roman font within a math environment.
+
+To set a multiline equation without \emph{any} equation
+numbers, use the \verb+\begin{eqnarray*}+,
+\verb+\end{eqnarray*}+ format:
+\begin{eqnarray*}
+\sum \vert M^{\text{viol}}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
+ (N^2-1)\\
+ & &\times \left( \sum_{i<j}\right)
+ \left(
+ \sum_{\text{perm}}\frac{1}{S_{12}S_{23}S_{n1}}
+ \right)
+ \frac{1}{S_{12}}~.
+\end{eqnarray*}
+To obtain numbers not normally produced by the automatic numbering,
+use the \verb+\tag{#1}+ command, where \verb+#1+ is the desired
+equation number. For example, to get an equation number of
+(\ref{eq:mynum}),
+\begin{equation}
+g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~. \tag{2.6$'$}\label{eq:mynum}
+\end{equation}
+
+A few notes on \verb=\tag{#1}=. \verb+\tag{#1}+ requires
+\texttt{amsmath}. The \verb+\tag{#1}+ must come before the
+\verb+\label{#1}+, if any. The numbering set with \verb+\tag{#1}+ is
+\textit{transparent} to the automatic numbering in REV\TeX{};
+therefore, the number must be known ahead of time, and it must be
+manually adjusted if other equations are added. \verb+\tag{#1}+ works
+with both single-line and multiline equations. \verb+\tag{#1}+ should
+only be used in exceptional case - do not use it to number all
+equations in a paper.
+
+Enclosing single-line and multiline equations in
+\verb+\begin{subequations}+ and \verb+\end{subequations}+ will produce
+a set of equations that are ``numbered'' with letters, as shown in
+Eqs.~(\ref{subeq:1}) and (\ref{subeq:2}) below:
+\begin{subequations}
+\label{eq:whole}

+Putting a \verb+\label{#1}+ command right after the
+\verb+\begin{subequations}+, allows one to
+reference all the equations in a subequations environment. For
+example, the equations in the preceding subequations environment were
+Eqs.~(\ref{eq:whole}).
+
+\subsubsection{Wide equations}
+The equation that follows is set in a wide format, i.e., it spans
+across the full page. The wide format is reserved for long equations
+that cannot be easily broken into four lines or less:
+\begin{widetext}
+\begin{equation}
+{\cal R}^{(\text{d})}=
+ g_{\sigma_2}^e
+ \left(
+ \frac{[\Gamma^Z(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
+ +\frac{[\Gamma^Z(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
+ \right)
+ + x_WQ_e
+ \left(
+ \frac{[\Gamma^\gamma(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
+ +\frac{[\Gamma^\gamma(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
+ \right)\;. \label{eq:wideeq}
+\end{equation}
+\end{widetext}
+This is typed to show the output is in wide format.
+(Since there is no input line between \verb+\equation+ and
+this paragraph, there is no paragraph indent for this paragraph.)
+\section{Cross-referencing}
+REV\TeX{} will automatically number sections, equations, figure
+captions, and tables. In order to reference them in text, use the
+\verb+\label{#1}+ and \verb+\ref{#1}+ commands. To reference a
+particular page, use the \verb+\pageref{#1}+ command.
+
+The \verb+\label{#1}+ should appear in a section heading, within an
+equation, or in a table or figure caption. The \verb+\ref{#1}+ command
+is used in the text where the citation is to be displayed. Some
+examples: Section~\ref{sec:level1} on page~\pageref{sec:level1},
+Table~\ref{tab:table1},%
+\begin{table}
+\caption{\label{tab:table1}This is a narrow table which fits into a
+text column when using \texttt{twocolumn} formatting. Note that
+REV\TeX~4 adjusts the intercolumn spacing so that the table fills the
+entire width of the column. Table captions are numbered
+automatically. This table illustrates left-aligned, centered, and
+right-aligned columns. }
+\begin{ruledtabular}
+\begin{tabular}{lcr}
+Left\footnote{Note a.}&Centered\footnote{Note b.}&Right\\
+\hline
+1 & 2 & 3\\
+10 & 20 & 30\\
+100 & 200 & 300\\
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+and Fig.~\ref{fig:epsart}.
+
+\section{Figures and Tables}
+Figures and tables are typically ``floats''; \LaTeX\ determines their
+final position via placement rules.
+\LaTeX\ isn't always successful in automatically placing floats where you wish them.
+
+Figures are marked up with the \texttt{figure} environment, the content of which
+imports the image (\verb+\includegraphics+) followed by the figure caption (\verb+\caption+).
+The argument of the latter command should itself contain a \verb+\label+ command if you
+wish to refer to your figure with \verb+\ref+.
+
+Import your image using either the \texttt{graphics} or
+\texttt{graphix} packages. These packages both define the
+\verb+\includegraphics{#1}+ command, but they differ in the optional
+arguments for specifying the orientation, scaling, and translation of the figure.
+Fig.~\ref{fig:epsart}%
+\begin{figure}
+\includegraphics{fig_1}% Here is how to import EPS art
+\caption{\label{fig:epsart} A figure caption. The figure captions are
+automatically numbered.}
+\end{figure}
+is small enough to fit in a single column, while
+Fig.~\ref{fig:wide}%
+\begin{figure*}
+\includegraphics{fig_2}% Here is how to import EPS art
+\caption{\label{fig:wide}Use the \texttt{figure*} environment to get a wide
+figure, spanning the page in \texttt{twocolumn} formatting.}
+\end{figure*}
+is too wide for a single column,
+so instead the \texttt{figure*} environment has been used.
+
+The analog of the \texttt{figure} environment is \texttt{table}, which uses
+the same \verb+\caption+ command.
+However, you should type your caption command first within the \texttt{table},
+instead of last as you did for \texttt{figure}.
+
+The heart of any table is the \texttt{tabular} environment,
+which represents the table content as a (vertical) sequence of table rows,
+each containing a (horizontal) sequence of table cells.
+Cells are separated by the \verb+&+ character;
+the row terminates with \verb+\\+.
+The required argument for the \texttt{tabular} environment
+specifies how data are displayed in each of the columns.
+For instance, a column
+may be centered (\verb+c+), left-justified (\verb+l+), right-justified (\verb+r+),
+or aligned on a decimal point (\verb+d+).
+(Table~\ref{tab:table4}%
+\begin{table}
+\caption{\label{tab:table4}Numbers in columns Three--Five have been
+aligned by using the ``d'' column specifier (requires the
+\texttt{dcolumn} package).
+Non-numeric entries (those entries without
+a ``.'') in a ``d'' column are aligned on the decimal point.
+Use the
+``D'' specifier for more complex layouts. }
+\begin{ruledtabular}
+\begin{tabular}{ccddd}
+One&Two&\mbox{Three}&\mbox{Four}&\mbox{Five}\\
+\hline
+one&two&\mbox{three}&\mbox{four}&\mbox{five}\\
+He&2& 2.77234 & 45672. & 0.69 \\
+C\footnote{Some tables require footnotes.}
+ &C\footnote{Some tables need more than one footnote.}
+ & 12537.64 & 37.66345 & 86.37 \\
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+illustrates the use of decimal column alignment.)
+
+Extra column-spacing may be be specified as well, although
+REV\TeX~4 sets this spacing so that the columns fill the width of the
+table.
+Horizontal rules are typeset using the \verb+\hline+
+command.
+The doubled (or Scotch) rules that appear at the top and
+bottom of a table can be achieved by enclosing the \texttt{tabular}
+environment within a \texttt{ruledtabular} environment.
+Rows whose columns span multiple columns can be typeset using \LaTeX's
+\verb+\multicolumn{#1}{#2}{#3}+ command
+(for example, see the first row of Table~\ref{tab:table3}).%
+\begin{table*}
+\caption{\label{tab:table3}This is a wide table that spans the page
+width in \texttt{twocolumn} mode. It is formatted using the
+\texttt{table*} environment. It also demonstrates the use of
+\textbackslash\texttt{multicolumn} in rows with entries that span
+more than one column.}
+\begin{ruledtabular}
+\begin{tabular}{ccccc}
+ &\multicolumn{2}{c}{$D_{4h}^1$}&\multicolumn{2}{c}{$D_{4h}^5$}\\
+ Ion&1st alternative&2nd alternative&lst alternative
+&2nd alternative\\ \hline
+ K&$(2e)+(2f)$&$(4i)$ &$(2c)+(2d)$&$(4f)$ \\
+ Mn&$(2g)$\footnote{The $z$ parameter of these positions is $z\sim\frac{1}{4}$.}
+ &$(a)+(b)+(c)+(d)$&$(4e)$&$(2a)+(2b)$\\
+ Cl&$(a)+(b)+(c)+(d)$&$(2g)$\footnote{This is a footnote in a table that spans the full page
+width in \texttt{twocolumn} mode. It is supposed to set on the full width of the page, just as the caption does. }
+ &$(4e)^{\text{a}}$\\
+ He&$(8r)^{\text{a}}$&$(4j)^{\text{a}}$&$(4g)^{\text{a}}$\\
+ Ag& &$(4k)^{\text{a}}$& &$(4h)^{\text{a}}$\\
+\end{tabular}
+\end{ruledtabular}
+\end{table*}
+
+The tables in this document illustrate various effects.
+Tables that fit in a narrow column are contained in a \texttt{table}
+environment.
+Table~\ref{tab:table3} is a wide table, therefore set with the
+\texttt{table*} environment.
+Lengthy tables may need to break across pages.
+A simple way to allow this is to specify
+the \verb+[H]+ float placement on the \texttt{table} or
+\texttt{table*} environment.
+Alternatively, using the standard \LaTeXe\ package \texttt{longtable}
+gives more control over how tables break and allows headers and footers
+to be specified for each page of the table.
+An example of the use of \texttt{longtable} can be found
+in the file \texttt{summary.tex} that is included with the REV\TeX~4
+distribution.
+
+There are two methods for setting footnotes within a table (these
+footnotes will be displayed directly below the table rather than at
+the bottom of the page or in the bibliography).
+The easiest
+and preferred method is just to use the \verb+\footnote{#1}+
+command. This will automatically enumerate the footnotes with
+lowercase roman letters.
+However, it is sometimes necessary to have
+multiple entries in the table share the same footnote.
+In this case,
+create the footnotes using
+\verb+\footnotemark[#1]+ and \verb+\footnotetext[#1]{#2}+.
+\texttt{\#1} is a numeric value.
+Each time the same value for \texttt{\#1} is used,
+the same mark is produced in the table.
+The \verb+\footnotetext[#1]{#2}+ commands are placed after the \texttt{tabular}
+environment.
+Examine the \LaTeX\ source and output for Tables~\ref{tab:table1} and
+\ref{tab:table2}%
+\begin{table}
+\caption{\label{tab:table2}A table with more columns still fits
+properly in a column. Note that several entries share the same
+footnote. Inspect the \LaTeX\ input for this table to see
+exactly how it is done.}

+All AIP journals require that the initial citation of

+\LaTeX's automatic numbering of floats is your friend here:
+just put each \texttt{figure} environment immediately following
+its first reference (\verb+\ref+), as we have done in this example file.

+\section{Appendixes}
+
+To start the appendixes, use the \verb+\appendix+ command.
+This signals that all following section commands refer to appendixes
+instead of regular sections. Therefore, the \verb+\appendix+ command
+should be used only once---to set up the section commands to act as
+appendixes. Thereafter normal section commands are used. The heading
+for a section can be left empty. For example,
+\begin{verbatim}
+\appendix
+\section{}
+\end{verbatim}
+will produce an appendix heading that says ``APPENDIX A'' and
+\begin{verbatim}
+\appendix
+\section{Background}
+\end{verbatim}
+will produce an appendix heading that says ``APPENDIX A: BACKGROUND''
+(note that the colon is set automatically).
+
+If there is only one appendix, then the letter ``A'' should not
+appear. This is suppressed by using the star version of the appendix
+command (\verb+\appendix*+ in the place of \verb+\appendix+).
+
+\section{A little more on appendixes}
+
+Observe that this appendix was started by using
+\begin{verbatim}
+\section{A little more on appendixes}
+\end{verbatim}
+
+Note the equation number in an appendix:
+\begin{equation}
+E=mc^2.
+\end{equation}
+
+\subsection{\label{app:subsec}A subsection in an appendix}
+
+You can use a subsection or subsubsection in an appendix. Note the
+numbering: we are now in Appendix~\ref{app:subsec}.
+
+\subsubsection{\label{app:subsubsec}A subsubsection in an appendix}
+Note the equation numbers in this appendix, produced with the
+subequations environment:
+\begin{subequations}
+\begin{eqnarray}
+E&=&mc, \label{appa}
+\\
+E&=&mc^2, \label{appb}
+\\
+E&\agt& mc^3. \label{appc}
+\end{eqnarray}
+\end{subequations}
+They turn out to be Eqs.~(\ref{appa}), (\ref{appb}), and (\ref{appc}).

+\begin{description}
+\item[Usage]
+Secondary publications and information retrieval purposes.
+\item[Structure]
+You may use the \texttt{description} environment to structure your abstract;
+use the optional argument of the \verb+\item+ command to give the category of each item.

+\section{\label{sec:level1}First-level heading:\protect\\ The line
+break was forced \lowercase{via} \textbackslash\textbackslash}
+
+This sample document demonstrates proper use of REV\TeX~4.2 (and
+\LaTeXe) in mansucripts prepared for submission to APS
+journals. Further information can be found in the REV\TeX~4.2
+documentation included in the distribution or available at
+\url{http://journals.aps.org/revtex/}.
+
+When commands are referred to in this example file, they are always
+shown with their required arguments, using normal \TeX{} format. In
+this format, \verb+#1+, \verb+#2+, etc. stand for required
+author-supplied arguments to commands. For example, in
+\verb+\section{#1}+ the \verb+#1+ stands for the title text of the
+author's section heading, and in \verb+\title{#1}+ the \verb+#1+
+stands for the title text of the paper.
+
+Line breaks in section headings at all levels can be introduced using
+\textbackslash\textbackslash. A blank input line tells \TeX\ that the
+paragraph has ended. Note that top-level section headings are
+automatically uppercased. If a specific letter or word should appear in
+lowercase instead, you must escape it using \verb+\lowercase{#1}+ as
+in the word ``via'' above.
+
+\subsection{\label{sec:level2}Second-level heading: Formatting}
+
+This file may be formatted in either the \texttt{preprint} or
+\texttt{reprint} style. \texttt{reprint} format mimics final journal output.
+Either format may be used for submission purposes. \texttt{letter} sized paper should
+be used when submitting to APS journals.
+
+\subsubsection{Wide text (A level-3 head)}
+The \texttt{widetext} environment will make the text the width of the
+full page, as on page~\pageref{eq:wideeq}. (Note the use the
+\verb+\pageref{#1}+ command to refer to the page number.)
+\paragraph{Note (Fourth-level head is run in)}
+The width-changing commands only take effect in two-column formatting.
+There is no effect if text is in a single column.
+
+\subsection{\label{sec:citeref}Citations and References}
+A citation in text uses the command \verb+\cite{#1}+ or
+\verb+\onlinecite{#1}+ and refers to an entry in the bibliography.
+An entry in the bibliography is a reference to another document.
+
+\subsubsection{Citations}
+Because REV\TeX\ uses the \verb+natbib+ package of Patrick Daly,
+the entire repertoire of commands in that package are available for your document;
+see the \verb+natbib+ documentation for further details. Please note that
+REV\TeX\ requires version 8.31a or later of \verb+natbib+.
+
+\paragraph{Syntax}
+The argument of \verb+\cite+ may be a single \emph{key},
+or may consist of a comma-separated list of keys.
+The citation \emph{key} may contain
+letters, numbers, the dash (-) character, or the period (.) character.
+New with natbib 8.3 is an extension to the syntax that allows for
+a star (*) form and two optional arguments on the citation key itself.
+The syntax of the \verb+\cite+ command is thus (informally stated)
+\begin{quotation}\flushleft\leftskip1em
+\verb+\cite+ \verb+{+ \emph{key} \verb+}+, or\\
+\verb+\cite+ \verb+{+ \emph{optarg+key} \verb+}+, or\\
+\verb+\cite+ \verb+{+ \emph{optarg+key} \verb+,+ \emph{optarg+key}\ldots \verb+}+,
+\end{quotation}\noindent
+where \emph{optarg+key} signifies
+\begin{quotation}\flushleft\leftskip1em
+\emph{key}, or\\
+\texttt{*}\emph{key}, or\\
+\texttt{[}\emph{pre}\texttt{]}\emph{key}, or\\
+\texttt{[}\emph{pre}\texttt{]}\texttt{[}\emph{post}\texttt{]}\emph{key}, or even\\
+\texttt{*}\texttt{[}\emph{pre}\texttt{]}\texttt{[}\emph{post}\texttt{]}\emph{key}.
+\end{quotation}\noindent
+where \emph{pre} and \emph{post} is whatever text you wish to place
+at the beginning and end, respectively, of the bibliographic reference
+(see Ref.~[\onlinecite{witten2001}] and the two under Ref.~[\onlinecite{feyn54}]).
+(Keep in mind that no automatic space or punctuation is applied.)
+It is highly recommended that you put the entire \emph{pre} or \emph{post} portion
+within its own set of braces, for example:
+\verb+\cite+ \verb+{+ \texttt{[} \verb+{+\emph{text}\verb+}+\texttt{]}\emph{key}\verb+}+.
+The extra set of braces will keep \LaTeX\ out of trouble if your \emph{text} contains the comma (,) character.
+
+The star (*) modifier to the \emph{key} signifies that the reference is to be
+merged with the previous reference into a single bibliographic entry,
+a common idiom in APS and AIP articles (see below, Ref.~[\onlinecite{epr}]).
+When references are merged in this way, they are separated by a semicolon instead of
+the period (full stop) that would otherwise appear.
+
+\paragraph{Eliding repeated information}
+When a reference is merged, some of its fields may be elided: for example,
+when the author matches that of the previous reference, it is omitted.
+If both author and journal match, both are omitted.
+If the journal matches, but the author does not, the journal is replaced by \emph{ibid.},
+as exemplified by Ref.~[\onlinecite{epr}].
+These rules embody common editorial practice in APS and AIP journals and will only
+be in effect if the markup features of the APS and AIP Bib\TeX\ styles is employed.
+
+\paragraph{The options of the cite command itself}
+Please note that optional arguments to the \emph{key} change the reference in the bibliography,
+not the citation in the body of the document.
+For the latter, use the optional arguments of the \verb+\cite+ command itself:
+\verb+\cite+ \texttt{*}\allowbreak
+\texttt{[}\emph{pre-cite}\texttt{]}\allowbreak
+\texttt{[}\emph{post-cite}\texttt{]}\allowbreak
+\verb+{+\emph{key-list}\verb+}+.
+
+\subsubsection{Example citations}
+By default, citations are numerical\cite{Beutler1994}.
+Author-year citations are used when the journal is RMP.
+To give a textual citation, use \verb+\onlinecite{#1}+:
+Refs.~\onlinecite{[][{, and references therein}]witten2001,Bire82}.
+By default, the \texttt{natbib} package automatically sorts your citations into numerical order and ``compresses'' runs of three or more consecutive numerical citations.
+REV\TeX\ provides the ability to automatically change the punctuation when switching between journal styles that provide citations in square brackets and those that use a superscript style instead. This is done through the \texttt{citeautoscript} option. For instance, the journal style \texttt{prb} automatically invokes this option because \textit{Physical
+Review B} uses superscript-style citations. The effect is to move the punctuation, which normally comes after a citation in square brackets, to its proper position before the superscript.
+To illustrate, we cite several together
+\cite{[See the explanation of time travel in ]feyn54,*[The classical relativistic treatment of ][ is a relative classic]epr,witten2001,Berman1983,Davies1998,Bire82},
+and once again in different order (Refs.~\cite{epr,feyn54,Bire82,Berman1983,witten2001,Davies1998}).
+Note that the citations were both compressed and sorted. Futhermore, running this sample file under the \texttt{prb} option will move the punctuation to the correct place.
+
+When the \verb+prb+ class option is used, the \verb+\cite{#1}+ command
+displays the reference's number as a superscript rather than in
+square brackets. Note that the location of the \verb+\cite{#1}+
+command should be adjusted for the reference style: the superscript
+references in \verb+prb+ style must appear after punctuation;
+otherwise the reference must appear before any punctuation. This
+sample was written for the regular (non-\texttt{prb}) citation style.
+The command \verb+\onlinecite{#1}+ in the \texttt{prb} style also
+displays the reference on the baseline.
+
+\subsubsection{References}
+A reference in the bibliography is specified by a \verb+\bibitem{#1}+ command
+with the same argument as the \verb+\cite{#1}+ command.
+\verb+\bibitem{#1}+ commands may be crafted by hand or, preferably,
+generated by Bib\TeX.
+REV\TeX~4.2 includes Bib\TeX\ style files
+\verb+apsrev4-2.bst+, \verb+apsrmp4-2.bst+ appropriate for
+\textit{Physical Review} and \textit{Reviews of Modern Physics},
+respectively.
+
+\subsubsection{Example references}
+This sample file employs the \verb+\bibliography+ command,
+which formats the \texttt{\jobname .bbl} file
+and specifies which bibliographic databases are to be used by Bib\TeX\
+(one of these should be by arXiv convention \texttt{\jobname .bib}).
+Running Bib\TeX\ (via \texttt{bibtex \jobname})
+after the first pass of \LaTeX\ produces the file
+\texttt{\jobname .bbl} which contains the automatically formatted
+\verb+\bibitem+ commands (including extra markup information via
+\verb+\bibinfo+ and \verb+\bibfield+ commands).
+If not using Bib\TeX, you will have to create the \verb+thebibiliography+ environment
+and its \verb+\bibitem+ commands by hand.
+
+Numerous examples of the use of the APS bibliographic entry types appear in the bibliography of this sample document.
+You can refer to the \texttt{\jobname .bib} file,
+and compare its information to the formatted bibliography itself.
+
+\subsection{Footnotes}%
+Footnotes, produced using the \verb+\footnote{#1}+ command,
+usually integrated into the bibliography alongside the other entries.
+Numerical citation styles do this%
+\footnote{Automatically placing footnotes into the bibliography requires using BibTeX to compile the bibliography.};
+author-year citation styles place the footnote at the bottom of the text column.
+Note: due to the method used to place footnotes in the bibliography,
+\emph{you must re-run Bib\TeX\ every time you change any of your document's footnotes}.
+
+\section{Math and Equations}
+Inline math may be typeset using the \verb+$+ delimiters. Bold math
+symbols may be achieved using the \verb+bm+ package and the
+\verb+\bm{#1}+ command it supplies. For instance, a bold $\alpha$ can
+be typeset as \verb+$\bm{\alpha}$+ giving $\bm{\alpha}$. Fraktur and
+Blackboard (or open face or double struck) characters should be
+typeset using the \verb+\mathfrak{#1}+ and \verb+\mathbb{#1}+ commands
+respectively. Both are supplied by the \texttt{amssymb} package. For
+example, \verb+$\mathbb{R}$+ gives $\mathbb{R}$ and
+\verb+$\mathfrak{G}$+ gives $\mathfrak{G}$
+
+In \LaTeX\ there are many different ways to display equations, and a
+few preferred ways are noted below. Displayed math will center by
+default. Use the class option \verb+fleqn+ to flush equations left.
+
+Below we have numbered single-line equations; this is the most common
+type of equation in \textit{Physical Review}:
+\begin{eqnarray}
+\chi_+(p)\alt{\bf [}2|{\bf p}|(|{\bf p}|+p_z){\bf ]}^{-1/2}
+\left(
+\begin{array}{c}
+|{\bf p}|+p_z\\
+px+ip_y
+\end{array}\right)\;,
+\\
+\left\{%
+ \openone234567890abc123\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}%
+\right\}%
+\label{eq:one}.
+\end{eqnarray}
+Note the open one in Eq.~(\ref{eq:one}).
+
+Not all numbered equations will fit within a narrow column this
+way. The equation number will move down automatically if it cannot fit
+on the same line with a one-line equation:
+\begin{equation}
+\left\{
+ ab12345678abc123456abcdef\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}%
+\right\}.
+\end{equation}
+
+When the \verb+\label{#1}+ command is used [cf. input for
+Eq.~(\ref{eq:one})], the equation can be referred to in text without
+knowing the equation number that \TeX\ will assign to it. Just
+use \verb+\ref{#1}+, where \verb+#1+ is the same name that used in
+the \verb+\label{#1}+ command.
+
+Unnumbered single-line equations can be typeset
+using the \verb+\[+, \verb+\]+ format:
+\[g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~. \]
+
+
+\subsection{Multiline equations}
+
+Multiline equations are obtained by using the \verb+eqnarray+
+environment. Use the \verb+\nonumber+ command at the end of each line
+to avoid assigning a number:
+\begin{eqnarray}
+{\cal M}=&&ig_Z^2(4E_1E_2)^{1/2}(l_i^2)^{-1}
+\delta_{\sigma_1,-\sigma_2}
+(g_{\sigma_2}^e)^2\chi_{-\sigma_2}(p_2)\nonumber\\
+&&\times
+[\epsilon_jl_i\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1),
+\end{eqnarray}
+\begin{eqnarray}
+\sum \vert M^{\text{viol}}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
+ (N^2-1)\nonumber \\
+ & &\times \left( \sum_{i<j}\right)
+ \sum_{\text{perm}}
+ \frac{1}{S_{12}}
+ \frac{1}{S_{12}}
+ \sum_\tau c^f_\tau~.
+\end{eqnarray}
+\textbf{Note:} Do not use \verb+\label{#1}+ on a line of a multiline
+equation if \verb+\nonumber+ is also used on that line. Incorrect
+cross-referencing will result. Notice the use \verb+\text{#1}+ for
+using a Roman font within a math environment.
+
+To set a multiline equation without \emph{any} equation
+numbers, use the \verb+\begin{eqnarray*}+,
+\verb+\end{eqnarray*}+ format:
+\begin{eqnarray*}
+\sum \vert M^{\text{viol}}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
+ (N^2-1)\\
+ & &\times \left( \sum_{i<j}\right)
+ \left(
+ \sum_{\text{perm}}\frac{1}{S_{12}S_{23}S_{n1}}
+ \right)
+ \frac{1}{S_{12}}~.
+\end{eqnarray*}
+
+To obtain numbers not normally produced by the automatic numbering,
+use the \verb+\tag{#1}+ command, where \verb+#1+ is the desired
+equation number. For example, to get an equation number of
+(\ref{eq:mynum}),
+\begin{equation}
+g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~. \tag{2.6$'$}\label{eq:mynum}
+\end{equation}
+
+\paragraph{A few notes on \texttt{tag}s}
+\verb+\tag{#1}+ requires the \texttt{amsmath} package.
+Place the \verb+\tag{#1}+ command before the \verb+\label{#1}+, if any.
+The numbering produced by \verb+\tag{#1}+ \textit{does not affect}
+the automatic numbering in REV\TeX;
+therefore, the number must be known ahead of time,
+and it must be manually adjusted if other equations are added.
+\verb+\tag{#1}+ works with both single-line and multiline equations.
+\verb+\tag{#1}+ should only be used in exceptional cases---%
+do not use it to number many equations in your paper.
+Please note that this feature of the \texttt{amsmath} package
+is \emph{not} compatible with the \texttt{hyperref} (6.77u) package.
+
+Enclosing display math within
+\verb+\begin{subequations}+ and \verb+\end{subequations}+ will produce
+a set of equations that are labeled with letters, as shown in
+Eqs.~(\ref{subeq:1}) and (\ref{subeq:2}) below.
+You may include any number of single-line and multiline equations,
+although it is probably not a good idea to follow one display math
+directly after another.
+\begin{subequations}
+\label{eq:whole}
+\begin{eqnarray}
+{\cal M}=&&ig_Z^2(4E_1E_2)^{1/2}(l_i^2)^{-1}
+(g_{\sigma_2}^e)^2\chi_{-\sigma_2}(p_2)\nonumber\\
+&&\times
+[\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1).\label{subeq:2}
+\end{eqnarray}
+\begin{equation}
+\left\{
+ abc123456abcdef\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}
+\right\},\label{subeq:1}
+\end{equation}
+\end{subequations}
+Giving a \verb+\label{#1}+ command directly after the \verb+\begin{subequations}+,
+allows you to reference all the equations in the \texttt{subequations} environment.
+For example, the equations in the preceding subequations environment were
+Eqs.~(\ref{eq:whole}).
+
+\subsubsection{Wide equations}
+The equation that follows is set in a wide format, i.e., it spans the full page.
+The wide format is reserved for long equations
+that cannot easily be set in a single column:
+\begin{widetext}
+\begin{equation}
+{\cal R}^{(\text{d})}=
+ g_{\sigma_2}^e
+ \left(
+ \frac{[\Gamma^Z(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
+ +\frac{[\Gamma^Z(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
+ \right)
+ + x_WQ_e
+ \left(
+ \frac{[\Gamma^\gamma(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
+ +\frac{[\Gamma^\gamma(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
+ \right)\;.
+ \label{eq:wideeq}
+\end{equation}
+\end{widetext}
+This is typed to show how the output appears in wide format.
+(Incidentally, since there is no blank line between the \texttt{equation} environment above
+and the start of this paragraph, this paragraph is not indented.)
+
+\section{Cross-referencing}
+REV\TeX{} will automatically number such things as
+sections, footnotes, equations, figure captions, and table captions.
+In order to reference them in text, use the
+\verb+\label{#1}+ and \verb+\ref{#1}+ commands.
+To reference a particular page, use the \verb+\pageref{#1}+ command.
+
+The \verb+\label{#1}+ should appear
+within the section heading,
+within the footnote text,
+within the equation, or
+within the table or figure caption.
+The \verb+\ref{#1}+ command
+is used in text at the point where the reference is to be displayed.
+Some examples: Section~\ref{sec:level1} on page~\pageref{sec:level1},
+Table~\ref{tab:table1},%
+\begin{table}[b]%The best place to locate the table environment is directly after its first reference in text
+\caption{\label{tab:table1}%
+A table that fits into a single column of a two-column layout.
+Note that REV\TeX~4 adjusts the intercolumn spacing so that the table fills the
+entire width of the column. Table captions are numbered
+automatically.
+This table illustrates left-, center-, decimal- and right-aligned columns,
+along with the use of the \texttt{ruledtabular} environment which sets the
+Scotch (double) rules above and below the alignment, per APS style.

+\end{figure}
+
+\section{Floats: Figures, Tables, Videos, etc.}
+Figures and tables are usually allowed to ``float'', which means that their
+placement is determined by \LaTeX, while the document is being typeset.
+
+Use the \texttt{figure} environment for a figure, the \texttt{table} environment for a table.
+In each case, use the \verb+\caption+ command within to give the text of the
+figure or table caption along with the \verb+\label+ command to provide
+a key for referring to this figure or table.
+The typical content of a figure is an image of some kind;
+that of a table is an alignment.%
+\begin{figure*}
+\includegraphics{fig_2}% Here is how to import EPS art
+\caption{\label{fig:wide}Use the figure* environment to get a wide
+figure that spans the page in \texttt{twocolumn} formatting.}
+\end{figure*}
+\begin{table*}
+\caption{\label{tab:table3}This is a wide table that spans the full page
+width in a two-column layout. It is formatted using the
+\texttt{table*} environment. It also demonstates the use of
+\textbackslash\texttt{multicolumn} in rows with entries that span
+more than one column.}
+\begin{ruledtabular}
+\begin{tabular}{ccccc}
+ &\multicolumn{2}{c}{$D_{4h}^1$}&\multicolumn{2}{c}{$D_{4h}^5$}\\

+\end{tabular}
+\end{ruledtabular}
+\end{table*}
+
+Insert an image using either the \texttt{graphics} or
+\texttt{graphix} packages, which define the \verb+\includegraphics{#1}+ command.
+(The two packages differ in respect of the optional arguments
+used to specify the orientation, scaling, and translation of the image.)
+To create an alignment, use the \texttt{tabular} environment.
+
+The best place to locate the \texttt{figure} or \texttt{table} environment
+is immediately following its first reference in text; this sample document
+illustrates this practice for Fig.~\ref{fig:epsart}, which
+shows a figure that is small enough to fit in a single column.
+
+In exceptional cases, you will need to move the float earlier in the document, as was done
+with Table~\ref{tab:table3}: \LaTeX's float placement algorithms need to know
+about a full-page-width float earlier.
+
+Fig.~\ref{fig:wide}
+has content that is too wide for a single column,
+so the \texttt{figure*} environment has been used.%
+\begin{table}[b]
+\caption{\label{tab:table4}%
+Numbers in columns Three--Five are aligned with the ``d'' column specifier
+(requires the \texttt{dcolumn} package).
+Non-numeric entries (those entries without a ``.'') in a ``d'' column are aligned on the decimal point.
+Use the ``D'' specifier for more complex layouts. }
+\begin{ruledtabular}
+\begin{tabular}{ccddd}
+One&Two&
+\multicolumn{1}{c}{\textrm{Three}}&
+\multicolumn{1}{c}{\textrm{Four}}&
+\multicolumn{1}{c}{\textrm{Five}}\\

+\end{tabular}
+\end{ruledtabular}
+\end{table}
+
+The content of a table is typically a \texttt{tabular} environment,
+giving rows of type in aligned columns.
+Column entries separated by \verb+&+'s, and
+each row ends with \textbackslash\textbackslash.
+The required argument for the \texttt{tabular} environment
+specifies how data are aligned in the columns.
+For instance, entries may be centered, left-justified, right-justified, aligned on a decimal
+point.
+Extra column-spacing may be be specified as well,
+although REV\TeX~4 sets this spacing so that the columns fill the width of the
+table. Horizontal rules are typeset using the \verb+\hline+
+command. The doubled (or Scotch) rules that appear at the top and
+bottom of a table can be achieved enclosing the \texttt{tabular}
+environment within a \texttt{ruledtabular} environment. Rows whose
+columns span multiple columns can be typeset using the
+\verb+\multicolumn{#1}{#2}{#3}+ command (for example, see the first
+row of Table~\ref{tab:table3}).%

+show various effects.
+A table that fits in a single column employs the \texttt{table}
+environment.
+Table~\ref{tab:table3} is a wide table, set with the \texttt{table*} environment.
+Long tables may need to break across pages.
+The most straightforward way to accomplish this is to specify
+the \verb+[H]+ float placement on the \texttt{table} or
+\texttt{table*} environment.
+However, the \LaTeXe\ package \texttt{longtable} allows headers and footers to be specified for each page of the table.
+A simple example of the use of \texttt{longtable} can be found
+in the file \texttt{summary.tex} that is included with the REV\TeX~4
+distribution.
+
+There are two methods for setting footnotes within a table (these
+footnotes will be displayed directly below the table rather than at
+the bottom of the page or in the bibliography). The easiest
+and preferred method is just to use the \verb+\footnote{#1}+
+command. This will automatically enumerate the footnotes with
+lowercase roman letters. However, it is sometimes necessary to have
+multiple entries in the table share the same footnote. In this case,
+there is no choice but to manually create the footnotes using
+\verb+\footnotemark[#1]+ and \verb+\footnotetext[#1]{#2}+.
+\texttt{\#1} is a numeric value. Each time the same value for
+\texttt{\#1} is used, the same mark is produced in the table. The
+\verb+\footnotetext[#1]{#2}+ commands are placed after the \texttt{tabular}
+environment. Examine the \LaTeX\ source and output for
+Tables~\ref{tab:table1} and \ref{tab:table2}
+for examples.
+
+Video~\ref{vid:PRSTPER.4.010101}
+illustrates several features new with REV\TeX4.2,
+starting with the \texttt{video} environment, which is in the same category with
+\texttt{figure} and \texttt{table}.%
+\begin{video}
+\href{http://prst-per.aps.org/multimedia/PRSTPER/v4/i1/e010101/e010101_vid1a.mpg}{\includegraphics{vid_1a}}%
+ \quad
+\href{http://prst-per.aps.org/multimedia/PRSTPER/v4/i1/e010101/e010101_vid1b.mpg}{\includegraphics{vid_1b}}
+ \setfloatlink{http://link.aps.org/multimedia/PRSTPER/v4/i1/e010101}%
+ \caption{\label{vid:PRSTPER.4.010101}%
+ Students explain their initial idea about Newton's third law to a teaching assistant.
+ Clip (a): same force.
+ Clip (b): move backwards.
+ }%
+\end{video}
+The \verb+\setfloatlink+ command causes the title of the video to be a hyperlink to the
+indicated URL; it may be used with any environment that takes the \verb+\caption+
+command.
+The \verb+\href+ command has the same significance as it does in the context of
+the \texttt{hyperref} package: the second argument is a piece of text to be
+typeset in your document; the first is its hyperlink, a URL.
+
+\textit{Physical Review} style requires that the initial citation of
+figures or tables be in numerical order in text, so don't cite
+Fig.~\ref{fig:wide} until Fig.~\ref{fig:epsart} has been cited.

+
+\section{Appendixes}
+
+To start the appendixes, use the \verb+\appendix+ command.
+This signals that all following section commands refer to appendixes
+instead of regular sections. Therefore, the \verb+\appendix+ command
+should be used only once---to setup the section commands to act as
+appendixes. Thereafter normal section commands are used. The heading
+for a section can be left empty. For example,
+\begin{verbatim}
+\appendix
+\section{}
+\end{verbatim}
+will produce an appendix heading that says ``APPENDIX A'' and
+\begin{verbatim}
+\appendix
+\section{Background}
+\end{verbatim}
+will produce an appendix heading that says ``APPENDIX A: BACKGROUND''
+(note that the colon is set automatically).
+
+If there is only one appendix, then the letter ``A'' should not
+appear. This is suppressed by using the star version of the appendix
+command (\verb+\appendix*+ in the place of \verb+\appendix+).
+
+\section{A little more on appendixes}
+
+Observe that this appendix was started by using
+\begin{verbatim}
+\section{A little more on appendixes}
+\end{verbatim}
+
+Note the equation number in an appendix:
+\begin{equation}
+E=mc^2.
+\end{equation}
+
+\subsection{\label{app:subsec}A subsection in an appendix}
+
+You can use a subsection or subsubsection in an appendix. Note the
+numbering: we are now in Appendix~\ref{app:subsec}.
+
+Note the equation numbers in this appendix, produced with the
+subequations environment:
+\begin{subequations}
+\begin{eqnarray}
+E&=&mc, \label{appa}
+\\
+E&=&mc^2, \label{appb}
+\\
+E&\agt& mc^3. \label{appc}
+\end{eqnarray}
+\end{subequations}
+They turn out to be Eqs.~(\ref{appa}), (\ref{appb}), and (\ref{appc}).

+
+\begin{quotation}
+The ``lead paragraph'' is encapsulated with the \LaTeX\
+\verb+quotation+ environment and is formatted as a single paragraph before the first section heading.
+(The \verb+quotation+ environment reverts to its usual meaning after the first sectioning command.)
+Note that numbered references are allowed in the lead paragraph.
+%
+The lead paragraph will only be found in an article being prepared for the journal \textit{Chaos}.

+
+\section{\label{sec:level1}First-level heading:\protect\\ The line
+break was forced \lowercase{via} \textbackslash\textbackslash}
+
+This sample document demonstrates proper use of REV\TeX~4.2 (and
+\LaTeXe) in manuscripts prepared for submission to AIP
+journals. Further information can be found in the documentation included in the distribution or available at
+\url{http://authors.aip.org} and in the documentation for
+REV\TeX~4.2 itself.
+
+When commands are referred to in this example file, they are always
+shown with their required arguments, using normal \TeX{} format. In
+this format, \verb+#1+, \verb+#2+, etc. stand for required
+author-supplied arguments to commands. For example, in
+\verb+\section{#1}+ the \verb+#1+ stands for the title text of the
+author's section heading, and in \verb+\title{#1}+ the \verb+#1+
+stands for the title text of the paper.
+
+Line breaks in section headings at all levels can be introduced using
+\textbackslash\textbackslash. A blank input line tells \TeX\ that the
+paragraph has ended.
+
+\subsection{\label{sec:level2}Second-level heading: Formatting}
+
+This file may be formatted in both the \texttt{preprint} (the default) and
+\texttt{reprint} styles; the latter format may be used to
+mimic final journal output. Either format may be used for submission
+purposes; however, for peer review and production, AIP will format the
+article using the \texttt{preprint} class option. Hence, it is
+essential that authors check that their manuscripts format acceptably
+under \texttt{preprint}. Manuscripts submitted to AIP that do not
+format correctly under the \texttt{preprint} option may be delayed in
+both the editorial and production processes.
+
+The \texttt{widetext} environment will make the text the width of the
+full page, as on page~\pageref{eq:wideeq}. (Note the use the
+\verb+\pageref{#1}+ to get the page number right automatically.) The
+width-changing commands only take effect in \texttt{twocolumn}
+formatting. It has no effect if \texttt{preprint} formatting is chosen
+instead.
+
+\subsubsection{\label{sec:level3}Third-level heading: Citations and Footnotes}
+
+Citations in text refer to entries in the Bibliography;
+they use the commands \verb+\cite{#1}+ or \verb+\onlinecite{#1}+.
+Because REV\TeX\ uses the \verb+natbib+ package of Patrick Daly,
+its entire repertoire of commands are available in your document;
+see the \verb+natbib+ documentation for further details.
+The argument of \verb+\cite+ is a comma-separated list of \emph{keys};
+a key may consist of letters and numerals.
+
+By default, citations are numerical; \cite{feyn54} author-year citations are an option.
+To give a textual citation, use \verb+\onlinecite{#1}+: (Refs.~\onlinecite{witten2001,epr,Bire82}).
+REV\TeX\ ``collapses'' lists of consecutive numerical citations when appropriate.
+REV\TeX\ provides the ability to properly punctuate textual citations in author-year style;
+this facility works correctly with numerical citations only with \texttt{natbib}'s compress option turned off.
+To illustrate, we cite several together \cite{feyn54,witten2001,epr,Berman1983},
+and once again (Refs.~\onlinecite{epr,feyn54,Bire82,Berman1983}).
+Note that, when numerical citations are used, the references were sorted into the same order they appear in the bibliography.
+
+A reference within the bibliography is specified with a \verb+\bibitem{#1}+ command,
+where the argument is the citation key mentioned above.
+\verb+\bibitem{#1}+ commands may be crafted by hand or, preferably,
+generated by using Bib\TeX.
+The AIP styles for REV\TeX~4 include Bib\TeX\ style files
+\verb+aipnum.bst+ and \verb+aipauth.bst+, appropriate for
+numbered and author-year bibliographies,
+respectively.
+REV\TeX~4 will automatically choose the style appropriate for
+the document's selected class options: the default is numerical, and
+you obtain the author-year style by specifying a class option of \verb+author-year+.
+
+This sample file demonstrates a simple use of Bib\TeX\
+via a \verb+\bibliography+ command referencing the \verb+sorsamp.bib+ file.
+Running Bib\TeX\ (in this case \texttt{bibtex
+sorsamp}) after the first pass of \LaTeX\ produces the file
+\verb+sorsamp.bbl+ which contains the automatically formatted
+\verb+\bibitem+ commands (including extra markup information via
+\verb+\bibinfo+ commands). If not using Bib\TeX, the
+\verb+thebibiliography+ environment should be used instead.
+
+\paragraph{Fourth-level heading is run in.}%
+Footnotes are produced using the \verb+\footnote{#1}+ command.
+Numerical style citations put footnotes into the
+bibliography\footnote{Automatically placing footnotes into the bibliography requires using BibTeX to compile the bibliography.}.
+Author-year and numerical author-year citation styles (each for its own reason) cannot use this method.
+Note: due to the method used to place footnotes in the bibliography, \emph{you
+must re-run BibTeX every time you change any of your document's
+footnotes}.
+
+\section{Math and Equations}
+Inline math may be typeset using the \verb+$+ delimiters. Bold math
+symbols may be achieved using the \verb+bm+ package and the
+\verb+\bm{#1}+ command it supplies. For instance, a bold $\alpha$ can
+be typeset as \verb+$\bm{\alpha}$+ giving $\bm{\alpha}$. Fraktur and
+Blackboard (or open face or double struck) characters should be
+typeset using the \verb+\mathfrak{#1}+ and \verb+\mathbb{#1}+ commands
+respectively. Both are supplied by the \texttt{amssymb} package. For
+example, \verb+$\mathbb{R}$+ gives $\mathbb{R}$ and
+\verb+$\mathfrak{G}$+ gives $\mathfrak{G}$
+
+In \LaTeX\ there are many different ways to display equations, and a
+few preferred ways are noted below. Displayed math will center by
+default. Use the class option \verb+fleqn+ to flush equations left.
+
+Below we have numbered single-line equations, the most common kind:
+\begin{eqnarray}
+\chi_+(p)\alt{\bf [}2|{\bf p}|(|{\bf p}|+p_z){\bf ]}^{-1/2}
+\left(
+\begin{array}{c}
+|{\bf p}|+p_z\\
+px+ip_y
+\end{array}\right)\;,
+\\
+\left\{%
+ \openone234567890abc123\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}%
+\right\}%
+\label{eq:one}.
+\end{eqnarray}
+Note the open one in Eq.~(\ref{eq:one}).
+
+Not all numbered equations will fit within a narrow column this
+way. The equation number will move down automatically if it cannot fit
+on the same line with a one-line equation:
+\begin{equation}
+\left\{
+ ab12345678abc123456abcdef\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}%
+\right\}.
+\end{equation}
+
+When the \verb+\label{#1}+ command is used [cf. input for
+Eq.~(\ref{eq:one})], the equation can be referred to in text without
+knowing the equation number that \TeX\ will assign to it. Just
+use \verb+\ref{#1}+, where \verb+#1+ is the same name that used in
+the \verb+\label{#1}+ command.
+
+Unnumbered single-line equations can be typeset
+using the \verb+\[+, \verb+\]+ format:
+\[g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~. \]
+
+\subsection{Multiline equations}
+
+Multiline equations are obtained by using the \verb+eqnarray+
+environment. Use the \verb+\nonumber+ command at the end of each line
+to avoid assigning a number:
+\begin{eqnarray}
+{\cal M}=&&ig_Z^2(4E_1E_2)^{1/2}(l_i^2)^{-1}
+\delta_{\sigma_1,-\sigma_2}
+(g_{\sigma_2}^e)^2\chi_{-\sigma_2}(p_2)\nonumber\\
+&&\times
+[\epsilon_jl_i\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1),
+\end{eqnarray}
+\begin{eqnarray}
+\sum \vert M^{\text{viol}}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
+ (N^2-1)\nonumber \\
+ & &\times \left( \sum_{i<j}\right)
+ \sum_{\text{perm}}
+ \frac{1}{S_{12}}
+ \frac{1}{S_{12}}
+ \sum_\tau c^f_\tau~.
+\end{eqnarray}
+\textbf{Note:} Do not use \verb+\label{#1}+ on a line of a multiline
+equation if \verb+\nonumber+ is also used on that line. Incorrect
+cross-referencing will result. Notice the use \verb+\text{#1}+ for
+using a Roman font within a math environment.
+
+To set a multiline equation without \emph{any} equation
+numbers, use the \verb+\begin{eqnarray*}+,
+\verb+\end{eqnarray*}+ format:
+\begin{eqnarray*}
+\sum \vert M^{\text{viol}}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
+ (N^2-1)\\
+ & &\times \left( \sum_{i<j}\right)
+ \left(
+ \sum_{\text{perm}}\frac{1}{S_{12}S_{23}S_{n1}}
+ \right)
+ \frac{1}{S_{12}}~.
+\end{eqnarray*}
+To obtain numbers not normally produced by the automatic numbering,
+use the \verb+\tag{#1}+ command, where \verb+#1+ is the desired
+equation number. For example, to get an equation number of
+(\ref{eq:mynum}),
+\begin{equation}
+g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
+q^+g^+g^+ \dots ~. \tag{2.6$'$}\label{eq:mynum}
+\end{equation}
+
+A few notes on \verb=\tag{#1}=. \verb+\tag{#1}+ requires
+\texttt{amsmath}. The \verb+\tag{#1}+ must come before the
+\verb+\label{#1}+, if any. The numbering set with \verb+\tag{#1}+ is
+\textit{transparent} to the automatic numbering in REV\TeX{};
+therefore, the number must be known ahead of time, and it must be
+manually adjusted if other equations are added. \verb+\tag{#1}+ works
+with both single-line and multiline equations. \verb+\tag{#1}+ should
+only be used in exceptional case - do not use it to number all
+equations in a paper.
+
+Enclosing single-line and multiline equations in
+\verb+\begin{subequations}+ and \verb+\end{subequations}+ will produce
+a set of equations that are ``numbered'' with letters, as shown in
+Eqs.~(\ref{subeq:1}) and (\ref{subeq:2}) below:
+\begin{subequations}
+\label{eq:whole}
+\begin{equation}
+\left\{
+ abc123456abcdef\alpha\beta\gamma\delta1234556\alpha\beta
+ \frac{1\sum^{a}_{b}}{A^2}
+\right\},\label{subeq:1}
+\end{equation}
+\begin{eqnarray}
+{\cal M}=&&ig_Z^2(4E_1E_2)^{1/2}(l_i^2)^{-1}
+(g_{\sigma_2}^e)^2\chi_{-\sigma_2}(p_2)\nonumber\\
+&&\times
+[\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1).\label{subeq:2}
+\end{eqnarray}
+\end{subequations}
+Putting a \verb+\label{#1}+ command right after the
+\verb+\begin{subequations}+, allows one to
+reference all the equations in a subequations environment. For
+example, the equations in the preceding subequations environment were
+Eqs.~(\ref{eq:whole}).
+
+\subsubsection{Wide equations}
+The equation that follows is set in a wide format, i.e., it spans
+across the full page. The wide format is reserved for long equations
+that cannot be easily broken into four lines or less:
+\begin{widetext}
+\begin{equation}
+{\cal R}^{(\text{d})}=
+ g_{\sigma_2}^e
+ \left(
+ \frac{[\Gamma^Z(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
+ +\frac{[\Gamma^Z(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
+ \right)
+ + x_WQ_e
+ \left(
+ \frac{[\Gamma^\gamma(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
+ +\frac{[\Gamma^\gamma(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
+ \right)\;. \label{eq:wideeq}
+\end{equation}
+\end{widetext}
+This is typed to show the output is in wide format.
+(Since there is no input line between \verb+\equation+ and
+this paragraph, there is no paragraph indent for this paragraph.)
+\section{Cross-referencing}
+REV\TeX{} will automatically number sections, equations, figure
+captions, and tables. In order to reference them in text, use the
+\verb+\label{#1}+ and \verb+\ref{#1}+ commands. To reference a
+particular page, use the \verb+\pageref{#1}+ command.
+
+The \verb+\label{#1}+ should appear in a section heading, within an
+equation, or in a table or figure caption. The \verb+\ref{#1}+ command
+is used in the text where the citation is to be displayed. Some
+examples: Section~\ref{sec:level1} on page~\pageref{sec:level1},
+Table~\ref{tab:table1},%
+\begin{table}
+\caption{\label{tab:table1}This is a narrow table which fits into a
+text column when using \texttt{twocolumn} formatting. Note that
+REV\TeX~4 adjusts the intercolumn spacing so that the table fills the
+entire width of the column. Table captions are numbered
+automatically. This table illustrates left-aligned, centered, and
+right-aligned columns. }
+\begin{ruledtabular}
+\begin{tabular}{lcr}
+Left\footnote{Note a.}&Centered\footnote{Note b.}&Right\\
+\hline
+1 & 2 & 3\\
+10 & 20 & 30\\
+100 & 200 & 300\\
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+and Fig.~\ref{fig:epsart}.
+
+\section{Figures and Tables}
+Figures and tables are typically ``floats''; \LaTeX\ determines their
+final position via placement rules.
+\LaTeX\ isn't always successful in automatically placing floats where you wish them.
+
+Figures are marked up with the \texttt{figure} environment, the content of which
+imports the image (\verb+\includegraphics+) followed by the figure caption (\verb+\caption+).
+The argument of the latter command should itself contain a \verb+\label+ command if you
+wish to refer to your figure with \verb+\ref+.
+
+Import your image using either the \texttt{graphics} or
+\texttt{graphix} packages. These packages both define the
+\verb+\includegraphics{#1}+ command, but they differ in the optional
+arguments for specifying the orientation, scaling, and translation of the figure.
+Fig.~\ref{fig:epsart}%
+\begin{figure}
+\includegraphics{fig_1}% Here is how to import EPS art
+\caption{\label{fig:epsart} A figure caption. The figure captions are
+automatically numbered.}
+\end{figure}
+is small enough to fit in a single column, while
+Fig.~\ref{fig:wide}%
+\begin{figure*}
+\includegraphics{fig_2}% Here is how to import EPS art
+\caption{\label{fig:wide}Use the \texttt{figure*} environment to get a wide
+figure, spanning the page in \texttt{twocolumn} formatting.}
+\end{figure*}
+is too wide for a single column,
+so instead the \texttt{figure*} environment has been used.
+
+The analog of the \texttt{figure} environment is \texttt{table}, which uses
+the same \verb+\caption+ command.
+However, you should type your caption command first within the \texttt{table},
+instead of last as you did for \texttt{figure}.
+
+The heart of any table is the \texttt{tabular} environment,
+which represents the table content as a (vertical) sequence of table rows,
+each containing a (horizontal) sequence of table cells.
+Cells are separated by the \verb+&+ character;
+the row terminates with \verb+\\+.
+The required argument for the \texttt{tabular} environment
+specifies how data are displayed in each of the columns.
+For instance, a column
+may be centered (\verb+c+), left-justified (\verb+l+), right-justified (\verb+r+),
+or aligned on a decimal point (\verb+d+).
+(Table~\ref{tab:table4}%
+\begin{table}
+\caption{\label{tab:table4}Numbers in columns Three--Five have been
+aligned by using the ``d'' column specifier (requires the
+\texttt{dcolumn} package).
+Non-numeric entries (those entries without
+a ``.'') in a ``d'' column are aligned on the decimal point.
+Use the
+``D'' specifier for more complex layouts. }
+\begin{ruledtabular}
+\begin{tabular}{ccddd}
+One&Two&\mbox{Three}&\mbox{Four}&\mbox{Five}\\
+\hline
+one&two&\mbox{three}&\mbox{four}&\mbox{five}\\
+He&2& 2.77234 & 45672. & 0.69 \\
+C\footnote{Some tables require footnotes.}
+ &C\footnote{Some tables need more than one footnote.}
+ & 12537.64 & 37.66345 & 86.37 \\
+\end{tabular}
+\end{ruledtabular}
+\end{table}
+illustrates the use of decimal column alignment.)
+
+Extra column-spacing may be be specified as well, although
+REV\TeX~4 sets this spacing so that the columns fill the width of the
+table.
+Horizontal rules are typeset using the \verb+\hline+
+command.
+The doubled (or Scotch) rules that appear at the top and
+bottom of a table can be achieved by enclosing the \texttt{tabular}
+environment within a \texttt{ruledtabular} environment.
+Rows whose columns span multiple columns can be typeset using \LaTeX's
+\verb+\multicolumn{#1}{#2}{#3}+ command
+(for example, see the first row of Table~\ref{tab:table3}).%
+\begin{table*}
+\caption{\label{tab:table3}This is a wide table that spans the page
+width in \texttt{twocolumn} mode. It is formatted using the
+\texttt{table*} environment. It also demonstrates the use of
+\textbackslash\texttt{multicolumn} in rows with entries that span
+more than one column.}
+\begin{ruledtabular}
+\begin{tabular}{ccccc}
+ &\multicolumn{2}{c}{$D_{4h}^1$}&\multicolumn{2}{c}{$D_{4h}^5$}\\
+ Ion&1st alternative&2nd alternative&lst alternative
+&2nd alternative\\ \hline
+ K&$(2e)+(2f)$&$(4i)$ &$(2c)+(2d)$&$(4f)$ \\
+ Mn&$(2g)$\footnote{The $z$ parameter of these positions is $z\sim\frac{1}{4}$.}
+ &$(a)+(b)+(c)+(d)$&$(4e)$&$(2a)+(2b)$\\
+ Cl&$(a)+(b)+(c)+(d)$&$(2g)$\footnote{This is a footnote in a table that spans the full page
+width in \texttt{twocolumn} mode. It is supposed to set on the full width of the page, just as the caption does. }
+ &$(4e)^{\text{a}}$\\
+ He&$(8r)^{\text{a}}$&$(4j)^{\text{a}}$&$(4g)^{\text{a}}$\\
+ Ag& &$(4k)^{\text{a}}$& &$(4h)^{\text{a}}$\\
+\end{tabular}
+\end{ruledtabular}
+\end{table*}
+
+The tables in this document illustrate various effects.
+Tables that fit in a narrow column are contained in a \texttt{table}
+environment.
+Table~\ref{tab:table3} is a wide table, therefore set with the
+\texttt{table*} environment.
+Lengthy tables may need to break across pages.
+A simple way to allow this is to specify
+the \verb+[H]+ float placement on the \texttt{table} or
+\texttt{table*} environment.
+Alternatively, using the standard \LaTeXe\ package \texttt{longtable}
+gives more control over how tables break and allows headers and footers
+to be specified for each page of the table.
+An example of the use of \texttt{longtable} can be found
+in the file \texttt{summary.tex} that is included with the REV\TeX~4
+distribution.
+
+There are two methods for setting footnotes within a table (these
+footnotes will be displayed directly below the table rather than at
+the bottom of the page or in the bibliography).
+The easiest
+and preferred method is just to use the \verb+\footnote{#1}+
+command. This will automatically enumerate the footnotes with
+lowercase roman letters.
+However, it is sometimes necessary to have
+multiple entries in the table share the same footnote.
+In this case,
+create the footnotes using
+\verb+\footnotemark[#1]+ and \verb+\footnotetext[#1]{#2}+.
+\texttt{\#1} is a numeric value.
+Each time the same value for \texttt{\#1} is used,
+the same mark is produced in the table.
+The \verb+\footnotetext[#1]{#2}+ commands are placed after the \texttt{tabular}
+environment.
+Examine the \LaTeX\ source and output for Tables~\ref{tab:table1} and
+\ref{tab:table2}%
+\begin{table}
+\caption{\label{tab:table2}A table with more columns still fits
+properly in a column. Note that several entries share the same
+footnote. Inspect the \LaTeX\ input for this table to see
+exactly how it is done.}

+All AIP journals require that the initial citation of

+\LaTeX's automatic numbering of floats is your friend here:

+its first reference (\verb+\ref+), as we have done in this example file.

+\section{Appendixes}
+
+To start the appendixes, use the \verb+\appendix+ command.
+This signals that all following section commands refer to appendixes
+instead of regular sections. Therefore, the \verb+\appendix+ command
+should be used only once---to set up the section commands to act as
+appendixes. Thereafter normal section commands are used. The heading
+for a section can be left empty. For example,
+\begin{verbatim}
+\appendix
+\section{}
+\end{verbatim}
+will produce an appendix heading that says ``APPENDIX A'' and
+\begin{verbatim}
+\appendix
+\section{Background}
+\end{verbatim}
+will produce an appendix heading that says ``APPENDIX A: BACKGROUND''
+(note that the colon is set automatically).
+
+If there is only one appendix, then the letter ``A'' should not
+appear. This is suppressed by using the star version of the appendix
+command (\verb+\appendix*+ in the place of \verb+\appendix+).
+
+\section{A little more on appendixes}
+
+Observe that this appendix was started by using
+\begin{verbatim}
+\section{A little more on appendixes}
+\end{verbatim}
+
+Note the equation number in an appendix:
+\begin{equation}
+E=mc^2.
+\end{equation}
+
+\subsection{\label{app:subsec}A subsection in an appendix}
+
+You can use a subsection or subsubsection in an appendix. Note the
+numbering: we are now in Appendix~\ref{app:subsec}.
+
+\subsubsection{\label{app:subsubsec}A subsubsection in an appendix}
+Note the equation numbers in this appendix, produced with the
+subequations environment:
+\begin{subequations}
+\begin{eqnarray}
+E&=&mc, \label{appa}
+\\
+E&=&mc^2, \label{appb}
+\\
+E&\agt& mc^3. \label{appc}
+\end{eqnarray}
+\end{subequations}
+They turn out to be Eqs.~(\ref{appa}), (\ref{appb}), and (\ref{appc}).

+%
+% \subsubsection{Generated by \texttt{latex aip.dtx}}%

+%
+% \subsubsection{Auxiliary}%
+% The following are auxiliary files generated
+% in the course of running \LaTeX:

+%
+% \section{Code common to all modules}%
+%
+% The following may look a bit klootchy, but we
+% want to require only one place in this file
+% where the version number is stated,
+% and we also want to ensure that the version
+% number is embedded into every generated file.
+%
+% Now we declare that
+% these files can only be used with \LaTeXe.
+% An appropriate message is displayed if
+% a different \TeX{} format is used.
+% \begin{macrocode}
+%<*driver|package>
+\NeedsTeXFormat{LaTeX2e}[1996/12/01]%
+%</driver|package>
+% \end{macrocode}
+% As desired, the following modules all

+%<package>\ProvidesFile{aip4-1.rtx}%
+%<*driver>
+\expandafter\ProvidesFile\expandafter{\jobname.dtx}%
+%</driver>
+% \end{macrocode}
+%
+% The following line contains, for once and for all,

+%
+%
+% \section{The driver module \texttt{driver}}
+%
+% This module, consisting of the present section,
+% typesets the programmer's documentation,
+% generating the \file{.ins} installer and \file{README} as required.
+%
+% Because the only uncommented-out lines of code at the beginning of
+% this file constitute the \file{driver} module itself,
+% we can simply typeset the \file{.dtx} file directly,
+% and there is thus rarely any need to
+% generate the ``driver'' {\sc docstrip} module.
+% Module delimiters are nonetheless required so that
+% this code does not find its way into the other modules.
+%
+% The \enve{document} command concludes the typesetting run.
+%
+% \begin{macrocode}
+%<*driver>
+% \end{macrocode}
+%
+% \subsection{The Preamble}
+% The programmers documentation is formatted
+% with the \classname{ltxdoc} class with local customizations,
+% and with the usual code line indexing.
+% \begin{macrocode}
+\documentclass{ltxdoc}
+\RequirePackage{ltxdocext}%
+\let\url\undefined

+%
+% \subsubsection{Docstrip and info directives}
+% We use so many {\sc docstrip} modules that we set the
+% \texttt{StandardModuleDepth} counter to 1.
+% \begin{macrocode}
+\setcounter{StandardModuleDepth}{1}
+% \end{macrocode}
+% The following command retrieves the date and version information
+% from this file.

+%
+% \subsection{The ``Read Me'' File}
+% As promised above, here is the contents of the
+% ``Read Me'' file. That file serves a double purpose,
+% since it also constitutes the beginining of the
+% programmer's documentation. What better thing, after
+% all, to have appear at the beginning of the
+% typeset documentation?
+%
+% A good discussion of how to write a ReadMe file can be found in
+% Engst, Tonya, ``Writing a ReadMe File? Read This''
+% \emph{MacTech} October 1998, p. 58.
+%
+% Note the appearance of the
+% \cmd\StopEventually\ command, which marks the
+% dividing line between the user documentation
+% and the programmer documentation.
+%
+% The usual user will not be asked to
+% do a full build, not to speak
+% of the bootstrap.
+% Instructions for carrying these processes
+% begin the programmer's manual.

+This file embodies the implementation of the
+AIP journal substyles for APS's \revtex\ 4.1 document class
+for electronic submissions to AIP journals.
+
+The distribution point for this work is
+\url{http://authors.aip.org/REVTEX}.
+The archive contains ready-to-Install files, documentation, and full source.
+
+This package is also distributed via CTAN:
+\url{http://www.ctan.org/pub/tex-archive/macros/latex/contrib/aip}, and as a ready-to-install image as
+\url{http://www.ctan.org/pub/tex-archive/install/macros/latex/contrib/aip.tds.zip}.
+
+The \classname{aip} package was commissioned by the American Institute of Physics
+and is distributed under the terms of the \LaTeX\ Project Public License,
+the same license under which all the portions of \LaTeX\ itself is distributed.
+Please see \url{http://ctan.tug.org/macros/latex/base/lppl.txt} for details.
+
+To use this document class, you must have a working
+\TeX\ installation equipped with \LaTeXe\
+and possibly pdftex and Adobe Acrobat Reader or equivalent.
+
+To install, retrieve the distribution,
+unpack it into a directory on the target computer,
+and move the file \file{aip.rtx}
+into a location in your filesystem where it will be found by \LaTeX.
+
+To use, read the user documentation \file{auguide.pdf}.
+
+\tableofcontents
+
+\section{Overview}%
+\revtex\ is a \LaTeXe\ document class, somewhat like a hybrid of
+the standard \LaTeX\ \classname{book} and \classname{article} classes.
+
+This document class implements the AIP society and journal substyles:
+the journals represent a set of mutually exclusive class options that, in this case, allow the
+document class to address multiple journals within the AIP family.
+This society is obtained with class option \classoption{aip}.
+
+\section{Processing Instructions}
+
+The package file \file{aip.rtx}
+is generated from this file, \file{aip.dtx},
+using the {\sc docstrip} facility of \LaTeX
+via |tex aip.dtx|.
+The typeset documentation that you are now reading is generated from
+the same file by typesetting it with \LaTeX\ or pdftex
+via |latex aip.dtx| or |pdflatex aip.dtx|.
+
+\subsection{Build Instructions}
+
+You may bootstrap this suite of files solely from \file{aip.dtx}.
+Prepare by installing \LaTeXe\ (and either tex or pdftex) on your computer,
+then carry out the following steps:
+\begin{enumerate}
+\item
+Within an otherwise empty directory,
+typeset \file{aip.dtx} with \LaTeX\ or pdflatex;
+you will obtain the typeset documentation you are now reading,
+along with
+the installer \file{aip.ins},
+and the file \file{README}.
+
+Note: you will have to run \LaTeX\ twice, then \file{makeindex}, then
+\LaTeX\ again in order to obtain a valid index and table of contents.
+\item
+Now typeset \file{aip.dtx} with \TeX (not \LaTeX),
+thereby generating the package file \file{aip.rtx}.
+\item
+Install \classname{aip.rtx}
+by moving it to a location
+in your filesystem where it will be found by \LaTeX,
+like \file{tex/latex/aip}.
+\item
+Install \classname{aip.pdf}
+by moving it to
+\file{doc/latex/aip}.
+\item
+Using the \file{.dbj} information herein,
+generate the needed \file{.bst} files and install them in
+\file{bibtex/bst/aip}.
+\end{enumerate}
+\end{filecontents*}

+%
+% \subsection{The Document Body}
+%
+% Here is the document body, containing only a
+% \cmd\DocInput\ directive---referring to this very file.
+% This very cute self-reference is a common \classname{ltxdoc} idiom.

+%
+% \section{AIP: A set of journal-specifc extensions to \revtex}
+%
+% To create a journal substyle, you create
+% a \file{.rtx} file, in our case \file{aip.rtx}.
+% Within that file, you override procedures and parameter assignments as you see fit.
+% Ideally they will be generally applicable to all of that society's
+% journals (see the file \file{aps.rtx} for a realization of this scheme).
+% Also within that file, you include a
+% section of code for each journal, that for JMP looks like:
+% \begin{verbatim}
+% \@ifx{\@journal\journal@jmp}{%
+% <code specific to the JMP>
+% }{}%
+% \end{verbatim}
+%
+% \section{The \classoption{aip} class option: the \texttt{aip} module}
+% The file \file{aip.rtx} is read in by the \classname{revtex4} document class
+% if \cmd\@society\ has the value \classoption{aip}.
+%
+% Here, code specific to AIP journals appears.
+%
+% We first give some text entities (amounting to journal abbreviations),
+% then some AIP-specific initialisations,
+% then code for particular AIP journals.
+% In the latter case, the choice is
+% keyed off the macro \cmd\@journal.
+%
+% Note on \cmd\AtEndOfClass:
+% this file, like all journal substyles, is read in at \cmd\AtEndOfClass\ time,
+% so you should not use this command in this file.
+% Note for \LaTeX\ developers: It would be an improvement in \LaTeX\ to
+% \cmd\let\cmd\AtEndOfClass\ to something like \cmd\@firstofone.
+% This change would be effected in \cmd\@onefilewithoptions.
+%
+% \begin{macrocode}

+% \end{macrocode}
+%
+% Optionally allow article title in bibliography entries.
+% A new switch is defined here: \cmd\aip@jtitx@sw\ signifies that
+% the numbered style bibliography is to be prepared without article titles in @ARTICLE entries.
+% Otherwise, such titles are incorporated if present in the \file{.bib} entry.
+% By default, exclude the article titles.

+% Between the two files \file{aipnum.dbj} and \file{aipauth.dbj},
+% the differences are limited:
+% \file{aipnum.dbj} has two lines lacking in \file{aipauth.dbj}:
+% \begin{verbatim}
+% seq-no,%: Citation order (unsorted, like unsrt.bst)
+% nm-init,ed-au,%: Initials + surname (J. F. Smith)
+% \end{verbatim}
+% thus, the ``numbered citation'' bibliography is sorted by citation order, and
+% the names are give first inital, then last name.
+%
+% Likewise, \file{aipauth.dbj} has one line lacking in \file{aipnum.dbj}:
+% \begin{verbatim}
+% nm-rev,%: Surname + comma + initials (Smith, J. F.)
+% \end{verbatim}
+% Thus, the ``author-year'' bibliography is sorted by author name, and
+% names are given last name first, followed by initials.
+%
+% We ensure that the journal substyle has the first word
+% in the matter by installing the (default) AIP code
+% later on (see Section~\ref{sec:aip-defaults}).

+% the most permissive in terms of bibliography and citation style,
+% and it is formatted in two column in the reprint style.

+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\place@bibnumber}
+% \begin{macro}{\@bibstyle}
+% \begin{macro}{\bibpunct}
+% We install code that will
+% govern the style in which \cmd\cite\ commands are
+% formatted,
+% select the presentation for \cmd\bibitem s
+% and control the \BibTeX\ processing.
+%
+% Note that a journal substyle may override these settings.
+% Likewise, document preamble may itself invoke \cmd\bibpunct\ or \cmd\bibliographystyle,
+% thereby overriding these settings and those of the journal substyle.
+%
+% The numbered citations of \file{aipnum} and \file{aipauthnum}
+% are compatible with \classoption{footinbib} and
+% the compression and coalescing features of \classname{natbib},
+% while \file{aipauth}'s author-year citations are not.
+% Therefore, we de-select such options if we are selecting author-year citations.
+%
+% Note on \classname{natbib} presets:
+% \file{aipnum} and \file{aipauthnum} uses the Chicago \cmd\bibpunct\ style;
+% while \file{aipauth} uses that of Nature.
+%
+% Note on \cmd\NAT@mcite: if not using numerical citations, we set \cmd\NAT@mcite\
+% to a lower value, to turn off the mcite semantics of \classname{natbib}.

+% The following may look a bit klootchy, but we

+%
+% Now we declare that
+% these files can only be used with \LaTeXe.
+% An appropriate message is displayed if
+% a different \TeX{} format is used.
+% \begin{macrocode}

+%
+% \section{The driver module \texttt{driver}}
+%
+% This module, consisting of the present section,
+% typesets the programmer's documentation,
+% generating the \file{.ins} installer and \file{README-AIP} as required.
+%
+% Because the only uncommented-out lines of code at the beginning of
+% this file constitute the \file{driver} module itself,
+% we can simply typeset the \file{.dtx} file directly,
+% and there is thus rarely any need to
+% generate the ``driver'' {\sc docstrip} module.
+% Module delimiters are nonetheless required so that
+% this code does not find its way into the other modules.
+%
+% The \enve{document} command concludes the typesetting run.
+%
+% \begin{macrocode}
+%<*driver>
+% \end{macrocode}
+%
+% \subsection{The Preamble}
+% The programmers documentation is formatted
+% with the \classname{ltxdoc} class with local customizations,
+% and with the usual code line indexing.
+% \begin{macrocode}
+\documentclass{ltxdoc}
+\RequirePackage{ltxdocext}%

+\RecordChanges % makeindex -s gglo.ist -o aip.gls aip.glo
+% \end{macrocode}
+%
+% \subsubsection{Docstrip and info directives}
+% We use so many {\sc docstrip} modules that we set the
+% \texttt{StandardModuleDepth} counter to 1.
+% \begin{macrocode}
+\setcounter{StandardModuleDepth}{1}
+% \end{macrocode}
+% The following command retrieves the date and version information
+% from this file.
+% \begin{macrocode}
+\expandafter\GetFileInfo\expandafter{\jobname.dtx}%
+% \end{macrocode}
+%
+% \subsection{The ``Read Me'' File}
+% As promised above, here is the contents of the
+% ``Read Me'' file. That file serves a double purpose,
+% since it also constitutes the beginining of the
+% programmer's documentation. What better thing, after
+% all, to have appear at the beginning of the
+% typeset documentation?
+%
+% A good discussion of how to write a ReadMe file can be found in
+% Engst, Tonya, ``Writing a ReadMe File? Read This''
+% \emph{MacTech} October 1998, p. 58.
+%
+% Note the appearance of the
+% \cmd\StopEventually\ command, which marks the
+% dividing line between the user documentation
+% and the programmer documentation.
+%
+% The usual user will not be asked to
+% do a full build, not to speak
+% of the bootstrap.
+% Instructions for carrying these processes
+% begin the programmer's manual.

+for electronic submissions to AIP journals.
+
+The distribution point for this work is
+\url{http://publishing.aip.org/authors/preparing-your-manuscript}.
+The archive contains ready-to-Install files, documentation, and full source.
+
+This package is also distributed via CTAN:
+\url{http://www.ctan.org/pub/tex-archive/macros/latex/contrib/aip}, and as a ready-to-install image as
+\url{http://www.ctan.org/pub/tex-archive/install/macros/latex/contrib/aip.tds.zip}.
+
+The \classname{aip} package was commissioned by the American Institute of Physics
+and is distributed under the terms of the \LaTeX\ Project Public License,
+the same license under which all the portions of \LaTeX\ itself is distributed.
+Please see \url{http://ctan.tug.org/macros/latex/base/lppl.txt} for details.
+
+To use this document class, you must have a working
+\TeX\ installation equipped with \LaTeXe\
+and possibly pdftex and Adobe Acrobat Reader or equivalent.
+
+To install, retrieve the distribution,
+unpack it into a directory on the target computer,
+and move the file \file{aip.rtx}
+into a location in your filesystem where it will be found by \LaTeX.
+
+To use, read the user documentation \file{auguide.pdf}.
+
+\tableofcontents
+
+\section{Overview}%
+\revtex\ is a \LaTeXe\ document class, somewhat like a hybrid of
+the standard \LaTeX\ \classname{book} and \classname{article} classes.
+
+This document class implements the AIP society and journal substyles:
+the journals represent a set of mutually exclusive class options that, in this case, allow the
+document class to address multiple journals within the AIP family.
+This society is obtained with class option \classoption{aip}.
+
+\section{Processing Instructions}
+
+The package file \file{aip.rtx}
+is generated from this file, \file{aip4-2.dtx},
+using the {\sc docstrip} facility of \LaTeX
+via |tex aip4-2.dtx|.
+The typeset documentation that you are now reading is generated from
+the same file by typesetting it with \LaTeX\ or pdftex
+via |latex aip4-2.dtx| or |pdflatex aip4-2.dtx|.
+
+\subsection{Build Instructions}
+
+You may bootstrap this suite of files solely from \file{aip4-2.dtx}.
+Prepare by installing \LaTeXe\ (and either tex or pdftex) on your computer,
+then carry out the following steps:
+\begin{enumerate}
+\item
+Within an otherwise empty directory,
+typeset \file{aip4-2.dtx} with \LaTeX\ or pdflatex;
+you will obtain the typeset documentation you are now reading,
+along with
+the installer \file{aip.ins},
+and the file \file{README-AIP}.
+
+Note: you will have to run \LaTeX\ twice, then \file{makeindex}, then
+\LaTeX\ again in order to obtain a valid index and table of contents.
+\item
+Now typeset \file{aip4-2.dtx} with \TeX (not \LaTeX),
+thereby generating the package file \file{aip.rtx}.
+\item
+Install \classname{aip.rtx}
+by moving it to a location
+in your filesystem where it will be found by \LaTeX,
+like \file{tex/latex/aip}.
+\item
+Install \classname{aip.pdf}
+by moving it to
+\file{doc/latex/aip}.
+\item
+Using the \file{.dbj} information herein,
+generate the needed \file{.bst} files and install them in
+\file{bibtex/bst/aip}.

+% \section{AIP: A set of journal-specifc extensions to \revtex}
+%
+% To create a journal substyle, you create
+% a \file{.rtx} file, in our case \file{aip.rtx}.
+% Within that file, you override procedures and parameter assignments as you see fit.
+% Ideally they will be generally applicable to all of that society's
+% journals (see the file \file{aps.rtx} for a realization of this scheme).
+% Also within that file, you include a
+% section of code for each journal, that for JMP looks like:
+% \begin{verbatim}
+% \@ifx{\@journal\journal@jmp}{%
+% <code specific to the JMP>
+% }{}%
+% \end{verbatim}
+%
+% \section{The \classoption{aip} class option: the \texttt{aip} module}
+% The file \file{aip.rtx} is read in by the \classname{revtex4} document class
+% if \cmd\@society\ has the value \classoption{aip}.
+%
+% Here, code specific to AIP journals appears.
+%
+% We first give some text entities (amounting to journal abbreviations),
+% then some AIP-specific initialisations,
+% then code for particular AIP journals.
+% In the latter case, the choice is
+% keyed off the macro \cmd\@journal.
+%
+% Note on \cmd\AtEndOfClass:
+% this file, like all journal substyles, is read in at \cmd\AtEndOfClass\ time,
+% so you should not use this command in this file.
+% Note for \LaTeX\ developers: It would be an improvement in \LaTeX\ to
+% \cmd\let\cmd\AtEndOfClass\ to something like \cmd\@firstofone.
+% This change would be effected in \cmd\@onefilewithoptions.

+%
+% The default bibliography style for the AIP journal substyles are \file{aipnum.bst} and \file{aipauth.bst}.
+% To generate them, use \classname{custom-bib} version 4.21 or later.
+% Run the \file{.bst} generator, \file{makebst.tex}, and

+% Between the two files \file{aipnum.dbj} and \file{aipauth.dbj},
+% the differences are limited:
+% \file{aipnum.dbj} has two lines lacking in \file{aipauth.dbj}:
+% \begin{verbatim}
+% seq-no,%: Citation order (unsorted, like unsrt.bst)
+% nm-init,ed-au,%: Initials + surname (J. F. Smith)
+% \end{verbatim}
+% thus, the ``numbered citation'' bibliography is sorted by citation order, and
+% the names are give first inital, then last name.
+%
+% Likewise, \file{aipauth.dbj} has one line lacking in \file{aipnum.dbj}:
+% \begin{verbatim}
+% nm-rev,%: Surname + comma + initials (Smith, J. F.)
+% \end{verbatim}
+% Thus, the ``author-year'' bibliography is sorted by author name, and
+% names are given last name first, followed by initials.
+%
+% We ensure that the journal substyle has the first word
+% in the matter by installing the (default) AIP code
+% later on (see Section~\ref{sec:aip-defaults}).

+% \begin{macro}{\bibpunct}
+% We install code that will
+% govern the style in which \cmd\cite\ commands are
+% formatted,
+% select the presentation for \cmd\bibitem s
+% and control the \BibTeX\ processing.
+%
+% Note that a journal substyle may override these settings.
+% Likewise, document preamble may itself invoke \cmd\bibpunct\ or \cmd\bibliographystyle,
+% thereby overriding these settings and those of the journal substyle.
+%
+% The numbered citations of \file{aipnum} and \file{aipauthnum}
+% are compatible with \classoption{footinbib} and
+% the compression and coalescing features of \classname{natbib},
+% while \file{aipauth}'s author-year citations are not.
+% Therefore, we de-select such options if we are selecting author-year citations.
+%
+% Note on \classname{natbib} presets:
+% \file{aipnum} and \file{aipauthnum} uses the Chicago \cmd\bibpunct\ style;
+% while \file{aipauth} uses that of Nature.
+%
+% Note on \cmd\NAT@mcite: if not using numerical citations, we set \cmd\NAT@mcite\

+% For the documentation and more detailed instructions for
+% installation, typeset this document with \LaTeX.
+% Maintenance Status
+% This work has the LPPL maintenance status "maintained";
+% Current Maintainer of this work is Arthur Ogawa.
+%
+% This work consists of the main source file ltxdocext.dtx
+% and the derived files
+% ltxdocext.sty, ltxdocext.pdf, ltxdocext.ins, ltxdocext.drv.
+% Distribution:
+% CTAN:macros/latex/contrib/revtex/
+%
+% Unpacking:
+% tex ltxdocext.dtx
+%
+% Documentation:
+% latex ltxdocext.dtx; ...
+%
+% Program calls to get the documentation (example):
+% pdflatex ltxdocext.dtx
+% makeindex -s gind.ist ltxdocext.idx
+% makeindex -s gglo.ist -o ltxdocext.gls ltxdocext.glo
+% pdflatex ltxdocext.dtx
+% makeindex -s gind.ist ltxdocext.idx
+% pdflatex ltxdocext.dtx
+%
+% Installation:
+% TDS:doc/latex/revtex/
+% TDS:source/latex/revtex/
+% TDS:tex/latex/revtex/
+%
+% Thanks, Heiko!
+% This method of letting a single .dtx file serve as both
+% documentation (via latex) and installer (via tex) follows
+% the example of Heiko Oberdiek. Thanks!

+% \subsection{Bill of Materials}
+%
+% Following is a list of the files in this distribution arranged
+% according to provenance.
+%
+% \subsubsection{Primary Source}%
+% One single file generates all.
+%\begin{verbatim}
+%ltxdocext.dtx
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{latex ltxdocext.dtx}}%
+% Typesetting the source file under pdflatex
+% generates the readme and the documentation.
+%\begin{verbatim}
+%README ltxdocext.pdf
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{tex ltxdocext.ins}}%
+% Typesetting this file with \TeX\ generates
+% the package file.
+%\begin{verbatim}
+%ltxdocext.sty acrofont.sty
+%\end{verbatim}
+%
+% \subsubsection{Documentation}%
+% The following are the online documentation:
+% \begin{verbatim}
+%ltxdocext.pdf
+% \end{verbatim}
+%
+% \subsubsection{Auxiliary}%
+% The following are auxiliary files generated
+% in the course of running \LaTeX:
+% \begin{verbatim}
+%ltxdocext.aux ltxdocext.idx ltxdocext.ind ltxdocext.log ltxdocext.toc
+% \end{verbatim}
+%
+% \section{Code common to all modules}%
+%
+% We want to require only one place in this file
+% where the version number is stated,
+% and we also want to ensure that the version
+% number is embedded into every generated file.
+%
+% Now we declare that
+% these files can only be used with \LaTeXe.
+% An appropriate message is displayed if
+% a different \TeX{} format is used.
+% \begin{macrocode}
+%<*driver|package|fonts>
+\NeedsTeXFormat{LaTeX2e}[1995/12/01]%
+%</driver|package|fonts>
+% \end{macrocode}
+% As desired, the following modules all
+% take common version information:
+% \begin{macrocode}
+%<package>\ProvidesFile{ltxdocext.sty}%
+%<fonts>\ProvidesFile{acrofont.sty}%
+%<*driver>
+\expandafter\ProvidesFile\expandafter{\jobname.dtx}%
+%</driver>
+% \end{macrocode}
+%
+% The following line contains, for once and for all,
+% the version and date information.
+% By various means, this information is reproduced
+% consistently in all generated files and in the
+% typeset documentation.
+% \begin{macrocode}
+%<version>
+ [2018/12/26/17:10:03 1.0a ltxdoc extensions package]% \fileversion
+% \end{macrocode}
+%
+%
+% \section{The driver module \texttt{doc}}
+%
+% This module, consisting of the present section,
+% typesets the programmer's documentation,
+% generating the \file{README-LTXDOCEXT} as required.
+%
+% Because the only uncommented-out lines of code at the beginning of
+% this file constitute the \file{doc} module itself,
+% we can simply typeset the \file{.dtx} file directly,
+% and there is thus rarely any need to
+% generate the ``doc'' {\sc docstrip} module.
+% Module delimiters are nonetheless required so that
+% this code does not find its way into the other modules.
+%
+% The \enve{document} command concludes the typesetting run.
+%
+% \begin{macrocode}
+%<*driver>
+% \end{macrocode}
+%
+% \subsection{The Preamble}
+% The programmers documentation is formatted
+% with the \classname{ltxdoc} document class, with local customizations,
+% and with the usual code line indexing.
+% \begin{macrocode}
+\documentclass[draft]{ltxdoc}
+\RequirePackage{ltxdocext}%
+\RequirePackage[colorlinks=true,linkcolor=blue]{hyperref}%
+%\expandafter\ifx\csname package@font\endcsname\@undefined\else
+% \expandafter\RequirePackage\expandafter{\csname package@font\endcsname}%
+%\fi
+\CodelineIndex\EnableCrossrefs % makeindex -s gind.ist ltxdocext
+\RecordChanges % makeindex -s gglo.ist -o ltxdocext.gls ltxdocext.glo
+% \end{macrocode}
+%
+% \subsubsection{Docstrip and info directives}
+% We use so many {\sc docstrip} modules that we set the
+% \texttt{StandardModuleDepth} counter to 1.
+% \begin{macrocode}
+\setcounter{StandardModuleDepth}{1}
+% \end{macrocode}
+% The following command retrieves the date and version information
+% from this file.
+% \begin{macrocode}
+\expandafter\GetFileInfo\expandafter{\jobname.dtx}%
+% \end{macrocode}
+%
+% \subsection{The ``Read Me'' File}
+% As promised above, here is the contents of the
+% ``Read Me'' file. That file serves a double purpose,
+% since it also constitutes the beginining of the
+% programmer's documentation. What better thing, after
+% all, to have appear at the beginning of the
+% typeset documentation?
+%

+\maketitle
+
+This file embodies the \classname{ltxdocext} package,
+the implementation and its user documentation.
+
+The distribution point for this work is
+\url{journals.aps.org/revtex},
+which contains prebuilt runtime files, documentation, and full source,
+ready to add to a TDS-compliant \TeX\ installation.
+
+The \classname{ltxdocext} package was commissioned by the American Physical Society
+and is distributed under the terms of the \LaTeX\ Project Public License,
+the same license under which all the portions of \LaTeX\ itself are distributed.
+Please see \url{http://ctan.tug.org/macros/latex/base/lppl.txt} for details.
+
+To use this document class, you must have a working
+\TeX\ installation equipped with \LaTeXe\
+and possibly pdftex and Adobe Acrobat Reader or equivalent.
+
+To install, retrieve the distribution,
+unpack it into a directory on the target computer,
+and move the files \file{ltxdocext.sty} and \file{acrofont.sty}
+into a location in your filesystem where they will be found by \LaTeX.
+
+If you will be using the \classname{acrofont} package, you must
+also install the virtual fonts
+\file{zpsynocmrv}, \file{zptmnocmr},
+\file{zptmnocmrm}, and \file{zpzcnocmry}.
+The corresponding \file{.tfm}, \file{.vf}, and \file{.vpl}
+files are part of this distribution.
+
+To use, read the user documentation \file{ltxdocext.pdf}.
+The \file{.dtx} file, \file{ltxdocext.dtx}, constitutes
+in itself an instance of use of the \classname{ltxdocext}
+package and the \classname{acrofont} package.
+
+\tableofcontents
+
+\section{Processing Instructions}
+
+The package files \file{ltxdocext.sty} and \file{acrofont.sty}
+are generated from this file, \file{ltxdocext.dtx},
+using the {\sc docstrip} facility of \LaTeX
+via |tex ltxdocext.dtx| (Note: do \emph{not} use \LaTeX\ for this step).
+The typeset documentation that you are now reading is generated from
+the same file by typesetting it with \LaTeX\ or pdftex
+via |latex ltxdocext.dtx| or |pdflatex ltxdocext.dtx|.
+
+\subsection{Build Instructions}
+
+You may bootstrap this suite of files solely from \file{ltxdocext.dtx}.
+Prepare by installing \LaTeXe\ (and either tex or pdftex) on your computer,
+then carry out the following steps:
+\begin{enumerate}
+\item
+Within an otherwise empty directory,
+typeset \file{ltxdocext.dtx} with \TeX\ or pdftex;
+thereby generating the package file \file{ltxdocext.sty},
+and the package file \file{acrofont.sty}.
+Make sure that {\sc docstrip} receives permission
+to overwrite existing versions of these packages.
+\item
+Now
+typeset \file{ltxdocext.dtx} with \LaTeX\ or pdflatex;
+you will obtain the typeset documentation you are now reading,
+along with
+the file \file{README}.
+
+Note: you will have to run \LaTeX, then
+\file{makeindex} \texttt{-s gind.ist ltxdocext.idx}, then
+\file{makeindex} \texttt{-s gglo.ist -o ltxdocext.gls ltxdocext.glo}, then
+\LaTeX\ again in order to obtain a valid index and table of contents.
+\item
+Install the following files into indicated locations within your
+TDS-compliant \texttt{texmf} tree (you may need root access):
+\begin{itemize}
+\item
+\file{$TEXMF/}\file{tex/}\file{latex/}\file{revtex/}\classname{ltxdocext.sty} and
+\file{$TEXMF/}\file{tex/}\file{latex/}\file{revtex/}\classname{acrofont.sty}
+\item
+\file{$TEXMF/}\file{source/}\file{latex/}\file{revtex/}\classname{ltxdocext.dtx}
+\item
+\file{$TEXMF/}\file{doc/}\file{latex/}\file{revtex/}\classname{ltxdocext.pdf}
+\end{itemize}
+where \file{$TEXMF/} stands for \file{texmf-local/}, or some other \texttt{texmf} tree
+in your installation.
+\item
+Run \texttt{mktexlsr} on \file{$TEXMF/} (you may need root access).
+\item
+Build and installation are now complete;
+now put a \cmd\usepackage\texttt{\{ltxutil\}} in your document preamble!
+\end{enumerate}

+%
+% \subsection{The Document Body}
+%
+% Here is the document body, containing only a
+% \cmd\DocInput\ directive---referring to this very file.
+% This very cute self-reference is a common \classname{ltxdoc} idiom.
+% \begin{macrocode}
+\begin{document}%
+\expandafter\DocInput\expandafter{\jobname.dtx}%
+\PrintChanges
+\end{document}
+%</driver>
+% \end{macrocode}
+%
+% \section{Using the \classname{ltxdoc} and \classname{acrofont} packages}%
+% These packages are an adjunct to the
+% standard \LaTeX\ \classname{ltxdoc} class and may be
+% simply invoked as follows:
+%\begin{verbatim}
+%\documentclass[draft]{ltxdoc}
+%\RequirePackage{ltxdocext}%
+%\RequirePackage{acrofont}%
+%\CodelineIndex\EnableCrossrefs
+%\end{verbatim}
+%
+% Your document should simply cleave to the standards of the
+% \classname{ltxdoc} class, with extensions and alterations as noted.
+%
+% \subsection{Extensions to the \classname{ltxdoc} class}%
+%
+% \subsubsection{Extensions to the \env{verbatim} environment and \cs{verb} command}%
+%
+% The delimiters \verb$<<$ and \verb$>>$ within the scope of the verbatim environment
+% or within the argument of the \cmd\verb\ command produce
+% italics surrounded by angle brackets.
+% This typographic convention usually indicates
+% \emph{metalanguage}, i.e., a placeholder.
+%
+% To obtain the angle bracket character per se,
+% double the character, viz., ``\verb$the delimiter \verb+<<<<+$''.
+%
+% \subsubsection{The -\texttt{matter} Commands Work}
+% The sectioning commands \cmd\frontmatter, \cmd\mainmatter, and \cmd\backmatter
+% of the standard \LaTeX\ \classname{book} class are operative in the
+% \classname{ltxdoc} class.
+%
+% \subsubsection{The \cs{GetFileInfo} command}\label{sec:GetFileInfo}
+% You can use the \cmd\GetFileInfo\ command to extract
+% the date, version, and file info of a file which has registered itself
+% via the \cmd\ProvidesFile\ or \cmd\ProvidesClass\ command
+% (employing the optional argument thereto).
+%
+% For instance, if your document contains the following:
+%\begin{verbatim}
+%\RequirePackage{ltxdocext}%
+%\GetFileInfo{ltxdocext.sty}%
+%\end{verbatim}
+% then the following control sequence names will have
+% a value corresponding to that package's \cmd\ProvidesFile\
+% command:
+% \cmd\filedate: the file's date,
+% \cmd\fileversion: the file's version, and
+% \cmd\fileinfo: the file's info.
+%
+% \subsubsection{Self-Indexing Commands}%
+% Certain commands automatically produce an index entry
+% (or several related entries) according to the meaning.
+%
+% \begin{unnumtable}
+% \begin{tabular}{ll}
+% meta-text &\cmd\marg\arg{text}\\
+% command &\cmd\cmd\cmd\csname\\
+% environment name &\cmd\env\arg{name}\\
+% \cmd\begin\verb`{foo}`&\cmd\envb\arg{foo}\\
+% \cmd\end\verb`{foo}` &\cmd\enve\arg{foo}\\
+% argument &\cmd\arg\arg{name}\\
+% optional &\cmd\oarg\arg{name}\\
+% filename &\cmd\file\arg{name}\\
+% url &\cmd\url\arg{name}\\
+% document class &\cmd\classname\arg{name}\\
+% document substyle &\cmd\substyle\arg{name}\\
+% class option &\cmd\classoption\arg{name}
+% \end{tabular}
+% \end{unnumtable}
+%
+% \subsubsection{Unnumbered Tables}%
+%
+% When your documentation requires the use of an unnumbered table,
+% use the \env{unnumtable} environment:
+% \begin{verbatim}
+%\begin{unnumtable}
+%\begin{tabular}{ll}
+%<table rows>
+%\end{tabular}
+%\end{unnumtable}
+% \end{verbatim}
+%
+% \subsubsection{Structuring Tables}%
+% The commands \cmd\toprule, \cmd\colrule, and \cmd\botrule
+% allow you to mark the beginning of the column heads
+% the beginning of the table body, and the end of
+% the table body, respectively.
+% In context,
+% \begin{verbatim}
+%\begin{tabular}{ll}
+%\toprule
+%<table head rows>
+%\colrule
+%<table rows>
+%\botrule
+%\end{tabular}
+% \end{verbatim}
+%
+% \subsubsection{A Sectioning Command Below \cs{subsection}}%
+% The \cmd\subsubsection\ command is defined.
+%
+%
+% \subsection{Alterations to the \classname{ltxdoc} class}%
+% The following involve no new markup, but they
+% do change the appearance of your formatted documentation:
+% \begin{enumerate}
+% \item
+% Using the \classname{acrofont} package causes your
+% document to be formatted using the standard
+% Acrobat fonts to the greatest extent possible.
+% This means that for most documents, Computer Modern
+% is not used at all.
+% Math that unavoidable must use CM still exists, however.
+% \item
+% An index will be produced at the end of the document
+% without your needing to explicitly mark it up, and
+% it will have an entry in the TOC.
+% \item
+% The \env{quote} environment has a slightly smaller left margin.
+% \item
+% Array columns are set tight by default.
+% \item
+% A host of \cmd\DoNotIndex\ directives are invoked.
+% I intend this list to grow to encompass
+% even more commands. Send me your suggestions.
+% \end{enumerate}
+%
+%
+%

+%
+% \section{Extensions to the ltxdoc class}
+% The \file{package} {\sc docstrip} module comprises the
+% package \classname{ltxdocext.sty}, which provides extensions
+% to the standard \LaTeX\ \classname{ltxdoc} class.
+%
+% \subsection{Beginning of the \file{package} {\sc docstrip} module}
+% This portion of code is only present in the \LaTeX\ package (\texttt{.sty} file),
+% not in the kernel portion.
+% \begin{macrocode}

+% \end{macrocode}
+%
+% \subsection{Beginning of the \file{kernel} {\sc docstrip} module}
+%
+% The bulk of the code is the kernel portion; a brief tail of \file{package} code then follows.
+% \begin{macrocode}
+%<*kernel>

+%
+% \subsection{Incorporate \classname{ltxguide.cls} extensions}
+%
+% Code extracted from \classname{ltxguide.cls}, by Alan Jeffrey.
+% ``This code stolen from \classname{ltxguide.cls}:
+% Some hacks with verbatim... NB: this would be better done with the

+%
+% Make active bracket characters produce italics surrounded by angle brackets
+% (used in \env{verbatim} and \cmd\verb).
+% \verb|<<| produces a less-than, and \verb|>>| produces a greater-than.

+%
+% \section{Font Package for Acrobat Compatability}%
+% The package \classname{acrofont}
+% substitutes Acrobat-standard fonts for Computer Modern where possible,
+% even in math mode.
+% Documents typeset with this package in effect will require as little
+% downloaded font data as possible, but will not be exemplars of
+% fine math typesetting.
+%
+% \subsection{Beginning of the \file{fonts} {\sc docstrip} module}
+% The document class module comprises this and the next
+% four sections.
+% \begin{macro}{\class@base}
+% We define in exactly one spot the base class.
+% Typically that class will be one of \classname{book},
+% \classname{article}, or \classname{report}.
+% The base class effectively defines the use and the markup scheme
+% of the class of documents to be handled by this class.
+%
+% This class is a variant of the standard \LaTeX\ book class:
+% \url{ftp://ctan.tug.org/tex-archive/macros/latex/unpacked}.

+%
+% \subsection{Variants on psfonts packages}%
+% The following uses \file{times.sty} from \url{/packages/psnfss/psfonts.dtx}
+% \begin{macrocode}
+\RequirePackage{times}%
+% \end{macrocode}
+%
+% The following uses \file{mathptm.sty} from \url{/packages/psnfss/psfonts.dtx}
+% \begin{macrocode}
+\RequirePackage{mathptm}%
+% \end{macrocode}
+%
+% The following is a customization of \file{ot1ptmcm.fd}.
+% The virtual font referred to here \file{zptmnocmr} is
+% a variant of Sebastian Rahtz's \file{zptmcmr}, but with
+% even more glyphs moved from CM to Acrobat-standard fonts.
+% \begin{macrocode}
+\DeclareFontFamily{OT1}{ptmcm}{}
+\DeclareFontShape{OT1}{ptmcm}{m}{n}{
+ <-> zptmnocmr
+}{}
+\DeclareFontShape{OT1}{ptmcm}{l}{n}{<->ssub * ptmnocm/m/n}{}
+% \end{macrocode}
+%
+% The following is a customization of \file{omlptmcm.fd}
+% The virtual font referred to here \file{zptmnocmrm} is
+% a variant of Sebastian Rahtz's \file{zptmcmrm}, but with
+% even more glyphs moved from CM to Acrobat-standard fonts.
+% \begin{macrocode}
+\DeclareFontFamily{OML}{ptmcm}{\skewchar \font =127}

+%
+% The following is a customization of \file{omspzccm.fd}
+% The virtual font referred to here \file{zpzcnocmry} is
+% a variant of Sebastian Rahtz's \file{zpzccmry}, but with
+% even more glyphs moved from CM to Acrobat-standard fonts.
+% \begin{macrocode}

+\DeclareFontShape{8r}{cmr}{m}{n}{
+ <-> cmr10
+}{}
+% \end{macrocode}
+%
+% \subsection{Font definition files}%
+%
+% The following forces \LaTeX\ to do now what it would do anyway:
+% load the `font definition' information for the fonts that we
+% use. In this way, we prepare for faster processing through
+% the \cmd\dump\ of a preformatted macro package that will not
+% need to read in any packages or font definitions from disk.
+% \begin{macrocode}
+\input{8rphv.fd}%
+\input{8rptm.fd}%
+\input{ot1phv.fd}%
+\input{ot1ptm.fd}%
+\input{t1ptm.fd}%
+% \end{macrocode}
+%
+% \subsection{More math substitutions}%
+%
+% The following definitions arrange to get certain glyphs from the
+% text font instead of out of math pi fonts.
+% In particular, the copyright and registered symbols
+% are single glyphs instead of composites involving
+% the big circle from the \file{cmsy} font.
+% \begin{macrocode}
+ \def\eightRChar#1{{\def\encodingdefault{8r}\fontencoding\encodingdefault\selectfont\char"#1}}%
+ \def\LANGLE{$<$}%{\eightRChar{8B}}%
+ \def\RANGLE{$>$}%{\eightRChar{9B}}%
+%\def\ASTER{\eightRChar{2A}}%
+%\def\DAGGER{\eightRChar{86}}%
+%\def\DDAGGER{\eightRChar{87}}%
+ \def\BULLET{\eightRChar{95}}%
+%\def\SECTION{\eightRChar{A7}}%
+%\def\PARAGRAPH{\eightRChar{B6}}%
+ \def\VERTBAR{\eightRChar{7C}}%
+ \def\COPYRIGHT{\eightRChar{A9}}%
+ \def\REGISTERED{\eightRChar{AE}}%
+% \end{macrocode}
+%
+% \begin{macrocode}
+ \def\textbar{\VERTBAR}%
+ \def\textbullet{\BULLET}%
+ \def\textcopyright{\COPYRIGHT}%
+ \def\textregistered{\REGISTERED}%
+% \end{macrocode}
+%
+% I have removed \cmd\ensuremath\ from the following definition, and
+% all commands like \cmd\mathsection have been converted to
+% e.g., \cmd\textsection.
+% \begin{macrocode}
+\def\@makefnmark{\@thefnmark}%
+\def\@fnsymbol#1{{\ifcase#1\or *\or \dagger\or \ddagger\or
+ \textsection\or \textparagraph\or \|\or **\or \dagger\dagger
+ \or \ddagger\ddagger \else\@ctrerr\fi}}
+% \end{macrocode}
+%
+% \subsection{End of the \file{fonts} {\sc docstrip} module}
+% Here ends the module.
+% \begin{macrocode}
+%</fonts>
+% \end{macrocode}
+%
+%
+% \section{Programming Conventions}%
+% In writing the above code, I cleave to certain conventions, noted
+% here.
+% My goal in explaining them is to encourage others maintaining this
+% body of code to consider following them as well.
+% The benefits are twofold:
+% Some of the coding conventions aim to avoid programming pitfalls;
+% following them reduces maintenance costs.
+% Others make the code easier to read; following these eases the
+% process of understanding how the code works.
+%
+% And, for my part, I prefer to read code of this type.
+%
+% \subsection{Whitespace Conventions}%
+% Exactly where code lines break and indent, and where additional
+% whitespace is inserted is explained here.
+% \begin{itemize}
+% \item
+% Each new macro definition or register assignment begins a new line.
+% Therefore, \cmd\def, \cmd\newcommand, and their ilk will start in column~1.
+% \item
+% Code is indented one space for each level of nesting within braces
+% \verb|{}|.
+% \item
+% Likewise, if possible, for \cmd\if\dots and matching \cmd\fi.
+% \item
+% However, the closing brace or \cmd\fi\ is outdented by one so that it
+% falls
+% at the same level of indentation as its matching brace or \cmd\if,
+% and it appears alone on its line.
+% \item
+% Use of the |tab| character is deprecated
+% (tabs are not standardized across all applications and operating
+% systems).
+% \item
+% Lines of code are limited to 72 characters.
+% I follow this convention mostly to ease the transmission of files
+% via email (a deprecated practice) and to accomodate people with
+% small monitors.
+% But \classname{ltxdoc} output looks better with the shorter lines, too.
+% \item
+% Extraneous whitespace in the replacement part of a macro definition
+% is avoided by using the comment character |%|.
+% In most cases, if falling at the end of a line of code,
+% a brace will be immediately followed by a comment character,
+% as will the macro parameter |#1| and any one-letter control sequence,
+% like |\\|.
+% \item
+% Extraneous whitespace in the package file is also avoided.
+% When \TeX\ reads in the .sty file, it will process \cmd\def s, and other commands,
+% but will not process blank spaces.
+% This practice is simply a discipline. You don't need to do this.
+% But sometimes \TeX\ has to read in a file while it is in horizontal mode,
+% at which point this practice is essential.
+% \end{itemize}
+% These conventions taken together are illustrated by the following:
+% \begin{verbatim}
+%\def\prepdef#1#2{%
+% \@ifxundefined#1{\toks@{}}{\toks@\expandafter{#1}}%
+% \toks@ii{#2}%
+% \edef#1{\the\toks@ii\the\toks@}%
+%}%
+% \end{verbatim}
+% In the above, the definition of \cmd\prepdef\ would not fit on a single
+% line,
+% and required breaking. The first and last lines have matching braces,
+% and are a the same level of indentation, with the last line containing
+% a single brace.
+%
+% Each of the three intervening lines has balanced braces and is
+% indented by one space. Each line that would otherwise end in a single
+% brace character is terminated by a comment character.
+%
+% Some coders rely on the fact that a space character seen by \TeX's
+% scanner while in vertical mode is a no-op.
+% Be that as it may, I eliminate them unless actually intentional.
+%
+% \subsection{Conventions For Procedures}%
+% Here are some of my preferences when writing procedures:
+% \begin{itemize}
+%
+% \item
+% I dislike defining a macro within another macro, especially when the
+% pattern part is non-nil.
+% You know, you are not saving much space in |mem| when you do this,
+% right?
+% You do save space in the hash table and the string pool, though.
+% On the other hand, we are not dealing with small \TeX\ engines
+% anymore; Team \LaTeX\ has made sure of this.
+%
+% \item
+% If two or more macros have very similar replacement parts, consider
+% layering.
+%
+% \item
+% Macros may perform parsing, may maintain tokens or registers, or may
+% set type (produce marks). I try to avoid combining the three functions
+% in a single macro.
+%
+% \item
+% When a procedure both does assignments and sets type, I try to have a
+% clean separations between the two activities. Try to avoid:
+% \begin{verbatim}
+% \vskip10pt
+% \parindent=0pt
+% \leavevmode
+% \end{verbatim}
+%
+% \item
+% The Boolean calculus (cf. \cmd\@ifx)
+% is very useful and produces code that executes nicely.
+% Using it also helps avoid your having to debug problems where
+% \cmd\if\dots\ and \cmd\fi\ are not properly balanced
+% (a nightmare, in case you have not already experienced it).
+%
+% \end{itemize}
+%
+% \subsection{Conventions For \LaTeX}%
+% Team \LaTeX\ make certain recommendations in \file{clsguide.tex}.
+% Ones that I particularly pay attention to are:
+% \begin{itemize}
+%
+% \item
+% For the sake of ``color safety'',
+% use \cmd\sbox\ rather than \cmd\setbox, \cmd\mbox\ rather than \cmd\hbox, and
+% \cmd\parbox\ or \env{minipage} rather than \cmd\vbox.
+%
+% \item
+% Use \cmd\newcommand\ and \cmd\newenvironment\ to declare user-level commands
+% and environments. Avoid the idiom \cmd\def\cmd\foo, \cmd\def\cmd\endfoo\ to define
+% an environment.
+% Ideally, all user-level markup could be extracted from the
+% document class by grepping on \cmd\newcommand\ and \cmd\newenvironment.
+%
+% \item
+% Prefer to use \cmd\setlength\ to assign registers.
+%
+% \end{itemize}
+% I cannot help but notice that much of the code of \LaTeX\ itself fails
+% to comply with many of the coding recommendations of Team \LaTeX.
+%
+% \Finale

+%
+% \section{Code common to all modules}%
+%
+% We want to require only one place in this file
+% where the version number is stated,
+% and we also want to ensure that the version
+% number is embedded into every generated file.
+%
+% Now we declare that
+% these files can only be used with \LaTeXe.

+%
+%
+% \section{The doc module \texttt{doc}}
+%
+% This module, consisting of the present section,
+% typesets the programmer's documentation,
+% generating the \file{README-LTXFRONT} and sample document as needed.
+%
+% Because the only uncommented-out lines of code at the beginning of
+% this file constitute the \file{doc} module itself,
+% we can simply typeset the \file{.dtx} file directly,
+% and there is thus rarely any need to
+% generate the ``doc'' {\sc docstrip} module.
+% Module delimiters are nonetheless required so that
+% this code does not find its way into the other modules.
+%
+% The \enve{document} command concludes the typesetting run.
+%
+% \begin{macrocode}
+%<*doc>
+% \end{macrocode}
+%
+% \subsection{The Preamble}
+% The programmers documentation is formatted
+% with the \classname{ltxdoc} class with local customizations,
+% and with the usual code line indexing.
+% \begin{macrocode}
+\documentclass{ltxdoc}
+\RequirePackage{ltxdocext}%

+\CodelineIndex\EnableCrossrefs % makeindex -s gind.ist ltxfront
+\RecordChanges % makeindex -s gglo.ist -o ltxfront.gls ltxfront.glo
+% \end{macrocode}
+%
+% \subsubsection{Docstrip and info directives}
+% We use so many {\sc docstrip} modules that we set the
+% \texttt{StandardModuleDepth} counter to 1.
+% \begin{macrocode}
+\setcounter{StandardModuleDepth}{1}
+% \end{macrocode}
+% The following command retrieves the date and version information
+% from this file.
+% \begin{macrocode}
+\expandafter\GetFileInfo\expandafter{\jobname.dtx}%
+% \end{macrocode}
+%
+% \subsection{The ``Read Me'' File}
+% As promised above, here is the contents of the
+% ``Read Me'' file. That file serves a double purpose,
+% since it also constitutes the beginining of the
+% programmer's documentation. What better thing, after
+% all, to have appear at the beginning of the
+% typeset documentation?
+%
+% A good discussion of how to write a ReadMe file can be found in
+% Engst, Tonya, ``Writing a ReadMe File? Read This''
+% \emph{MacTech} October 1998, p. 58.
+%
+% Note the appearance of the
+% \cmd\StopEventually\ command, which marks the
+% dividing line between the user documentation
+% and the programmer documentation.
+%
+% The usual user will not be asked to
+% do a full build, not to speak
+% of the bootstrap.
+% Instructions for carrying these processes
+% begin the programmer's manual.

+\maketitle
+
+This file embodies the \classname{ltxfront} package,
+the implementation and its user documentation.
+
+The distribution point for this work is
+\url{https://journals.aps.org/revtex},
+which contains fully unpacked, prebuilt runtime files and documentation.
+
+The \classname{ltxfront} package was commissioned by the American Physical Society
+and is distributed under the terms of the \LaTeX\ Project Public License 1.3c,
+the same license under which all the portions of \LaTeX\ itself is distributed.
+Please see \url{http://ctan.tug.org/macros/latex/base/lppl.txt} for details.
+
+To use this document class, you must have a working
+\TeX\ installation equipped with \LaTeXe\
+and possibly pdftex and Adobe Acrobat Reader or equivalent.
+
+To install, retrieve the distribution,
+unpack it into a directory on the target computer,
+and move the file \file{ltxfront.sty}
+into a location in your filesystem where it will be found by \LaTeX.
+
+To use, read the user documentation \file{ltxfront.pdf}.
+
+\tableofcontents
+
+\section{Processing Instructions}
+
+The package file \file{ltxfront.sty}
+is generated from this file, \file{ltxfront.dtx},
+using the {\sc docstrip} facility of \LaTeX
+via |tex ltxfront.dtx|.
+The typeset documentation that you are now reading is generated from
+the same file by typesetting it with \LaTeX\ or pdftex
+via |latex ltxfront.dtx| or |pdflatex ltxfront.dtx|.
+
+\subsection{Build Instructions}
+
+You may bootstrap this suite of files solely from \file{ltxfront.dtx}.
+Prepare by installing \LaTeXe\ (and either tex or pdftex) on your computer,
+then carry out the following steps:
+\begin{enumerate}
+
+\item
+Within an otherwise empty directory,
+typeset \file{ltxfront.dtx} with \TeX\ or pdftex,
+thereby generating the package file \file{ltxfront.sty}.
+
+\item
+Next typeset \file{ltxfront.dtx} with \LaTeX\ or pdflatex;
+you will obtain the typeset documentation you are now reading,
+along with
+the sample document \file{ltxfront-test.tex}
+and the file \file{README-LTXFRONT}.
+
+Note: you will have to run \LaTeX, then
+\file{makeindex} \texttt{-s gind.ist ltxfront.idx}, then
+\file{makeindex} \texttt{-s gglo.ist -o ltxfront.gls ltxfront.glo}, then
+\LaTeX\ again in order to obtain a valid index and table of contents.
+\item
+Now typeset \file{ltxfront.dtx} with \TeX (not \LaTeX),
+thereby generating the package file \file{ltxfront.sty}.
+\item
+Install the following files into indicated locations within your
+TDS-compliant \texttt{texmf} tree (you may need root access):

+% \section{Using this package}
+% Once this package is installed on your filesystem, you can employ it in
+% adding functionality to \LaTeX\ by invoking it in your document or document class.
+%
+% \subsection{Invoking the package}
+% In your document, you can simply call it up in your preamble:
+% \begin{verbatim}
+%\documentclass{book}%
+%\usepackage{ltxfront}%
+%\begin{document}
+%<your document here>
+%\end{document}\end{verbatim}
+% However, the preferred way is to invoke this package from within your
+% customized document class:
+% \begin{verbatim}
+%\NeedsTeXFormat{LaTeX2e}[1995/12/01]%
+%\ProvidesClass{myclass}%
+%\RequirePackage{ltxfront}%
+%\LoadClass{book}%
+%<class customization commands>
+%\endinput\end{verbatim}
+%
+% Once loaded, the package gives you acccess to certain procedures,
+% usually to be invoked by a \LaTeX\ command or environment.
+%
+% \section{Frontmatter commands}
+%
+% A document using this package will use commands like \cmd\title, \cmd\author, \cmd\thanks,
+% the \texttt{abstract} environment
+% and \cmd\maketitle.
+% These are part of \LaTeX's standard document classes.
+% But this package supplements \LaTeX\ syntax with additional commands, such as
+% \cmd\affiliation, \cmd\collaboration, \cmd\email, \cmd\homepage, and others.
+%
+% Furthermore, you can have multiple \cmd\author, \cmd\affiliation, and \cmd\collaboration\ commands,
+% each with their own set of \cmd\email, \cmd\homepage, etc. commands.
+%
+% \section{The Front Matter}\label{sec:front}
+%
+% This section describes the macros
+% this package provides for formatting the front matter of an
+% article. The behavior and usage of these macros can be quite
+% different from those provided in \LaTeXe.
+%
+% \subsection{Setting the title}
+%
+% The title of the manuscript is simply specified by using the
+% \cmd\title\arg{title} macro. A \verb+\\+ may be used to put a line
+% break in a long title.
+% The \cmd\title\ commnd takes an optional argument, which you will use to
+% give an abbreviated title for use in the running header.
+%
+% \subsection{Specifying a date}%
+%
+% The \cmd\date\marg{date} command outputs the date on the manuscript.
+% Using \cmd\today\ will cause \LaTeX{} to insert the
+% current date whenever the file is run:
+% \begin{verbatim}\date{\today}\end{verbatim}
+%
+% \subsection{Specifying authors and affiliations}
+%
+% Commands specifying author and affilliation have been improved to save
+% labor for authors and in production. Authors and affiliations are
+% arranged into groupings called, appropriately enough, \emph{author
+% groups}. Each author group is a set of authors who share the same set
+% of affiliations. Author names are specified with the \cmd\author\
+% macro while affiliations (or addresses) are specified with the
+% \cmd\affiliation\ macro. Author groups are specified by sequences of
+% \cmd\author\ macros followed by \cmd\affiliation\ macros. An
+% \cmd\affiliation\ macro applies to all previously specified
+% \cmd\author\ macros which don't already have an affiliation supplied.
+%
+% For example, if Bugs Bunny and Roger Rabbit are both at Looney Tune
+% Studios, while Mickey Mouse is at Disney World, the markup would be:
+% \begin{verbatim}
+% \author{Bugs Bunny}
+% \author{Roger Rabbit}
+% \affiliation{Looney Tune Studios}
+% \author{Mickey Mouse}
+% \affiliation{Disney World}\end{verbatim}
+% The default is to display this as
+% \begin{center}
+% Bugs Bunny and Roger Rabbit\\
+% \emph{Looney Tune Studios}\\
+% Mickey Mouse\\
+% \emph{Disney World}\\
+% \end{center}
+% This layout style for displaying authors and their affiliations is
+% chosen by selecting the class option
+% \classoption{groupedaddress}. This option is the default for all APS
+% journal styles, so it does not need to be specified explicitly.
+% The other major way of displaying this
+% information is to use superscripts on the authors and
+% affiliations. This can be accomplished by selecting the class option
+% \classoption{superscriptaddress}. To achieve the display
+% \begin{center}
+% Bugs Bunny,$^{1}$ Roger Rabbit,$^{1,2}$ and Mickey Mouse$^{2}$\\
+% \emph{$^{1}$Looney Tune Studios}\\
+% \emph{$^{2}$Disney World}\\
+% \end{center}
+% one would use the markup
+% \begin{verbatim}
+% \author{Bugs Bunny}
+% \affiliation{Looney Tune Studios}
+% \author{Roger Rabbit}
+% \affiliation{Looney Tune Studios}
+% \affiliation{Disney World}
+% \author{Mickey Mouse}
+% \affiliation{Disney World}\end{verbatim}
+%
+% Note that this package takes care of any commas and \emph{and}'s that join
+% the author names together and font selection, as well as any
+% superscript numbering. Only the author names and affiliations should
+% be given within their respective macros.
+%
+% There is a third class option, \classoption{unsortedaddress}, for
+% controlling author/affiliation display. The default
+% \classoption{groupedaddress} will actually sort authors into the
+% approriate author groups if one chooses to specify an affiliation for
+% each author. The markup:
+% \begin{verbatim}
+% \author{Bugs Bunny}
+% \affiliation{Looney Tune Studios}
+% \author{Mickey Mouse}
+% \affiliation{Disney World}
+% \author{Roger Rabbit}
+% \affiliation{Looney Tune Studios}\end{verbatim}
+% will result in the same display as for the first case given
+% above even though Roger Rabbit is specified after Mickey Mouse. To
+% avoid Roger Rabbit being moved into the same author group as Bugs
+% Bunny, use the
+% \classoption{unsortedaddress} option instead. In general, it is safest
+% to list authors in the order they should appear and specify
+% affiliations for multiple authors rather than one at a time. This will
+% afford the most independence for choosing the display option. Finally,
+% it should be mentioned that the affiliations for the
+% \classoption{superscriptaddress} are presented and numbered
+% in the order that they are encountered. This means that the order
+% will usually follow the order of the authors. An alternative ordering
+% can be forced by including a list of \cmd\affiliation\ commands before
+% the first \cmd{\author} in the desired order. Then use the exact same
+% text for each affilation when specifying them for each author.
+%
+% If an author doesn't have an affiliation, the \cmd\noaffiliation\
+% macro may be used in the place of an \cmd\affiliation\ macro.
+%
+%
+% \subsubsection{Collaborations}
+%
+% A collaboration name can be specified with the \cmd\collaboration\
+% command. This is very similar to the \cmd\author\ command.
+% It should appear at the end of an author group.
+% The collaboration name will appear centered in parentheses.
+% You may have multiple author groups, each with its own \cmd\collaboration.
+% Because collaborations don't normally have affiliations, one needs to follow the
+% \cmd\collaboration\ with \cmd\noaffiliation.
+%
+% \subsubsection{Footnotes for authors, collaborations, affiliations or title}\label{sec:footau}
+%
+% Often one wants to specify additional information associated with an
+% author, collaboration, or affiliation such an e-mail address, an
+% alternate affiliation, or some other ancillary information.
+% This package introduces several new macros just for this purpose. They
+% are:
+% \begin{itemize}
+% \item\cmd\email\oarg{optional text}\arg{e-mail address}
+% \item\cmd\homepage\oarg{optional text}\arg{URL}
+% \item\cmd\altaffiliation\oarg{optional text}\arg{affiliation}
+% \item\cmd\thanks\arg{miscellaneous text}
+% \end{itemize}
+% In the first three, the \emph{optional text} will be prepended before the
+% actual information specified in the required argument. \cmd\email\ and
+% \cmd\homepage\ each have a default text for their optional arguments
+% (`Electronic address:' and `URL:' respectively). The \cmd\thanks\
+% macro should only be used if one of the other three do not apply. Any
+% author name can have multiple instances of these four commands.
+% Note that unlike the
+% \cmd\affiliation\ macro, these macros only apply to the \cmd\author\
+% that directly precedes it. Any \cmd\affiliation\ \emph{must} follow
+% the other author-specific macros. A typical usage might be as follows:
+% \begin{verbatim}
+% \author{Bugs Bunny}
+% \email[E-mail me at: ]{bugs@looney.com}
+% \homepage[Visit: ]{http://looney.com/}
+% \altaffiliation[Permanent address: ]
+% {Warner Brothers}
+% \affiliation{Looney Tunes}\end{verbatim}
+% This would result in the footnote ``E-mail me at: \texttt{bugs@looney.com},
+% Visit: \texttt{http://looney.com/}, Permanent address: Warner
+% Brothers'' being attached to Bugs Bunny. Note that:
+% \begin{itemize}
+% \item Only an e-mail address, URL, or affiliation should go in the
+% required argument in the curly braces.
+% \item The font is automatically taken care of.
+% \item An explicit space is needed at the end of the optional text if one is
+% desired in the output.
+% \item Use the optional arguments to provide customized
+% text only if there is a good reason to.
+% \end{itemize}
+%
+% The \cmd\collaboration\ , \cmd\affiliation, or even \cmd\title\ can
+% also have footnotes attached via these commands. If any ancillary data
+% (\cmd\thanks, \cmd\email, \cmd\homepage, or
+% \cmd\altaffiliation) are given in the wrong context (e.g., before any
+% \cmd\title, \cmd\author, \cmd\collaboration, or \cmd\affiliation\
+% command has been given), then a warning is given in the \TeX\ log, and
+% the command is ignored.
+%
+% Duplicate sets of ancillary data are merged, giving rise to a single
+% shared footnote. However, this only applies if the ancillary data are
+% identical: even the order of the commands specifying the data must be
+% identical. Thus, for example, two authors can share a single footnote
+% indicating a group e-mail address.
+%
+% Duplicate \cmd\affiliation\ commands may be given in the course of the
+% front matter, without the danger of producing extraneous affiliations
+% on the title page. However, ancillary data should be specified for
+% only the first instance of any particular institution's
+% \cmd\affiliation\ command; a later instance with different ancillary
+% data will result in a warning in the \TeX\ log.
+%
+% It is preferable to arrange authors into
+% sets. Within each set all the authors share the same group of
+% affiliations. For each author, give the \cmd\author\ (and appropriate
+% ancillary data), then follow this author group with the needed group
+% of \cmd\affiliation\ commands.
+%
+% If affiliations have been listed before the first
+% \cmd\author\ macro to ensure a particular ordering, be sure
+% that any later \cmd\affiliation\ command for the given institution is
+% an exact copy of the first, and also ensure that no ancillary data is
+% given in these later instances.
+%
+%
+% A journal may determine the placement of these
+% ancillary information footnotes. One journal may put all
+% such footnotes at the start of the bibliography while another
+% journal may display them on the first page, as a footnote. One can override a
+% journal style's default behavior by specifying explicitly the class
+% option
+% \classoption{bibnotes} (puts the footnotes at the start of the
+% bibliography) or \classoption{nobibnotes} (puts them on the first page).
+%
+% \subsubsection{Specifying first names and surnames}
+%
+% Many authors have names in which either the surname appears first
+% or in which the surname is made up of more than one name. To ensure
+% that such names are accurately captured for indexing and other
+% purposes, the \cmd\surname\ macro should be used to indicate which portion
+% of a name is the surname. Similarly, there is a \cmd\firstname\ macro
+% as well, although usage of \cmd\surname\ should be sufficient. If an
+% author's surname is a single name and written last, it is not
+% necessary to use these macros. These macros do nothing but indicate
+% how a name should be indexed. Here are some examples;
+% \begin{verbatim}
+% \author{Andrew \surname{Lloyd Weber}}
+% \author{\surname{Mao} Tse-Tung}\end{verbatim}
+%
+% \subsection{The abstract}
+% An abstract for a paper is specified by using the \env{abstract}
+% environment:
+% \begin{verbatim}
+% \begin{abstract}
+% Text of abstract
+% \end{abstract}\end{verbatim}
+% Note that with this package, the abstract must be specified before the
+% \cmd\maketitle\ command, and there is no need to embed it in an explicit
+% minipage environment.
+%
+% \subsection{PACS codes}
+% Some authors are asked to supply suggested PACS codes with their
+% submissions. The \cmd\pacs\ macro is provided as a way to do this:
+% \begin{verbatim}\pacs{23.23.+x, 56.65.Dy}\end{verbatim}
+% The actual display of the PACS numbers below the abstract is
+% controlled by two class options: \classoption{showpacs} and
+% \classoption{noshowpacs}. In particular, this is now independent of
+% the \classoption{preprint} option. \classoption{showpacs} must be
+% explicitly included in the class options to display the PACS codes.
+%
+% \subsection{Keywords}
+% A \cmd\keywords\ macro may also be used to indicate keywords for the
+% article.
+% \begin{verbatim}\keywords{nuclear form; yrast level}\end{verbatim}
+% This will be displayed below the abstract and PACS (if supplied). Like
+% PACS codes, the actual display of the the keywords is controlled by
+% two classoptions: \classoption{showkeys} and
+% \classoption{noshowkeys}. An explicit \classoption{showkeys} must be
+% included in the \cmd\documentclass\ line to display the keywords.
+%
+% \subsection{Institutional report numbers}
+% Institutional report numbers can be specified using the \cmd\preprint\
+% macro. These will be displayed in the upper lefthand corner of the
+% first page. Multiple \cmd\preprint\ macros may be supplied (space is
+% limited though, so only three or less may actually fit).
+%
+% \subsection{maketitle}
+% After specifying the title, authors, affiliations, abstract, PACS
+% codes, and report numbers, the final step for formatting the front
+% matter of the manuscript is to issue the \cmd\maketitle\ command:
+% \begin{verbatim}\maketitle\end{verbatim}
+% This command must follow all of the macros listed above.
+% The macro will format the front matter in accordance with the various
+% class options that were specified in the
+% \cmd\documentclass\ line (either implicitly through defaults or
+% explicitly).
+%
+%
+% \section{Compatability with \LaTeX's Required Packages}
+% Certain packages, usually ones written by members of the
+% \LaTeX\ Project itself, have been designated ``required'' and
+% are distributed as part of standard \LaTeX.
+% These packages have been placed in a priviledged position
+% vis \'a vis the \LaTeX\ kernel in that they override the definitions of certain kernel macros.
+%
+% The \classname{ltxfront} package will be incompatible with any package that
+% redefines any of the kernel macros that \classname{ltxfront} patches---if that
+% package is loaded \emph{after} \classname{ltxfront}.
+%
+% Hereinafter follows some notes on specific \LaTeX\ packages.

+% End of the preliminary portion of the package code.

+%
+% \subsection{Options}%
+% Package options are treated in this portion of the dtx file.
+% This portion is guarded by the \texttt{options} \classname{docstrip} code so that it can be
+% merged into a larger package gracefully.
+% \begin{macrocode}
+%<*options>
+% \end{macrocode}
+%
+% Package option turns on diagnostics that trace its operation.
+% \cmd\frontmatterverbose@sw\ is set false by default: we do not elect to monitor
+% the workings of these procedures.
+% \begin{macrocode}
+\DeclareOption{frontmatterverbose}{\@booleantrue\frontmatterverbose@sw}%

+%
+% Package option inactivates its syntax, for testing purposes.
+% \begin{macrocode}
+\DeclareOption{inactive}{\@booleanfalse\frontmatter@syntax@sw}%
+\@booleantrue\frontmatter@syntax@sw
+% \end{macrocode}
+%
+% \begin{macro}{\runinaddress@sw}
+% The flag \cmd\runinaddress@sw\ signifies that author addresses are to be set on the same
+% line with the author.
+%
+% The \classoption{runinaddress} option is the only one that sets \cmd\runinaddress@sw\ to true.
+%
+% FIXME: this option pertains to cases where \cmd\groupauthors@sw\ is true, but is independant of \cmd\@affils@sw.
+% So, it should be possible to assert both \classoption{runinaddress} and \classoption{unsortedaddress} as well as
+% each separately.
+% \begin{macrocode}
+\@booleanfalse\runinaddress@sw
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@affils@sw}
+% If \cmd\@affils@sw\ is false, an address is never recognised as ``new''
+% and is therefore always entered into the affiliation list,
+% stopping groups of authors at the same address being consolidated
+% into the same list:
+% the address will be printed the same number of times it is entered.
+%
+% The \classoption{unsortedaddress} option is the only one that sets \cmd\@affils@sw\ to false.
+% \begin{macrocode}
+\@booleantrue\@affils@sw
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\groupauthors@sw}
+% The flag \cmd\groupauthors@sw\ signifies that authors are to be grouped,
+% affecting the meaning of \cmd\@author@present.
+%
+% Clients will want to set \cmd\groupauthors@sw\ true if they want grouped addresses
+% or either of the following variants:
+% for unsorted addresses: set \cmd\@affils@sw\ false;
+% for run-in addresses, set \cmd\runinaddress@sw\ true.
+% \begin{macrocode}
+\@booleanfalse\groupauthors@sw
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{groupedaddress}
+% If we take the \classoption{groupedaddress} option as the default, then we can look upon
+% the \classoption{superscriptaddress} option as simply turning \cmd\groupauthors@sw\ to \cmd\false@sw.
+%
+% \classoption{groupedaddress}, the default in APS journals, groups authors above a common address.
+% \begin{macrocode}
+\DeclareOption{groupedaddress}{\clo@groupedaddress}%
+\def\clo@groupedaddress{%
+ \@booleantrue\groupauthors@sw
+ \@booleantrue\@affils@sw
+ \@booleanfalse\runinaddress@sw
+}%
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{unsortedaddress}
+% \classoption{unsortedaddress} is similar to \classoption{groupedaddress},
+% but turns off \cmd\@affils@sw,
+% with the result that each address that is entered will be printed.
+% \begin{macrocode}
+\DeclareOption{unsortedaddress}{\clo@unsortedaddress}%
+\def\clo@unsortedaddress{%
+ \@booleantrue\groupauthors@sw
+ \@booleanfalse\@affils@sw
+ \@booleanfalse\runinaddress@sw

+% \end{macro}
+%
+% \begin{macro}{runinaddress}

+%<*kernel>
+% \end{macrocode}
+%
+% This package implements a new syntax for the title page of an article.
+%
+% Special acknowledgment: this package uses concepts pioneered
+% and first realized by William Baxter (mailto:web at superscript.com)
+% in his SuperScript line of commercial typesetting tools, and
+% which are used here with his permission.
+%
+% These macros were first coded by David P. Carlisle for the American Physical
+% society in the late 1990s as part of the development of REV\TeX4.
+% That development work was taken over by Arthur Ogawa, who is the author of
+% this package.
+%
+% \subsection{Initialization}%
+%
+% \begin{macro}{\frontmatter@init}
+% The \cmd\frontmatter@init\ procedure sets up all the registers for
+% processing the title page.
+% At present, this is done once, at \cmd\class@documenthook\ time.
+% If multiple title pages are to be processed within a job,
+% the initialization must be done for each.

+% The author uses \cmd\title\ to specify the title. As in the AMS
+% classes, \cmd\title\ has an optional argument specifying a short form
+% for use in running heads.
+%
+% Once the \cmd\title\ is given, you can specify any combination of
+% \cmd\thanks, \cmd\email, \cmd\homepage, and \cmd\altaffiliation\ commands,
+% applying to the title of the document.
+%
+% Compatibility note: as with all of the standard \LaTeX\ commands that we override,
+% we make here a private definition and later switch it in if so required.

+% \subsubsection{Commands for author or collaboration}%
+%
+% \begin{macro}{\author}
+% Each author is given in a \emph{separate} \cmd\author\ command.
+% This is similar to the AMS classes, but the AMS also try to support
+% the \classname{article} class's \cmd\and\ command for putting multiple
+% authors in one \cmd\author\ command.
+% This package, however, does not support the \cmd\and\ command.
+%
+% When the \cmd\author\ command is encountered,
+% the previous author, author group, affiliation, and affiliation group are at an end.
+% This procedure moves the previous author to the author group (\cmd\move@AU),
+% moves the previous affiliation to the affiliation group (\cmd\move@AF),
+% and terminates the previous author/affiliation group (\cmd\move@AUAF) as the case may require.
+%
+% Compatibility note: as with all of the standard \LaTeX\ commands that we override,

+%
+% This procedure does exactly what \cmd\author\ does, and sets
+% a flag signifying that the \cmd\collaboration\ command was given.

+% Abstract, as in AMS classes, must be specified \emph{before}
+% \cmd\maketitle. It just saves everything up in \cmd\absbox.
+% \changes{4.0d}{1998/01/31}{If empty \cs{abstractname} omit spacing}
+% \changes{4.0d}{1998/01/31}{hookify}
+% Note that the specifics of how the abstract is to be
+% formatted are set by \cmd\frontmatter@abstractwidth,
+% \cmd\frontmatter@abstractheading, and \cmd\frontmatter@abstractfont.
+%
+% Here we wish to set the abstract into type but save it away in a box, much like
+% the \cmd\minipage\ command does.
+%
+% Note that the \cmd\endabstract\ portion of the environment
+% begins with code that mostly duplicates \cmd\endminipage, but without the \cmd\@iiiparbox.
+% At the end, we simply transfer the contents of the \cmd\minipage\
+% into a box of our own.
+%
+% However, we also have to end the gratuitous
+% paragraph begun by \cmd\minipage.
+% We ensure that no trace of that paragraph is left,
+% by absorbing the \cmd\parindent\ box.
+% Doing so destroys the paragraph entirely, except
+% for the \cmd\parskip\ glue, and that morsel is pruned, because we are at the top
+% of a page.
+%
+% This mechanism is vulnerable, however, because anything placed into the horizontal list
+% after the \cmd\parindent\ box will confound it.
+% And that is exactly what happens under Mik\TeX:
+% There seems to be an extension to the \TeX\ standard operating here which inserts a \cmd\special \ at the beginning of every paragraph.
+% (The mechnism is \emph{not} based on \cmd\everypar.)
+%
+% To accomodate this state of affairs,
+% we have a new mechanism that offers an even more complete rewrite of \env{minipage}.
+%
+% Note that an entry is made in the toc for the abstract; this has the side effect
+% of creating a PDF bookmark for this element if the \classname{hyperref} package is in effect.

+% \subsection{Syntax switch}%
+% \changes{4.1b}{2008/08/02}{Make the syntax of this package switch optional}%
+%
+% Shall we take over the syntax of \LaTeX?
+% By default, Yes, unless the Boolean below has already been defined.
+% In the package version, this is controlled by an option;
+% in the kernel version, the Boolean remains undefined.
+%
+% \cmd\maketitle\ presents a complication. If this code will execute under
+% \classname{ltxgrid}, then its version of the procedure will do fine.
+%
+% As a package, under \classname{article}, things are different.
+% In this case, what should be done depends upon \cmd\if@titlepage.
+% If true, then just execute \cmd\maketitle\ as it stands.
+% If false, then the \classname{article} class has defined its wrapper
+% procedure, and we should take over the meaning of \cmd\@maketitle\ instead.
+%
+% Here is a list of the commands defined by this package that potentially override
+% those of standard \LaTeX:
+% \cmd\frontmatter@title,
+% \cmd\frontmatter@author,
+% \cmd\frontmatter@and,
+% \cmd\frontmatter@thanks,
+% \cmd\frontmatter@date,
+% \env{frontmatter@abstract},
+% \env{frontmatter@titlepage},
+% \cmd\frontmatter@maketitle.
+%
+% The following code will perform that override, given the appropriate state of the Boolean.
+% \begin{macrocode}
+\@ifxundefined\frontmatter@syntax@sw{\@booleantrue\frontmatter@syntax@sw}{}%
+\frontmatter@syntax@sw{%
+ \let\title \frontmatter@title
+ \let\author \frontmatter@author
+ \let\date \frontmatter@date

+% \subsection{Bill of Materials}
+%
+% Following is a list of the files in this distribution arranged
+% according to provenance.
+%
+% \subsubsection{Primary Source}%
+% One single file generates all.
+%\begin{verbatim}
+%ltxgrid.dtx
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{latex ltxgrid.dtx}}%
+% Typesetting the source file under \LaTeX\
+% generates the readme and the installer.
+%\begin{verbatim}
+%README-LTXGRID ltxgrid.ins
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{tex ltxgrid.ins}}%
+% Typesetting the installer generates
+% the package files.
+%\begin{verbatim}
+%ltxgrid.sty
+%\end{verbatim}
+%
+% \subsubsection{Documentation}%
+% The following are the online documentation:
+% \begin{verbatim}
+%ltxgrid.pdf
+% \end{verbatim}
+%
+% \subsubsection{Auxiliary}%
+% The following are auxiliary files generated
+% in the course of running \LaTeX:
+% \begin{verbatim}
+%ltxgrid.aux ltxgrid.idx ltxgrid.ind ltxgrid.log ltxgrid.toc
+% \end{verbatim}
+%
+% \section{Code common to all modules}%
+%
+% The following may look a bit klootchy, but we
+% want to require only one place in this file
+% where the version number is stated,
+% and we also want to ensure that the version
+% number is embedded into every generated file.
+%
+% Now we declare that
+% these files can only be used with \LaTeXe.
+% An appropriate message is displayed if
+% a different \TeX{} format is used.
+% \begin{macrocode}
+%<*driver|package>
+\NeedsTeXFormat{LaTeX2e}[1995/12/01]%
+%</driver|package>
+% \end{macrocode}
+% As desired, the following modules all
+% take common version information:
+% \begin{macrocode}
+%<kernel&!package&!doc>\typeout{%
+%<*package|doc>
+\ProvidesFile{%
+%</package|doc>
+%<*kernel|package|doc>
+ltxgrid%
+%</kernel|package|doc>
+%<*doc>
+.dtx%
+%</doc>
+%<package>.sty%
+%<*package|doc>
+}%
+%</package|doc>
+% \end{macrocode}
+%
+% The following line contains, for once and for all,
+% the version and date information.
+% By various means, this information is reproduced
+% consistently in all generated files and in the
+% typeset documentation.
+% Give credit where due.
+% \begin{macrocode}
+%<*doc|package|kernel>
+%<version>
+ [2019/01/18/14:29:48 4.2c page grid package (portions licensed from W. E. Baxter web at superscript.com)]% \fileversion
+%</doc|package|kernel>
+%<kernel&!package&!doc>}%
+% \end{macrocode}
+%
+%
+% \section{The driver module \texttt{doc}}
+%
+% This module, consisting of the present section,
+% typesets the programmer's documentation,
+% generating the \file{.ins} installer and \file{README-LTXGRID} as required.
+%
+% Because the only uncommented-out lines of code at the beginning of
+% this file constitute the \file{doc} module itself,
+% we can simply typeset the \file{.dtx} file directly,
+% and there is thus rarely any need to
+% generate the ``doc'' {\sc docstrip} module.
+% Module delimiters are nonetheless required so that
+% this code does not find its way into the other modules.
+%
+% The \enve{document} command concludes the typesetting run.
+%
+% \begin{macrocode}
+%<*driver>
+% \end{macrocode}
+%
+% \subsection{The Preamble}
+% The programmers documentation is formatted
+% with the \classname{ltxdoc} class with local customizations,
+% and with the usual code line indexing.
+% \begin{macrocode}
+\documentclass{ltxdoc}
+\RequirePackage{ltxdocext}%

+%\fi
+\CodelineIndex\EnableCrossrefs % makeindex -s gind.ist ltxgrid
+\RecordChanges % makeindex -s gglo.ist -o ltxgrid.gls ltxgrid.glo
+% \end{macrocode}
+%
+% \subsubsection{Docstrip and info directives}
+% We use so many {\sc docstrip} modules that we set the
+% \texttt{StandardModuleDepth} counter to 1.
+% \begin{macrocode}
+\setcounter{StandardModuleDepth}{1}
+% \end{macrocode}
+% The following command retrieves the date and version information
+% from this file.
+% \begin{macrocode}
+\expandafter\GetFileInfo\expandafter{\jobname.dtx}%
+% \end{macrocode}
+%
+% \subsection{The ``Read Me'' File}
+% As promised above, here is the contents of the
+% ``Read Me'' file. That file serves a double purpose,
+% since it also constitutes the beginining of the
+% programmer's documentation. What better thing, after
+% all, to have appear at the beginning of the
+% typeset documentation?
+%
+% A good discussion of how to write a ReadMe file can be found in
+% Engst, Tonya, ``Writing a ReadMe File? Read This''
+% \emph{MacTech} October 1998, p. 58.
+%
+% Note the appearance of the
+% \cmd\StopEventually\ command, which marks the
+% dividing line between the user documentation
+% and the programmer documentation.
+%
+% The usual user will not be asked to
+% do a full build, not to speak
+% of the bootstrap.
+% Instructions for carrying these processes
+% begin the programmer's manual.

+\maketitle
+
+This file embodies the \classname{ltxgrid} package,
+the implementation and its user documentation.
+
+The distribution point for this work is
+\url{journals.aps.org/revtex},
+which contains the REV\TeX\ package, and includes source and documentation for this package.
+
+The \classname{ltxgrid} package was commissioned by the American Physical Society
+and is distributed under the terms of the \LaTeX\ Project Public License 1.3c,
+the same license under which all the portions of \LaTeX\ itself is distributed.
+Please see \url{http://ctan.tug.org/macros/latex/base/lppl.txt} for details.
+
+To use this document class, you must have a working
+\TeX\ installation equipped with \LaTeXe\
+and possibly pdftex and Adobe Acrobat Reader or equivalent.
+
+To install, retrieve the distribution,
+unpack it into a directory on the target computer,
+into a location in your filesystem where it will be found by \LaTeX;
+in a TDS-compliant installation this would be:
+\file{texmf/tex/macros/latex/revtex/.}
+
+To use, read the user documentation \file{src/ltxgrid.pdf}.
+
+\tableofcontents
+
+\section{Processing Instructions}
+
+The package file \file{ltxgrid.sty}
+is generated from this file, \file{ltxgrid.dtx},
+using the {\sc docstrip} facility of \LaTeX
+via |tex ltxgrid.dtx|.
+The typeset documentation that you are now reading is generated from
+this same file by typesetting it with \LaTeX\ or pdftex
+via |latex ltxgrid.dtx| or |pdflatex ltxgrid.dtx|.
+
+\subsection{Build Instructions}
+
+You may bootstrap this suite of files solely from \file{ltxgrid.dtx}.
+Prepare by installing \LaTeXe\ (and either tex or pdftex) on your computer,
+then carry out the following steps:
+\begin{enumerate}
+\item
+Within an otherwise empty directory,
+typeset \file{ltxgrid.dtx} with \TeX\ or pdftex;
+thereby generating the package file \file{ltxgrid.sty}.
+
+\item
+Now typeset \file{ltxgrid.dtx} with \LaTeX\ or pdflatex;
+you will obtain the typeset documentation you are now reading,
+along with the file \file{README-LTXGRID}.
+
+Note: you will have to run \LaTeX\ twice, then \file{makeindex}, then
+\LaTeX\ again in order to obtain a valid index and table of contents.
+
+\item
+Install the following files into indicated locations within your
+TDS-compliant \texttt{texmf} tree (you may need root access):
+\begin{itemize}
+\item
+\file{$TEXMF/}\file{tex/}\file{latex/}\file{revtex/}\classname{ltxgrid.sty}
+\item
+\file{$TEXMF/}\file{source/}\file{latex/}\file{revtex/}\classname{ltxgrid.dtx}
+\item
+\file{$TEXMF/}\file{doc/}\file{latex/}\file{revtex/}\classname{ltxgrid.pdf}
+\end{itemize}
+where \file{TEXMF/} stands for \file{texmf-local/}, or some other \texttt{texmf} tree in your installation.
+\item
+Run \texttt{mktexlsr} on directory \file{$TEXMF/} (you may need root access).
+\item
+Build and installation are now complete;
+now put a \cmd\usepackage\texttt{\{ltxgrid\}} in your document preamble!
+(Note: \texttt{ltxgrid} requires package \texttt{ltxutil}.)
+\end{enumerate}

+% \section{Using this package}
+% Once this package is installed on your filesystem, you can employ it in
+% adding functionality to \LaTeX\ by invoking it in your document or document class.
+%
+% \subsection{Invoking the package}
+% In your document, you can simply call it up in your preamble:
+% \begin{verbatim}
+%\documentclass{book}%
+%\usepackage{ltxgrid}%
+%\begin{document}
+%<your document here>
+%\end{document}
+% \end{verbatim}
+% However, the preferred way is to invoke this package from within your
+% customized document class:
+% \begin{verbatim}
+%\NeedsTeXFormat{LaTeX2e}[1995/12/01]%
+%\ProvidesClass{myclass}%
+%\LoadClass{book}%
+%\RequirePackage{ltxgrid}%
+%<class customization commands>
+%\endinput
+% \end{verbatim}
+%
+% Note that this package requires the features of the \classname{ltxutil} package,
+% available at
+% \url{publish.aps.org/revtex}.
+%
+% Once loaded, the package gives you acccess to certain procedures,
+% usually to be invoked by a \LaTeX\ command or environment, but not at the document level.
+%
+% \subsection{Changing the page grid}%
+% This package provides two procedures, \cmd\onecolumngrid, \cmd\twocolumngrid,
+% that change the page grid (it can be extended to more columns and to other page grids).
+%
+% They differ from standard \LaTeX's \cmd\onecolumn\ and \cmd\twocolumn\ commands in that
+% they do not force a page break. Also, upon leaving a multiple-column grid, the columns are balanced.
+% In other respects they work same.
+%
+% They differ from the grid-changing commands of Frank Mittelbach's \classname{multicol} package
+% in that they allow floats of all types (single- and double column floats, that is) and
+% preserve compatability with the \classname{longtable} package.
+%
+% These commands must be issued in vertical mode (conceivably via a \cmd\vadjust) such that
+% they are ultimately present in the MVL, where they can do their work.
+% Because they do not work in \LaTeX's left-right mode, they are unsuitable at the
+% document level.
+% Furthermore, packaging a grid command in a \cmd\vadjust, although possible, will probably
+% not acheive satisfactory page layout.
+%
+% Page grid commands are not intended to be issued unnecessarily: only the first of
+% two successive \cmd\onecolumngrid\ commands is effective; the second will be silently ignored.
+%
+% \DescribeMacro\onecolumngrid
+% You command \LaTeX\ to return to the one-column grid with the
+% \cmd\onecolumngrid\ command. If you are already in the one-column grid, this
+% is a no-op. The one-column grid is considered special of all page grids, in that
+% no portion of the page is held back (in \cmd\pagesofar); all items that might go
+% on the current page (with the exception of floats and footnotes) are on the MVL.
+%
+% \DescribeMacro\twocolumngrid
+% You command \LaTeX\ to return to the two-column grid with the
+% \cmd\twocolumngrid\ command. If you are already in the two-column grid, this
+% is a no-op.
+%
+% These two commands should be issued by a macro procedure that can ensure that
+% \TeX\ is in outer vertical mode.
+%
+% \subsection{Changing the MVL}%
+%
+% This package also provides commands to modify the main vertical list (MVL) in a safe way.
+% The scheme here is to structure, insofar possible, \TeX's MVL as follows:
+%\begin{quotation}
+%box or boxes\\
+%penalty\\
+%glue
+%\end{quotation}
+% This should be a familiar sequence. It is the prototype sequence for a vertical list,
+% and is followed when \TeX\ breaks paragraphs into lines, and when \TeX\ generates
+% a display math equation.
+%
+% If you (as a macro programmer) wish to modify the value of the penalty or glue item,
+% you can use one of the MVL-altering commands to do so. Certain operations are implemented
+% here; you can make up your own.
+%
+% Note that these commands must be issued in vertical mode, perhaps via a \cmd\vadjust\ or a \cmd\noalign.
+% They can work directly if you are in inner mode (say within a parbox or a minipage).
+%
+% \DescribeMacro\removestuff
+% You instruct \LaTeX\ to remove both the penalty and the glue item with this command.
+%
+% \DescribeMacro\addstuff
+% You issue the \cmd\addstuff\arg{penalty}\arg{glue} command to add a penalty, glue, or both.
+% If you do not wish to add one or the other, the corresponding argument should be nil.
+% Note that the effect of \cmd\addstuff\ is to stack the penalties and glue items.
+% Therefore, the lesser of the two penalties takes effect,
+% and the two glue items add together.
+%
+% \cmd\addstuff\ is limited because once applied, it cannot be applied again with correct results.
+%
+% \DescribeMacro\replacestuff
+% The \cmd\replacestuff\ command is syntactically the same as \cmd\addstuff, but works
+% differently: the existing penalty and glue are replaced or modified.
+%
+% The specified penalty is not inserted if the existing penalty is greater than 10000
+% (that is, in case of a \cmd\nobreak), otherwise, the lower (non-zero) of the two penalties is inserted.
+%
+% If the specified glue has a larger natural component than the existing glue, we replace the glue.
+% However, if the specified glue's natural component is negative, then the existing glue's natural component is
+% changed by that amount.
+%
+% \cmd\replacestuff\ can be applied mutiple times bceause it retains the list structure in the canonical form.
+%
+% Note that we treat two penalties specially (as does \TeX): a penalty of 10000 is considered
+% a garbage value, to be replaced if found. This is the signal value that \TeX\ inserts on
+% the MVL replacing the penalty that caused the page break (if the page break occurred at a penalty).
+% Also, a penalty of zero is indistinguishable from no penalty at all, so it will always
+% be replaced by the given value.
+%
+% Therefore, it is highly recommended to never set any of \TeX's penalty parameters to
+% zero (a value of, say, 1, is practically the same), nor should a skip parameter be set to zero
+% (instead, use, say, 1sp). Also, to prevent a pagebreak, do not use a penalty of 10000, use, say
+% 10001 instead.
+%
+% You can define your own construct that modifies the MVL:
+% Define a command, say, \cmd\myadjust, as follows:
+%\begin{verbatim}
+%\def\myadjust#1{\noexpand\do@main@vlist{\noexpand\@myadjust{#1}}\@tempa}%
+%\end{verbatim}
+% that is, \cmd\myadjust\ invokes \cmd\do@main@vlist, passing it the procedure name
+% \cmd\@myadjust\ along with the arguments thereof pre-expanded.
+% Next, define the procedure \cmd\@myadjust:
+%\begin{verbatim}
+%\def\@myadjust#1{<meddle with the MVL>}%
+%\end{verbatim}
+% when \cmd\@myadjust\ executes, you will be in the output routine (in inner vertical mode)
+% and the MVL will be that very vertical list.
+%
+%
+%
+%
+% \section{Compatability with \LaTeX's Required Packages}
+% Certain packages, usually ones written by members of the
+% \LaTeX\ Project itself, have been designated ``required'' and
+% are distributed as part of standard \LaTeX.
+% These packages have been placed in a priviledged position
+% vis \'a vis the \LaTeX\ kernel in that they override the definitions of certain kernel macros.
+%
+% Compatability between \classname{ltxgrid} and these packages is complicated
+% by a number of factors. First is that \classname{ltxgrid} alters the meaning of some of the same
+% kernel macros as certain of the ``required'' packages.
+% Second is that fact that certain of the ``required'' packages of \LaTeX\ are incompatible with
+% each other.
+%
+% Examples of the first kind are the \classname{ftnright}, \classname{multicol}, and \classname{longtable}
+% packages.
+% The \classname{ltxgrid} package is not compatible with \classname{multicol},
+% but if you are using \classname{ltxgrid}, you do not need to use \classname{ftnright} or \classname{multicol}
+% anyway. The \classname{ltxgrid} package does however attempt to be compatible with \classname{longtable}.
+%
+% Among the ``required'' packages that are mutually incompatible are \classname{multicol} and \classname{longtable},
+% the incompatibility arising because both packages replace \LaTeX's output routine:
+% if one package is active, the other must not be so.
+% This state of affairs has remained essentially unchanged since the introduction of the two as \LaTeX2.09 packages in the late 1980s.
+%
+% The reason that \classname{ltxgrid} can remain compatible with \classname{longtable} is due to the
+% introduction of a more modern architecture, the ``output routine dispatcher'', which allows all macro packages access to the
+% safe processing environment of the output routine, on an equal footing.
+% The relevant portions of the \classname{longtable} package are reimplemented in \classname{ltxgrid}
+% to take advantage of this mechanism.
+%
+% Timing is critical:
+% the \classname{ltxgrid} package will be incompatible with any package that
+% redefines any of the kernel macros that \classname{ltxgrid} patches---if that
+% package is loaded \emph{after} \classname{ltxgrid}.
+%
+% Hereinafter follows some notes on specific \LaTeX\ packages.
+%
+% \subsection{ftnright}
+% Frank Mittelbach's \classname{ftnright} package effects a change to \LaTeX's
+% \cmd\twocolumn\ mode such that footnotes are set at the bottom of the right-hand
+% column instead of at the foot of each of the two columns.
+%
+% Note that it overwrites three \LaTeX\ kernel macros: \cmd\@outputdblcol, \cmd\@startcolumn, and \cmd\@makecolumn.
+% Fortunately none of the three are patched by \classname{ltxgrid}, so that compatability
+% is not excluded on this basis.
+%
+% At the same time, it changes the meaning of \cmd\footnotesize, the macro that is automatically
+% invoked when setting a document's footnote into type.
+% One might well argue that it is an error for the meaning of \cmd\footnotesize\ to be determined by
+% a package such as \classname{ftnright}, that indeed such a choice should be made in the
+% document class, or in a file such as \file{bk10.clo}.
+%
+% To avoid being tripped up by this misfeature in \classname{ftnright}, it is only necessary to
+% reassert our meaning for \cmd\footnotesize\ later on, after \classname{ftnright} has been loaded.
+%
+% Note that \classname{ftnright} inserts code that demands that \LaTeX's flag \cmd\if@twocolumn\
+% is true, that is, it will complain if deployed in a \cmd\onecolumn\ document.
+% It is therefore necessary for any other multicolumn package to assert that flag in order to
+% avoid this package's complaint. It is an interesting question exactly why this package has
+% this limitation. After all, a one-column page grid is just a degenerate case of the
+% two column.
+%
+% \subsection{longtable}
+% David Carlisle's \classname{longtable} package sets tables that can be so long as to break over pages.
+% According to its author, it uses the same override of \LaTeX's output routine as
+% Frank Mittelbach's \classname{multicol} package. By implication, then, it has a hard
+% incompatability with the latter.
+%
+% The \classname{longtable} package also performs a check of whether the document is in
+% \cmd\twocolumn\ mode, and declines to work if this is the case. It is not clear, however,
+% that there is any true incompatability present if so. It's just that David did not see any reason
+% anyone would want to set such long tables in a multicolumn document, hence the check.
+%
+% There does not appear to be any indication that \classname{longtable} would work less
+% well under \classname{ltxgrid} than under standard \LaTeX's \cmd\twocolumn\ mode.
+% Therefore, this \classname{ltxgrid} patches \classname{longtable} (if loaded) so as to provide
+% compatability. In the course of which, \classname{longtable} becomes more robust
+% (\classname{longtable} has mumerous bugs and incompatabilities of long standing,
+% some of which are repaired by \classname{ltxgrid}).
+%
+% One problem remains, namely that, if a \env{longtable} environment breaks over columns
+% and thereby inserts its special headers and footers at that break, and those columms are then
+% balanced (due to a return to the one-column page grid), then those inserted rows
+% will remain, and may no longer fall at the column break. This will, of course look
+% wrong.
+%
+% The only way to fix this problem is to avoid doing column balancing in the way
+% I have implemented here; such an enhancement to this package is possible.
+%
+% \subsection{multicol}
+% Frank Mittelbach's \classname{multicol} package provides a page grid with many columns,
+% albeit denies the placement of floats in individual columns.
+%
+% It establishes its own \cmd\output\ routine, which is the reason it runs afoul of
+% the \classname{longtable} package. On the other hand, \classname{ltxgrid} specifically
+% allows for the case where a package installs its own \cmd\output\ routine, so
+% there is no incompatability on that basis.
+%
+% Still, it is pointless to use \classname{multicol} if you are using \classname{ltxgrid},
+% since both packages provide multicolumn page layouts.
+% Therefore, \classname{multicol} is not supported by \classname{ltxgrid}.
+%
+% \subsection{ltxgrid}
+% It has been pointed out that one of the disadvantages of adopting the \classname{ltxgrid} package is that
+% it does alter the \LaTeX\ kernel.
+% Any package that itself alters the \LaTeX\ kernel may be incompatible with \classname{ltxgrid}, and new packages
+% (destined perhaps to become part of the successor to \LaTeXe) may break \classname{ltxgrid}.
+%
+% The consequence is that packages introduced in future, and future changes to \LaTeX\ may be incompatible
+% with \classname{ltxgrid}.
+% This is, of course, true.
+% The development plan for \classname{ltxgrid} is that when such packages and \LaTeX\ kernel changes come about,
+% the burden will be on \classname{ltxgrid} to change in a way that provides for continued compatability with
+% those packages and \LaTeX\ kernel changes.
+%
+%
+% \section{How \classname{ltxgrid} places footnotes}
+%
+% In conventional multicolumn layouts, a footnote will appear at the bottom of the column in which it is called out.
+% The \classname{ltxgrid} package implements this conventional layout choice by default.
+% However, other choices are possible (a la \classname{ftnright}, whose compatability with \classname{ltxgrid} has not been tested).
+%
+% One unusual feature of \classname{ltxgrid}'s default implementation must be mentioned, though,
+% namely the case in a two-column page grid, where a footnote is followed by a temporary change to the one-column page grid
+% (e.g., for a wide equation).
+% In such a case, the material above the wide material is split into two columns, and a footnote whose callout
+% appears in the right-hand column will nonetheless be set at the base of the left column.
+%
+% This arrangement was chosen because it ensures that the footnotes at the bottom of any page will appear in
+% numerical order. It can be argued that this choice is ``incorrect'', but be that as it may,
+% the \classname{ltxgrid} package does not foreclose on other arrangements for the footnotes.
+% The package can be adapted to accomodate any page design desired.
+%
+% \section{Limitations in \classname{ltxgrid}'s default column balancing method}%
+%
+% In a multicolumn page grid, when encountering a page that is not completely full,
+% it is customary to set the material in balanced columns (typically with the last column no longer than any of the others).
+% Such a case also crops up when temporarily interrupting the multicolumn grid to set material on the full width of the page:
+% the material on the page above the break is customarily set in balanced columns.
+%
+% An awkward case arises when we have already set one or more complete columns of type before encountering the need to
+% balance columns. In this subset of cases, the default in \classname{ltxgrid} is to
+% do an operation I call ``re-balancing'':
+% the material on the page so far is pasted back together into a single column, and new, balanced column breaks are
+% calculated.
+%
+% This scheme typically works fine, but it has a significant vulnerability:
+% any discardable items trimmed at the original column break are lost, never to be retrieved.
+% Consequently, after re-balancing, an element like, say, a section head can fail to have the correct amount of whitespace above.
+%
+% This problem is due to an unfortunate optimization in \TeX, wherein a certain class of nodes is trimmed from the
+% top of main vertical list upon returning from the output routine:
+% any penalty, glue, or leader node falls in to this class of discardable nodes,
+% and trimming proceeds until a non-discardable node (such as a box, or rule) is encountered.
+% It gets better: a third class of nodes is transparent to this trimming process;
+% they are neither discarded nor do they halt the process of trimming:
+% mark nodes and all whatsits fall into this class of transparent nodes;
+% they are quietly passed over during trimming.
+%
+% An alternative approach for \TeX\ to take would have been,
+% rather than discarding the node entirely, to simply \emph{mark} it as discarded.
+% (Implementors of extended \TeX, please note!)
+% Then, upon shipping out, such nodes would not make it into the DVI.
+% \TeX's optimization, driven by the small computer architectures current when it was developed,
+% does save mem, but at the cost of revisiting page breaks in a reliable way.
+%
+% FIXME: how to fix a column break in the above case? Widetext?

+% \section{Implementation of package}
+%
+% Special acknowledgment: this package uses concepts pioneered
+% and first realized by William Baxter (mailto:web at superscript.com)
+% in his SuperScript line of commercial typesetting tools, and
+% which are used here with his permission. His thorough understanding
+% of \TeX's output routine underpins the entire \classname{ltxgrid}
+% package.

+% The command \cmd\linefoot\ sets a single, automatically numbered line, but with a footnote (with the specified label);
+% it automatically increments the line counter.
+% These commands are typically used to construct test documents.
+%
+% Because the counter is globally advanced and never reset, successive
+% calls to \cmd\lineloop\ should have an argument ever larger.
+% The formatted output will have each line labeled with its ordinal number.

+%
+%
+% \subsection{Mark Components}%
+%
+% Override LaTeX's mark macros to allow more components.
+%
+% We remain bound by the weakness of LaTeX's scheme in that
+% one cannot emulate the action of \TeX\ whereby
+% material with marks can be inserted in the middle of
+% a vertical list such that the marks are reliably calculated.
+% If we did that, \cmd\@themark\ would no longer be utilized.
+%
+% A more robust scheme involves placing all marks (component and value)
+% into a list (using global scoping, i.e., \cmd\gdef),
+% and using \cmd\@@mark to place an index on that list into the MVL.
+% Then, e.g., \cmd\@@botmark signifies the place where that list is to be cut,
+% and the \cmd\botmark\ of any component is
+% the value of the last element of the cut
+% list having the given component. The \cmd\firstmark\ and \cmd\topmark\
+% can likewise be defined relative to \cmd\@@firstmark\ and \cmd\@@topmark,
+% except in the latter case, we want the first following the cut instead of the last
+% preceding the cut.
+%
+% The limitation of this scheme is its demands upon \TeX's mem.
+% The list of marks would need to be trimmed back to, effectively,
+% \cmd\topmark\ at the beginning of every page.
+%
+% This approach is not yet part of the extended LaTeX kernel.
+%

+%
+% \subsubsection{Procedures that expose the component data structure}%
+% This portion of the code exposes the internal representation of
+% the mark components. If we wish to add more components, we will have to revise
+% these macro definitions:
+% \cmd\@themark,
+% \cmd\nul@mark,
+% \cmd\set@mark@netw@,
+% \cmd\set@marktw@,
+% \cmd\set@markthr@@,
+% \cmd\get@mark@@ne,
+% \cmd\get@mark@tw@,
+% \cmd\get@mark@thr@@,
+% \cmd\get@mark@f@ur.
+%
+% \begin{macro}{\@themark}
+%FIXME: is it safer to eliminate \cmd\@themark\ in favor of a message that evaluates \cmd\@@botmark?
+%
+% Note: these definitions expose the data structure of mark components.
+% \begin{macrocode}

+\def\nul@mark{{}{}{}{}\@@nul}%
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\set@mark@netw@}

+% These procedures insert the new value of a particular mark component into the given argument.
+% They expose the data structure of mark components.

+% \subsubsection{Procedures that do not expose the component data structure}%
+%
+% \begin{macro}{\mark@netw@}
+% \begin{macro}{\marktw@}
+% \begin{macro}{\markthr@@}
+% These procedures insert the new value of a particular mark component into \cmd\@themark,

+% \subsection{Output Super-routine}%
+%
+% We want to change \LaTeX's output routine, but do not wish to remain vulnerable
+% to interference from such ``required'' packages as
+% \classname{multicol} (authored by Frank Mittelbach)
+% and \classname{longtable} (authored by David P. Carlisle), which
+% swap in their own output routines when the respective package is active.
+%
+% The better mechanism, used here, is due to William Baxter (web at superscript.com),
+% who has allowed his several ideas to be used in this package.
+%
+% In what follows, we effectively wrap up the old \LaTeX\ output routine inside
+% a new, more flexible ``super routine''. When the output routine is called,
+% the ``super routine'' acts as a dispatcher. If the old routine is needed, it is called.
+%
+% If a package attempts to substitute in their own output routine, they will effectively
+% be modifying a token register by the name of \cmd\output.
+% The primitive \cmd\output\ is now known by a different name, which should no longer be
+% necessary to use.
+%
+% Usage note: to make a visit to the output routine employing the dispatcher, enter
+% with a value of \cmd\outputpenalty\ that corresponds to a macro. Defining as follows:
+%\begin{verbatim}
+%\@namedef{output@10000}{<your code here>}%
+%\end{verbatim}
+% by convention, your output routine should void out \cmd\box\cmd\@cclv.
+%
+% In rewriting \LaTeX's output dispatcher
+% in a much simpler form, we also avoid the sin of multiple \cmd\shipout s
+% within a single visit to the output routine.
+%
+% Conceptually, we divide visits to the output routine into two classes.
+% The first involves natural page breaks
+% (at a \cmd\newpage\ or when \cmd\pagetotal $>$ \cmd\pagegoal)
+% and usually resulting in \cmd\box\cmd\@cclv\ either being shipped out or
+% salted away (e.g., each column in a multicolumn layout).
+% We might call this class the ``natural output routines''; the \cmd\outputpenalty\
+% will never be less than $-10000$.
+% Furthermore, we ensure that \cmd\holdinginserts\ is cleared when
+% calling such routines.
+%
+% The other class involves a forced visit to the output routine
+% via a large negative penalty ($< -10000$). They do not generally
+% result in a \cmd\shipout\ of \cmd\box\cmd\@cclv: they may be dead cycles.
+% We provide a mechanism (call it a ``one-off'' output routine) that allows
+% us to specify certain processing to be done when \TeX\ reaches
+% the current position on the page.
+%
+% One-off output routines themselves fall into two divisions, ones
+% that process \cmd\box\cmd\@cclv, and ones that work on the main vertical list (MVL).
+% The former are typified by changes to the page grid, perhaps
+% even column balancing.
+% The latter involve the insertion of penalties or glue and the processing of floats.
+%
+% The natural output routine is a single procedure. We have not introduced multiple
+% natural output routines based on the \cmd\outputpenalty\ because \TeX\ does not
+% support such a thing: \TeX\ sometimes lays down a penalty whose value is the sum
+% of other penalties. Because of this, we cannot depend on the value of \cmd\outputpenalty\
+% in such areas.
+%
+% We do introduce flexibility in the form of a mechanism for patching into the
+% natural output routine. Three hooks are offered, allowing a procedure
+% to prepare for the upcoming visit to the output routine,
+% access to \cmd\box\cmd\@cclv, and after doing \cmd\shipout\ (or otherwise
+% committing the material to the page).
+%
+% Environments, commands, and even packages can install their
+% own procedures into these hooks.
+% For instance, if the longtable package is loaded, it will install
+% its procedures, but those procedures will punt if the page break
+% being processed does not actually fall within a longtable environment.
+%
+% \begin{macro}{\primitive@output}
+% Here we remember the \TeX\ primitive \cmd\output\ and its value,
+% and then proceed to take over the \cmd\csname\ of \cmd\output,
+% making it a \cmd\toks\ register and installing the old value of
+% the output routine.
+% \begin{macrocode}
+\let\primitive@output\output
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\output@latex}
+% \begin{macro}{\output}
+% Grab the tokens in \cmd\the\cmd\output\ (but without the extra set of braces).
+% The value of \cmd\toks@\ must remain untouched until loaded into the appropriate token
+% register; this is done a few lines below.

+%
+% A comment on compatibility with other packages that co-opt the output routine.
+%
+% Somewhere on the LaTeX-L list, David Kastrup has urged macro writers to take over
+% the output routine in such a way that others can do likewise. How is this to be
+% accomplished?
+%
+% Consider what the \classname{lineno} package does when it loads.
+% \begin{enumerate}
+% \item
+% It does \cmd\let\ cmd\@tempa\ \cmd\output.
+% This has the effect of identifying \cmd\@tempa\ with the
+% \cmd\toks\ register we created above to hold the old output routine of \LaTeX.
+% Let us say that was \cmd\toks14.
+% \item
+% \classname{lineno} itself effectively does \cmd\newtoks\ \cmd\@LN@output,
+% which assigns that \cmd\csname\ to \cmd\toks 15.
+% \item
+% It loads \cmd\@LN@output\ with the contents of \cmd\@tempa
+% (that is, \cmd\toks14, our copy of \LaTeX's output routine).
+% \item
+% Then it loads \cmd\@tempa\ with its own desired procedure,
+% to be executed at \cmd\output\ time, thereby taking over what it thinks is the output routine,
+% but which is in reality the procedure \revtex\ executes when it wants to pass control
+% to \LaTeX's original output routine.
+% \item
+% It then does \cmd\let\ \cmd\output\ \cmd\@LN@output,
+% which now identifies \cmd\output\ with \cmd\toks15, the output routine of \classname{lineno}.
+% \item
+% When the \cmd\output\ routine is triggered,
+% the primitive output routine \cmd\primitive@output\ is executed, and if
+% appropriate, control is passed to \cmd\output@latex, which \revtex\ had loaded with the old
+% \LaTeX\ output routine, but which is presently loaded with that of \classname{lineno}.
+% \item
+% The output routine of \classname{lineno} is executed, and if appropriate control is passed
+% to \cmd\@LN@output, the old output routine of \LaTeX.
+% \item
+% Furthermore, the \cmd\csname\ \cmd\output\ now points to \cmd\@LN@output\ (\cmd\toks15).
+% This means that someone coming in after \classname{lineno} to take over the output routine
+% will actually get executed after that of \classname{lineno}, but before \LaTeX.
+% \end{enumerate}
+% As you can see, the process of taking over the output routine may continue until all of the
+% \cmd\toks\ registers have been allocated.
+% If, say, \classname{newpackage} would itself like to take over the output routine,
+% and if it uses the above set of steps, then when the output routine is triggered, the order
+% of execution is \revtex, then \classname{lineno}, then \classname{newpackage}, then \LaTeX.
+% Each new package inserts itself on front of \LaTeX.

+%
+% \subsection{Further thoughts about inserts}
+%
+% The only safe way to deal with inserts is to either set \cmd\holdininserts\ or
+% to commit to using whatever insert comes your way: you cannot change your mind
+% once you see a non-void \cmd\box\cmd\footins, say.
+%
+% Therefore all output routine processing must proceed with \cmd\holdinginserts\ set
+% until you are sure of the material to be committed to the page. At that point, you
+% can clear \cmd\holdinginserts, spew \cmd\box\cmd\@cclv, put down the appropriate penalty,
+% and exit, with the knowledge that \TeX\ will re-find the same pagebreak, this time
+% visiting the output routine with everything, including inserts, in their proper
+% place.
+% This technique applies to split elements (screens, longtable, index) as well as to
+% manufactured pages (float pages and clearpage pages).
+%
+% Therefore, the output routine must not make assumptions about whether \cmd\holdinginserts\
+% should be cleared; instead this must be left to the one-off output routines or the natural output routine.
+%
+% If we are manufacturing pages (``float page processing''), and if \cmd\pagegoal\ is not equal to
+% \cmd\vsize, then inserts are at hand, and our criterion should take into account the insert
+% material, even though we cannot measure its height based on the size of \cmd\box\cmd\footins\
+% (because \cmd\holdinginserts\ is set, you see).
+%
+% It would be better to take the complement of \cmd\floatpagefraction\ and use that
+% as a standard for the looseness of the page. Since \cmd\pagegoal\ reflects the inserted material,
+% the criterion becomes the difference of the aggregate height of the floats and the \cmd\pagegoal\
+% versus this "page looseness" standard.
+%
+% As a check, consider what happens if we bail out: \cmd\@deferlist\ has never been touched, so it
+% requires no attention. Also, \cmd\holdinginserts\ has never been cleared, so inserts require
+% no attention. So we only have to ensure that marks are preserved, which is already taken
+% care of by the message handler mechanism.
+%
+% If we are doing ordinary page cutting, then the scheme would be to detect whether we are within
+% a screen (or longtable as may be), do the adjustment to the page height, and return, but this time
+% with \cmd\holdinginserts\ cleared. Upon reentering the output routine, we may or may not be within
+% the screen environment, but we are now sure to have a final page break, and we can commit this
+% material (by shipping out or by saving it out as a full column).
+%
+% In the above, the first of the two visits to the output routine is a dead cycle and requires
+% propagation of marks, but nothing else.
+%
+% \subsection{The difference between inserts and floats}
+%
+% While revisiting this package in 2008, I needed to clarify under what circumstances inserts
+% would be added to the \cmd\pagesofar. My conclusion is that I had been treating them
+% exactly the same as floats, but that was a mistake.
+%
+% Floats can be committed at the top of a column, in the middle, or at the bottom.
+% Footnotes (the only \cmd\insert\ that is used in \LaTeX) may only be committed at the bottom
+% of a column. So, it was necessary to provide two versions of \cmd\@combinepage, one
+% that committed \cmd\insert s, and the other that did not, the former used only when
+% a column of text was committed. Note that even after a column is committed, we could change our minds:
+% for instance if in multicolumn grid and we decide to balance the columns.
+%
+%
+% \subsection{The natural output routine}
+%
+% Here is the portion of the output routine that fields cases not handled by
+% the dispatcher.
+%
+% The default is to ship out a page and then look around for more material
+% that might constitute a ``float page''. However, because \cmd\holdinginserts\
+% is normally set, this output routine must first have a dead cycle and
+% come back again with \cmd\holdinginserts\ cleared.
+% Then, after shipping out, it puts down a message that
+% will manufacture zero or more float pages, finally terminating
+% with a procedure that commits floats to a new unfinished page.
+%
+% To accomodate special processing, we execute hooks whose name is based
+% on the value of the "envir" mark component. The default is "document",
+% ensured by an initial mark of that value; the associated procedures
+% are all nil. Any unknown envir value will "\cmd\relax\ out".
+%
+% The test made by \cmd\toggle@insert\ tells whether we are on our first visit to
+% the output routine (with \cmd\holdinginserts\ still positive), or our second
+% (with \cmd\holdinginserts\ zeroed). The output routine will toggle the setting.
+%
+% The commands \cmd\hold@insertions\ and \cmd\move@insertions\ respectively
+% clear and set \cmd\holdinginserts, so this procedure effectively
+% clears \cmd\holdinginserts\ just long enough to pick up the insertions.
+% Important: any output routine that clears \cmd\holdinginserts\
+% must guarentee that it is restored on the subsequent visit to the output routine.
+% Or, to put it another way, if an output routine detects that \cmd\holdinginserts\
+% is cleared, it should take it upon itself to restore it to a positive value before exiting.
+%
+% The branch with \cmd\holdinginserts\ set is executed first; the other
+% branch follows on practically immediately thereafter. In the first branch,
+% we simply execute the appropriate hook and then execute a dead cycle.
+%
+% In the branch with \cmd\holdinginserts\ cleared, the procedure
+% builds up the current column, which is now complete, with \cmd\@makecolumn, then
+% dispatches to the shipout routine associated with the current page grid, \cmd\output@column@.
+% At the end, it triggers the execution of an output routine to prepare the next column (or page).
+%
+% \subsection{Natural output routine}%
+%
+% \begin{macro}{\natural@output}
+% \begin{macro}{\output}
+% Here is the output routine that handles natural pagebreaks:
+% we now have page that needs to be shipped out or a portion of a page that is ready to be committed to the page grid.
+% Processing is of necessity divided into phases, \cmd\output@holding\ is executed upon first encountering the natural page-breaking point, while inserts are being held.
+% The second phase, \cmd\output@moving, is set in motion by the first: here the same material (in most cases) will be processed with \cmd\holdinginserts\ cleared,
+% and the insertions (e.g., footnotes) are split off into their assigned box registers.
+% \begin{macrocode}
+\def\natural@output{\toggle@insert{\output@holding}{\output@moving}}%
+\output@latex{\natural@output}%
+% \end{macrocode}
+%
+% In accordance with the scheme suggested by David Kastrup for allowing another output routine
+% to slip itself into ours, we use a token register called \cmd\output.
+% However, we reserve the ability to restore things if we so desire.
+% This we must do in the case of the \filename{lineno.sty} package, because its functionality
+% is best served by being integrated into our own dispatcher-based output routine.
+%
+% To restore our own output routine, we can repeat the above assignment,
+% \begin{verbatim}
+%\output@latex{\natural@output}%
+% \end{verbatim}
+% some time before the document begins.
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\output@holding}
+% \begin{macro}{\@if@exceed@pagegoal}
+% The procedure \cmd\output@holding\
+% is our first cycle through the output routine; \cmd\holdinginserts\ is still set.
+% We give the current environment a heads up
+% (it is through this means that \classname{longtable} sets its running header and footer),
+% then we execute a dead cycle, which should propagate marks.
+%
+% One corner case that can crop up is the presence of a single unbreakable chunk whose size is larger
+% than \cmd\vsize.
+% Doing a dead cycle under such circumstances will not find the same breakpoint as this time
+% (remember we threw in a \cmd\mark\ node).
+% Instead, we attempt to remove the excess height of the material, so we can continue to propagate marks.
+%
+% The corner case is at hand if the natural size of \cmd\box\cmd\@cclv\ exceeds \cmd\pagegoal\ and
+% the contents cannot be shrunk to fit.

+% \begin{macro}{\dead@cycle}
+% \begin{macro}{\dead@cycle@repair}
+% The procedure \cmd\dead@cycle\ is defined separately as a utility which can be used by
+% any output processing routine to emulate what takes place in the standard output routine.
+%
+% Here, we have entered the output routine with \cmd\holdinginserts\ enabled, which means that we
+% are not yet ready to ship out material, because the \cmd\insert\ registers are being held.
+% We want to clear \cmd\holdinginserts\ and come back here with the same page break as before, whereupon
+% we may properly proceed with page makeup.
+%
+% To do this, we
+% propagate marks, then spew the contents of \cmd\box\cmd\@cclv\ followed by the
+% original output penalty that landed us here (but only if it is not 10000,
+% the flag value for a pagebreak not at a penalty).
+%
+% However, the natural output routine should do this only if \cmd\box\cmd\@cclv\ is nontrivial.
+% A pathological case exists wherein a box of height greater than \cmd\textheight\ would cause an infinite loop involving the output routine.
+% The procedure \cmd\dead@cycle@repair, attempts to catch this case and avoid the loop.
+%
+% The test of the height of \cmd\box\cmd\@cclv\ is not the correct one, because this test will run afoul in
+% the case where \cmd\box\cmd\@cclv\ contains nothing but an \cmd\insert\ node. What to do?
+%
+% It is possible that the pathological case can be detected by looking at \cmd\pagetotal. If that quantity is
+% zero, then \cmd\box\cmd\@cclv\ really is trivial.
+%
+% In the procedure \cmd\dead@cycle@repair, if \cmd\box\cmd\@cclv\ is nontrivial, we execute \cmd\dead@cycle,
+% otherwise it contains nothing but a mark, so we dispense with propagating marks
+% and we simply spew out \cmd\box\cmd\@cclv\ without an accompanying mark.
+% This has the effect of failing to propagate marks, but this problem is preferrable to the infinite loop,
+% which in principle could crash even a robust operating system by filling up the file system.
+%
+% If a document has such a large chunk, it should be fixed, so we give a message in the log.
+%
+% You ask, ``In what way does this infinite loop come about?'' Good question!
+%
+% The setup is a chunk in the MVL that is taller than \cmd\textheight.
+% (Yes, it's that simple.)
+% As soon as the previous page ships out, the MVL will contain a mark (propagated from the previous page) followed
+% by that large chunk (call it the `big bad box', albeit does not need to be a single box).
+% The next visit to the output routine will be a natural page break, but
+% \TeX\ will select the juncture between the mark and the big bad box as the least-cost page break.
+% Unless the test in \cmd\dead@cycle\ is done, the cycle is perpetuated when the macro
+% reinserts the mark.
+%
+% The crux matter is achieving, in a robust way, the goal of going from a \cmd\holdinginserts\ state to one
+% where the insertions are moving.

+% The procedure \cmd\do@startcolumn@pen\ is executed as a one-off output routine

+%
+% Its job is to either generate a ``float page'' (in reality a column) for shipping out,
+% or to commit deferred floats to the fresh column, concluding with a dead cycle.
+% In the former case, we accomodate split footnotes and other insertions (by comparing \cmd\vsize\ and \cmd\pagegoal):
+% the floats are spewed onto the page, whereupon \LaTeX's output routine will place the footnotes and ship out,
+% iterating the process once again.
+%
+% Note that when this procedure is invoked, \cmd\box\cmd\@cclv\ still has within it the protection box, so we
+% start by removing it. Note also that if there was a split insertion held over from the previous page, the
+% insert node will be present in \cmd\box\cmd\@cclv, \emph{prior to} the protection box. For this reason, we cannot
+% just throw away that box, as we might be tempted to do.
+%
+% FIXME: where else do we possibly inappropriately discard \cmd\box\cmd\@cclv?
+%
+% Note that, because a column or page page had previously just been completed,

+%
+% A Note on terminology:
+% In a single-column page grid, you might expect that we would execute the procedure \cmd\do@startpage.
+% But this is not so.
+% \LaTeX\ has a confustion of long standing,
+% in which the procedures that handle full-page width floats in a two-column page grid all have in their names

+% Note that this procedure will inevitably be followed by \cmd\do@startcolumn.

+%
+% If no float page is formed, we attempt to commit full-page-width floats to the text page, and return with a dead cycle.
+% We are now ready to compose columns of text.
+%
+% Note that all floats (both column floats and full-page-width floats) move through a single queue.
+% To differentiate between the two, the width of the float is compared to \cmd\textwidth.

+% Whenever a page is shipped out, \LaTeX\ automatically tries out a float column:
+% a page containing nothing but floats (and, as we have added here, split footnotes).
+%
+% The following four procedures employ certain macros to communicate between each other:
+%
+% \cmd\fcolmade@sw, a boolean, says whether we were successful in making a float column.
+%
+% \cmd\if@test, a \cmd\newif\ switch, says a float has failed some test.
+%
+% \cmd\@deferlist, is the input to the process, a list, of deferred floats.
+%
+% \cmd\@trylist, a list, stores the deferred floats to be tried out on the float column.
+%
+% \cmd\@failedlist, a list of floats that have failed the selection for the float column.
+%
+% \cmd\@flfail, a list of floats that have failed the second selection for the float column.
+%
+% \cmd\@flsucceed, a list, the floats that have been successfully placed on the float column.
+%
+% \cmd\@freelist, a list, receives any freed floats.
+%
+% \cmd\@colht, a dimen, the available space for the column, including column floats and insertions (footnotes).
+%
+% \cmd\@fpmin, a dimen, the required minimum height for the float column.
+%
+% \cmd\@outputbox, a box, the output of the process.
+%
+% \cmd\@fptop, \cmd\@fpsep, \cmd\@fpbot, glue, placed above, between, and below floats on the float column.
+%
+% \cmd\@currtype, a count, used temporarily for the float's bits.
+%
+% \cmd\@tempcnta, a count, used temporarily for the float's bits.
+%
+% In \cmd\@tryfcolumn, we alter the criterion for a float page, because if footnotes are present at this point
+% (presumably due to a split insertion) then \cmd\@fpmin is no longer the right threshold to apply.
+%
+% Note that we have changed \cmd\@tryfcolumn, \cmd\@xtryfc, and \cmd\@ztryfc\ syntactically so that the procedure
+% to test for the float's being a column float versus a full-page-width float is passed in as an

+% \subsection{Clearing pages}%
+%
+% Clearing the page is an elaboration of ending the page: it entails flushing all floats.
+%
+% This package might make number of float flushing algorithms available,
+% a very simple one that does not try to produce excellent pages,
+% another that tries to make the best use of space,
+% and a more complex one that tries to balance columns.
+%
+% At the beginning of the page-clearing process, by definition all of the paragraph text involved is on the MVL and all floats have been encountered.
+% There may be material in \cmd\pagesofar, and (in a multi-column page grid) any number of columns of the page have been composed.
+% Also, there might be footnote material saved up in \cmd\footsofar.
+%
+% Because we did not want to perform multiple \cmd\shipout s per visit to the output routine,
+% our multi-column page makeup will not compose multiple columns per visit.
+% This implementation detail may not require alteration, but it is not a limitation that is truly necessary:
+% it is only multiple \cmd\shipout s per visit that must be avoided.
+%
+% The crux matter is how to continue with flushing floats even after the material in the MVL is exhausted.
+% At that point, we must, upon completion of the output routine,
+% insert into the MVL an interrupt that triggers the next step in the processing.
+%
+% Therefore, after processing a \cmd\do@startcolumn\ interrupt, we must somehow force the completion of that column.
+% This could be done by inserting a \cmd\do@newpage@pen\ interrupt.
+%
+% And after processing a \cmd\do@startpage@pen\ interrupt, that results in \cmd\@dbltopinsert s,
+% we must ensure that the multiple columns on the page get completed, so that the page itself finally gets shipped out.
+% This part will proceed automatically given that \cmd\do@startcolumn\ processing completes successfully.
+%
+% The process will not be complete until all deferred floats have been placed and shipped out, and all saved-up footnotes have been inserted.
+%
+% Full-page-width floats can get out of order of column floats. This problem can be remedied by holding them all in the same list.
+% We therefore stop using \cmd\@dbldeferlist\ entirely, and all of the procedures that formerly used it have been rewritten to
+% use \cmd\@deferlist\ instead. When traversing the list, we apply a selector on the given box that determines whether it is a column-width or page-width float.
+% This selector is different depending on the page grid.
+%
+% When the \cmd\@deferlist\ is processed (by any means), we have to take care of the case where a float of one category is passed over but we are looking for a float of the other category.
+% Here, we must terminate processing, to avoid disordering the floats. This we do by the usual means.
+%
+% The system has a Boolean that says we are clearing pages: \cmd\clearpage@sw; if it is true,
+% then at the tail of \cmd\do@startcolumn\ processing, we should put down a (\cmd\vfil?) \cmd\do@newpage@pen\ interrupt.
+% This is because the MVL is now empty, so we have to force the columns to complete.
+%
+% One potential very pathological case would be where there is one or more deferred floats that never successfully get placed:
+% placing floats has stalled, and we will ship out blank pages indefinitely. How to detect this case?
+%
+% First, \cmd\do@startpage\ will evidently be stalled if the following are all true:
+% a) \cmd\@tryfcolumn\ and \cmd\@sdblcolelt\ both fail,
+% b) there are deferred floats available for page placement, and
+% c) the \cmd\@colht=\cmd\textheight, that is, the full page height is available for placement of column floats.
+%
+% Second, \cmd\do@startcolumn\ will evidently be stalled if the following are all true:
+% a) tryfcolumn fails,
+% b) there are deferred floats available for column placement, and
+% a) the \cmd\@colroom=\cmd\textheight, that is, the full page height is available for placement of column floats.
+%
+%
+% \begin{macro}{\cleardoublepage}
+% \begin{macro}{\clearpage}
+% \begin{macro}{\newpage}
+% \begin{macro}{\newpage@prep}
+% The function of \cmd\clearpage\ is to end the current page with \cmd\newpage\ and then
+% ship out additional pages until (\footins) inserts and (deferred) floats are exhausted.
+%
+% The method involves setting the float placement parameters to completely permissive values
+% and kicking out the current page (using a non-discardable penalty).
+% A possibly short page will be shipped out, followed
+% by any number of float pages. However these float pages, because using permissive float placement,
+% will exhaust all inserts and deferred floats.
+%
+% Bug Note: in the code for \cmd\clearpage, the first penalty we output is an unprotected \cmd\pagebreak@pen.
+% I tried using a protected \cmd\do@newpage@pen, but that gave rise to a corner case where a blank page
+% was output.
+%
+% At present, the \cmd\clearpage\ procedure does the same as \cmd\newpage,
+% except that \cmd\clearpage@sw\ is turned on,
+% and the (discardable) \cmd\newpage\ is inevitably followed by the same procedures
+% that are executed if a page is shipped out.
+%
+% FIXME: it seems that better than \cmd\pagebreak@pen\ would be an unprotected penalty of a special value that would
+% entail output routine processing consisting of the following steps:
+% 3) \cmd\unvbox\cmd\@cclv,
+% 1) set \cmd\clearpage@sw\ to \cmd\true@sw,
+% 2) put down a protected \cmd\do@startcolumn@pen,
+% 4) take a dead cycle.
+%
+% The effect would be to liberalize float placement options for the current column as well as further columns that may be output as part of \cmd\clearpage\ processing.
+% Of course, it would still be necessary to set \cmd\clearpage@sw\ again via an interrupt.
+%
+% An optimization might be to clear \cmd\clearpage@sw\ as part of the same interrupt,
+% but that would actually not work properly, because it is necessary for \cmd\do@endpage\ to
+% possibly invoke further visits to the output routine before clearpage processing ceases.

+% accurate. However, with \cmd\firstmark\ we must potentially examine each contribution
+% because the first mark on the page may happen to fall in the last piece of material contributed.
+%
+% To begin, we define the procedure that initializes the macros to appropriate flag values.
+% \begin{macrocode}
+\def\clr@top@firstmark{%

+% save away \cmd\box\cmd\@cclv, and we will never see its marks again (unless it is unboxed into the MVL),
+% because \TeX\ lets one access a box's marks only within an output routine that has put that box into \cmd\box\cmd\@cclv.

+% \LaTeX\ kernel procedures \cmd\end@float\ and \cmd\end@dblfloat\
+% have been changed to work alike; in particular, floats of both classes
+% are deferred into the same queue.
+% This measure ensures that they will be placed in their original order,
+% an aspect in which \LaTeX\ is broken.
+%
+% Note: when retrieving floats from the queues, we can differentiate those of the two categories
+% by the width of the box.
+%
+% Floats are processed via an output routine message, and are checked for
+% sanity in re the float placement options. In the case of full-page-width floats,
+% we ensure that the h and b float placement options are never asserted, because they
+% make no sense.
+%
+% Note that if we get to the end of the float box and still have pending
+% footnotes, we put then out.
+%
+% LaTeX Bug note: if a user types \cmd\begin{table*}[h], the float will never succeed in being placed!
+% we try to catch such cases.
+%
+% Note that the macro \cmd\check@currbox@count\ tries to catch cases where the float placement options
+% are such that the float can never be placed.
+%
+% The calls to \cmd\@iffpsbit\ are part of a procedure to deny certain of the float placement
+% parameters: ``h'' and ``b'' are not possible, the former because the \cmd\marginpar\ mechanism
+% cannot place a full-page-width float within a multicolumn page grid, the latter because nobody
+% has yet written the code to do so (pretty bad reason, I know).

+%
+% \subsection{Output messages}
+%
+% Message handlers are procedures that execute output messages, tokens that are passed to
+% the output routine for execution in an environment appropriate to page makeup.
+%
+% How it works. We put down three large negative penalties, each of which will be handled by
+% the output dispatcher (\emph{not} the natural output routine), each penalty being protected by
+% a removable, non-discardable item (i.e., a box).
+% Either three or four invocations of one-off output routines are involved per message.
+%
+% We make the last of the three protection boxes have a depth equal to the value of \cmd\prevdepth\
+% that was current when the procedure is called. This effectively restores \cmd\prevdepth.
+%
+% In each case, the one-off output routine will remove the extraneous box we have inserted.
+% And the second and third one-off routines will simply void \cmd\box\cmd\@cclv, because its contents
+% are entirely artificial.
+%
+% FIXME: not so! If \cmd\holdinginserts\ is cleared, that box may have an insert node; it must be preserved, too.
+%
+% The first routine saves away the current column contents and remembers the \cmd\topmark\ for later
+% use. There is a variant routine that first clears \cmd\holdinginserts, so that the message can
+% handle any inserts present in the boxed-up page; this of course entails yet another
+% visit to the output routine.
+%
+% The penultimate routine saves away the tokens transmitted in via the \cmd\@@mark: the argument of
+% the macro. These tokens are of course the very thing we wish to execute within the safety
+% of the output routine. It also puts down a mark containing the \cmd\topmark\ tokens saved
+% by the first routine. By this means, the mark, which we have clobbered, is restored.
+%
+% The last routine simply executes the given tokens.
+% In the course of doing this, it must take care of \cmd\box\cmd\@cclv, either by shipping it out,
+% or by \cmd\unvbox ing it onto the MVL.
+%
+% \begin{macro}{\execute@message}

+% The procedure \cmd\execute@message@insert\ is like \cmd\execute@message\ in all respects
+% except that the penalty value is \cmd\save@column@insert@pen, which arranges for the
+% message handler involved to deal with the page's insertions.
+% At the same time, we prepare the \cmd\footins\ box so that these insertions can be dealt with.
+%
+% Note:
+% If more insertions are added to \LaTeX\ (presumably via \cmd\newinsert), then they
+% must be dealt with in a way entirely analogous to \cmd\footins.

+% \subsection{Messages to alter the page grid}%
+%
+% Here is the implementation of the grid-switching procedures.
+% We perform two checks when changing the page grid; first to ensure that
+% the target page grid is known (defensive programming), second to ensure that
+% the switch is a non-trivial one. The latter check must be performed within
+% the safety of the output routine, so requires using an output message.
+% Thus, a grid change requires two messages, for a total of six visits to the output routine.
+%
+% \begin{macro}{\do@columngrid}
+% Utility procedure \cmd\do@columngrid\ changes the page grid.
+% Note that this command forces an end to the current paragraph. This is necessary, because
+% a page grid change makes no sense unless we can alter the \cmd\hsize\ before commencing to
+% typeset the following paragraph. So the command should never be executed in horizontal mode
+% anyway.
+% \begin{macrocode}

+%
+% \begin{macro}{\start@column}
+% Procedure \cmd\start@column\ lays down the interrupts to switch the page grid.
+% If the change to the page grid would have been trivial, it bails out.
+% It seems a reasonable tradeoff of processing versus security: once we commit
+% to changing the page grid, we clear \cmd\holdinginserts, so there is no turning back.
+%
+% Note that the second argument to the macro allows us to pass an argument to the
+% page grid that is starting up. This can be handy, because a single procedure can
+% handle multiple page grids, differing only by the value of a parameter.
+%
+% FIXME: this means that you cannot switch between mlt page grids in a single step.

+%
+% \subsection{Application Note: implementing a page grid}
+%
+% If you want to create a new page grid for \LaTeX,
+% you must define five procedures with specific names:
+% \cmd\open@column@ name, \cmd\shut@column@ name, \cmd\end@column@ name,
+% \cmd\output@column@ name, and \cmd\@addmarginpar@ name, where ``name'' is the
+% name of your page grid.
+%
+% The procedure \cmd\open@column@ name starts the new page grid. It should define \cmd\thepagegrid,
+% deal with \cmd\box\cmd\pagesofar\ and \cmd\box\cmd\footsofar\ (perhaps by leaving them alone),
+% and it should set the values of \LaTeX's page layout parameters for the column size and height.
+%
+% The procedure \cmd\shut@column@ name should expect to be called with \cmd\holdinginserts\
+% cleared (it can assume that \cmd\holdinginserts\ will automatically be restored).
+% It should properly deal with insertions (like footnotes); calling \cmd\@makecolumn\
+% with an argument of \cmd\false@sw\ will do this.
+% It should know that the page grid is being terminated
+% in the middle of a page, so it should make arrangements to carry the footnotes down to the
+% bottom of the column or page, and it should possibly salt away the material for later
+% incorporation into the page. The box registers \cmd\footsofar\ and \cmd\pagesofar\ are customarily used
+% for this purpose.
+%
+% The procedure \cmd\end@column@ name should kick out a possibly short page containing all the
+% floats committed to the page. It will be invoked during \cmd\clearpage\ processing.
+% After that, it should \cmd\unvbox\cmd\@cclv.
+%
+% The procedure \cmd\output@column@ name should ship out or commit the current \cmd\@outputbox.
+% In a one-column layout, you ship out; in a multicolumn layout, you commit the box as the contents
+% of a particular column, and if that column is the last, you ship out.
+%
+% The procedure \cmd\@addmarginpar@ name should return a boolean (either \cmd\true@sw\ or \cmd\false@sw\ or an equivalent)
+% to tell the marginpar mechanism to place the marginal material to the right or left, respectively.
+%
+% You can use the existing page grids ``one'' and ``mlt'' as a point of departure for creating others.
+% The former can be the basis for, say, a single-column page grid with a side column.
+%
+% \begin{macro}{\pagesofar}
+% \begin{macro}{\footsofar}

+% Note that \cmd\box@column\ makes an attempt to prevent excessive \cmd\topskip\

+% from being applied by \TeX\ when \cmd\@outputbox\ is contributed to the MVL.
+% If this is not done, it is possible to get into an infinite loop in the corner case,

+% already sufficient to fill the page.
+%
+% Note (AO 0920): I have changed the dimension involved with \cmd\box@column\ from
+% \cmd\vsize\ to \cmd\textheight, because the former is certainly not the correct value
+% to use: it will change if floats have been placed in the last column of the page.
+% I believe \cmd\textheight\ is the correct parameter to use here.
+%
+% A REVTeX4 user, Sergey Strelkov (strelkov@maik.rssi.ru), wants the option
+% of ragged-bottom columns. Implementing this feature properly means reboxing the
+% columns to their natural height only if \cmd\raggedcolumn@sw\ is true.
+% Otherwise, they get reboxed to their common height (\cmd\@colht?).
+%
+% Note that the default has hereby changed from ragged to flush.
+% It's not clear that anyone but Sergey will notice.
+%
+% The macro \cmd\marry@skip\ addresses (in a limited way)
+% the fact that neither the value of \cmd\baselineskip\ nor that of \cmd\topskip\
+% can be relied upon for the purpose of marrying the baselines of two split columns.
+% (Because there might have been a local change to their values at the point where
+% the output routine got triggered.)
+%
+% For best results, your document class should call for grid changes only when in basal text
+% settings. The \cmd\marry@baselines\ procedure will use the values appropriate to that point
+% when attempting to put the columns back together.
+%
+% In any case, we are not attempting to solve the more general problem of how to marry baselines
+% where the leading can change arbitrarily within the galley or where glue could have been trimmed
+% at a page top.

+% The story of \cmd\textheight, \cmd\@colht, \cmd\@colroom, and \cmd\vsize.
+%
+% \cmd\textheight---height of the text column. Not a running parameter, however, each time a page is
+% shipped out, the \cmd\textheight\ could in principle be altered. This must be done before
+%
+% \cmd\@colht---\cmd\textheight\ minus the height of any full-page-width floats. The latter are committed
+% only just after shipping out, and only if we are in a multicolumn page grid.
+% Therefore, \cmd\@colht\ should be set after a \cmd\shipout\ (by \cmd\@outputpage) and
+% will be adjusted when full-page-width floats are committed to the fresh page by \cmd\do@startpage.
+%
+% \cmd\@colroom---\cmd\@colht\ (adjusted by \cmd\pagesofar) minus the height of any column-width floats.
+% The latter are committed anywhere on the page, at which point \cmd\@colroom\ must be adjusted.
+% Therefore, \cmd\@colroom\ should be set (by \cmd\set@colroom) whenever a column is prepared (by ).
+%FIXME: committed (by \cmd\output@column@) and
+% will be adjusted (by \cmd\@add@float\ or \cmd\do@startcolumn) whenever a float is committted to the column.
+%
+% \cmd\vsize---\cmd\@colroom.
+% Therefore, \cmd\vsize\ should be set (by \cmd\set@vsize) whenever
+% the \cmd\@colroom\ is set (by \cmd\set@colroom) or adjusted (by \cmd\@add@float\ or \cmd\do@startcolumn)
+%FIXME: or when the \cmd\pagesofar\ box is changed (after invoking \cmd\open@column@).
+%
+% Question: what if there are committed floats? Footnotes?
+% Answer: full-page-width floats are only committed at top, and they are already reckoned with in \cmd\@colht.
+% Column-width committed floats are incorporated by \cmd\@makecolumn.
+%
+% As to footnotes, our scheme is to keep the \cmd\footins\ insert register up to date, and to use the insert mechanism
+% to ensure room for footnotes.
+% When a change is made to the page grid, the footnotes will need to be propagated back into the MVL.
+%
+% Note: FIXME: adjusting for \cmd\pagesofar\ is done at not quite the right time. I need to reexamine \cmd\set@colht,
+% because \cmd\@dbltoplist\ and \cmd\pagesofar\ really should be on the same footing.
+% Perhaps \cmd\@colht\ and \cmd\@colroom\ should both deal with their respective ``lists'' in the same way?
+%
+% These concerns will be particularly germane if we ever extend this package to deal with full-page-width floats
+% placed at the bottom of the page, or committed on the same page as called out.
+%
+% It occurs to me that we should ditch \cmd\set@colroom\ and only ever execute \cmd\set@colht,
+% which sets \cmd\@colroom\ as a side effect.
+% If so, we can make \cmd\@colht\ take \cmd\pagesofar\ into account, as it should. Then \cmd\@colht\ will return to its
+% original significance as the value that \cmd\@colroom\ is set to after a column is committed.
+%
+% On the other hand, why not simply forget all this caching and (re-)calculate \cmd\vsize\ as late as possible?
+% Particularly, \cmd\@colht\ is an artifact of the old way of doing things, where once it was set, it would never change.

+% \begin{macro}{\balance@two}
+% The procedure \cmd\balance@two\ takes two columns and balances them; in the process it removes
+% any footnotes that may be present to a place of safety \cmd\footsofar,
+% for later placement at the foot of the shipped-out page.
+% The box register \cmd\box\cmd\@ne\ is the aggregate of all columns.
+% The box register \cmd\box\cmd \z@\ is the last column.
+% The box register \cmd\box\cmd\tw@\ is the first column.
+% The \cmd\dimen\ register \cmd\dimen@\ is the trial value to \cmd\vsplit\ to,
+% initially half the height of \cmd\box\cmd\@ne.
+% The \cmd\dimen\ register \cmd\dimen@i\ is the increment for the next trial;
+% its initial value is equal to the initial value of \cmd\dimen@.
+% The \cmd\dimen\ register \cmd\dimen@ii\ is the difference of the heights of the two columns.
+%
+% The procedure uses a binary search for that value of \cmd\dimen@\ which is stable to within .5\cmd\p@\ and which
+% makes the last column be shorter than the others.
+%
+% This procedure can be extended to multiple columns simply by changing it to execute \cmd\vsplit\ multiple
+% times (one less than the total number of columns in the page layout) and to calculating \cmd\dimen@ii\
+% to be the difference of the heights of last column and the \cmd\dimen@.
+% Upon termination of the search, one would excute the \cmd\vsplit s once again, this time
+% using the actual \cmd\col@\ box registers to store the
+% balanced columns, thereby clobbering their former contents.
+%
+% Bug Note:
+% as originally written, this macro had a bug, which is well worth avoiding under similar circumstances anywhere.
+% So, learn from the mistakes of others, as they say.
+% In trying to remove the depth of the boxes created via \cmd\vsplit\ within the \cmd\loopwhile\ control,
+% I originally coded
+% \cmd\unvbox
+% \cmd\z@\
+% \cmd\setbox
+% \cmd\z@
+% \cmd\lastbox\
+% \cmd\dimen@
+% \cmd\dp
+% \cmd\z@\
+% \cmd\box
+% \cmd\z@\
+% \cmd\vskip-%
+% \cmd\dimen@.
+% The error here is that the (horizontal) shift of the last box in the vertical list will be lost in the process.
+% Simply put, \cmd\setbox\cmd\z@\cmd\lastbox\ fails to retain the shift of the box node in the vertical list,
+% and when it is put down again via \cmd\box\cmd\z@, it will no longer have the correct shift.
+%
+% This bug affected things placed in the MVL with \cmd\moveleft, \cmd\moveright, \cmd\parshape, and
+% \cmd\hangindent, as well as things shifted by \TeX's primitive mechanisms.
+%
+% A superior strategy for removing the depth of the last line of the list is more expensive, but safer:
+% make a separate copy of the list, measure the depth of the last box as above, but then discard
+% the list, retaining only the value of the dimension.
+%
+% Note that this procedure will not work if the material within is excessively chunky.
+% A particular failure mode exists where none of the material is allocated to the last (right) column.
+% We detect this case and revert to unbalanced columns.
+%
+% Another failure mode is where a large chunk occurs at the beginning of the composite box.
+% In this case, the left column may fill up even when \cmd\dimen@\ is very small.
+% If this configuration leaves the left column longer than the right, then we are done,
+% but \cmd\dimen@\ by no means represents the height of either finished box.
+%
+% Therefore the last step in the process is to rebox the two columns to a common height determined
+% independently of the balancing process.
+%
+% The dimension involved is checked against the current \cmd\@colroom\ to guard against the case where
+% excessive material happens to fall in either column.

+% which is part of /latex/required/tools, is incmpatible with both
+% \LaTeX's ``required'' package \classname{multicol} and with
+% \LaTeX's native \cmd\twocolumn\ capability. There is no essential reason
+% for this incompatability, aside from implementation details, and the
+% \classname{ltxgrid} package gives us the ability to lift them.
+%
+% Only four of \classname{longtable}'s procedures require rewriting:
+% \cmd\longtable,
+% \cmd\endlongtable,
+% \cmd\LT@start, and
+% \cmd\LT@end@hd@ft.
+% The procedure \cmd\switch@longtable\ checks against their expected meanings
+% and, if all is as expected, applies the patches.
+% In the process, we simplify things considerably and also make them more
+% secure.
+%
+% Why does \classname{longtable} need to access the output routine, anyway?
+% What it comes down to, is what happens when a pagebreak falls within a
+% long table. If this happens, we would like to append a row at the bottom of
+% the broken table and add a row at the top of the next page.
+%
+% These things can be accomodated easily by the \classname{ltxgrid} output
+% routine hooks.

+%
+% \subsection{Dealing with stuck floats and stalled float dequeueing}%
+%
+% \LaTeX's float placement mechanism is fundamentally flawed, as evidenced by
+% its warning message ``too many unprocessed floats'', which users understandably find frustrating.
+% The \classname{ltxgrid} package provides tools for ameliorating the situation somewhat.
+%
+% Two cases require detection and rectification:
+% \begin{enumerate}
+% \item
+% A float is ``stuck'' in the \cmd\@deferlist: for whatever reason, the float fails to be committed,
+% even at the start of a fresh page.
+% Once this condition prevails, following floats can never be committed, subsequently all of \LaTeX's
+% float registers are used up.
+%
+% If this condition is detected, we reconsider float dequeueing under permissive (\cmd\clearpage-style) processing.
+%
+% \item
+% The \cmd\@freelist\ is exhausted:
+% a large concentration of floats, say, uses up all of \LaTeX's float registers all at once.
+% This condition commonly occurs when the user collects floats at the end of the document, for some reason.
+%
+% When a float is encountered, \LaTeX\ uses a float register (allocated from a pool of free registers) to contain it until it can be placed.
+% However, no further action is taken until the pagebuilder is visited, so floats can accumulate.
+% Also, even after the pagebuilder is visited, deferred floats can accumulate, and these are not committed
+% until a column (or page) of text is completed.
+%
+% Once the last free float register is used, action should be taken that will commit some of the deferred floats,
+% even if this might require ending the page right where we are (resulting in a short page).
+%
+% Perhaps, committed floats should be stored using some mechanism other than a list, as is currently done.
+% A feasible alternative storage method would be to use a \cmd\box\ register in place of
+% \cmd\@toplist,
+% \cmd\@botlist, and
+% \cmd\@dbltoplist.
+% This is probably just fine, since such committed floats are not reconsidered (I think).
+%
+% \end{enumerate}
+%
+% The emergency processing implemented here immediately ends the current page and begins to output float pages under (\cmd\clearpage-style) rules.
+% It proceeds until all deferred floats have been flushed.
+%
+% Users should expect non-optimal page makeup under these circumstances.
+%
+% Note that there is a weakness in our approach that we have not attempted to repair: if floats are being
+% added as part of a paragraph, we will not be able to take these remedial steps until the paragraph ends.
+% This means that the approach implemented here cannot fix all \LaTeX\ documents. Users can still construct
+% documents that exhaust \LaTeX's pool of float registers!
+%
+% \begin{macro}{\check@deferlist@stuck}
+% \begin{macro}{\@outputpage@tail}
+% \changes{4.1b}{2008/08/04}{Procedure \cs{@outputpage@tail} tailpatches \cs{@outputpage}}%
+% We detect the case where, at the start of a fresh page, there are deferred floats, but none are
+% committed. We memorize the \cmd\@deferlist\ at \cmd\shipout\ time, then examine it at the point where
+% our efforts to commit floats to the new page are complete.
+% If it has not changed, the first float must be stuck, and we
+% attempt to fix things via \cmd\force@deferlist@stuck.
+%
+% This simple approach is comp[letely effective in for typical documents.
+%
+% Note that we try to avoid an infinite loop by examining the value of \cmd\clearpage@sw:
+% if we come here with that boolean true, we are in a loop.

+% \begin{macro}{\do@forcecolumn}
+% The procedure \cmd\force@deferlist@empty\ is an attempt to rectify a situation where \LaTeX's float placement mechanism

+%
+% We put down interrupts that call for the float placement to be redone, but under permissive conditions,
+% just the same as if \cmd\clearpage\ had been invoked.
+%
+% Note that the attempt to rectify the error is contingent on the setting of \cmd\force@deferlist@sw,
+% default false. A document class using this package that wishes to enable this error recovery mechanism should
+% set this boolean to true.
+%
+% The interrupt \cmd\do@forcecolumn@pen, which invokes the procedure \cmd\do@forcecolumn,
+% does the same as \cmd\do@startcolumn, except under permissive conditions:
+% we are trying to empty out the float registers completely.
+%
+% In order to properly with the case where there is material in \cmd\box\cmd\@cclv,
+% \cmd\@toplist, \cmd\@botlist, \cmd\@dbltoplist, etc,
+% we do what amounts to \cmd\newpage\ to get things rolling.

+%
+% A more thorough revision of \LaTeX's float placement mechanism would involve substituting a single \cmd\box\
+% register for the \cmd\@deferlist. This way, \LaTeX's ability to have latent floats would be limited by
+% box memory alone.
+%
+% Because only the \cmd\box\ and \cmd\count\ components of the float box register are actually used by \LaTeX,
+% our scheme can be accomplished if we can find a way to encode the information held in the \cmd\count\ component.

+% A first-in, first-out mechanism exists, wherein a box-penalty pair is dequeued by \cmd\lastbox\cmd\lastpenalty\cmd\unpenalty\ and enqueued
+% by \cmd\setbox\cmd\foo=\cmd\hbox\cmd\bgroup\cmd\penalty\cmd\floatpenalty\cmd\box\cmd\floatbox\cmd\unhbox\cmd\foo\cmd\egroup.
+%
+% Note that this scheme is made possible by our change to \LaTeX's float placement mechanism,
+% wherein we consolidated the two \cmd\@deferlist s into one.
+%
+% \section{Support for legacy \LaTeX\ commands}
+%
+% We provide support for the \cmd\enlargethispage\ command.
+%
+% Note: using a command of this sort does not automatically enlarge both pages of a spread, which would be the convention in page composition.
+%
+% Timing Note: In a multicolumn page grid, the user should issue the \cmd\enlargethispage\ command
+% while the first column of the page is being typeset.
+% We provide a helpful message if the timing is wrong.
+%
+% This code can serve as a model for introducing commands that need to execute within the safety of the output routine.
+% We ensure that the arguments are fully expanded, then execute \cmd\do@output@MVL\ to cause an output procedure,
+% \cmd\@@enlargethispage, to execute. When it does execute, the MVL will be exposed.
+%
+% The \cmd\@@enlargethispage\ procedure simply adjusts the vertical dimensions of the page.
+% The adjustment will persist until the column is committed, at which point the page dimension
+% will revert to its standard value.

+% \section{Line-wise processing}%
+% Sometimes we wish to process each line of type that will be placed into the galley,
+% for example, applying line numbering to a document.
+% To accomplish the task, we have to force a visit to the output routine after each such line, whereupon
+% we can process it accordingly (in the case of line numbering, we could do as \filename{lineno.sty} and
+% append an appropriately formed box to the MVL).
+%
+% In implementing such a scheme, we will have to instantiate interrupts for the following cases:
+% \begin{description}
+%
+% \item[\cmd\interlinepenalty\ and friends] These include \cmd\clubpenalty, \cmd\widowpenalty, \cmd\displaywidowpenalty, and \cmd\brokenpenalty.
+%
+%
+% \item[Display math penalties] Includes \cmd\predisplaypenalty, \cmd\postdisplaypenalty, and \cmd\interdisplaylinepenalty.
+%
+%
+% \item[\cs{par}] The penalty following the last line of the paragraph.
+%
+%
+% \item[\cmd\vadjust] A trap for any \cmd\vadjust\ command that falls in the paragraph.
+%
+% \end{description}
+%
+% \begin{macro}{\def@next@handler}
+% \begin{macro}{\def@line@handler}
+% Utility procedures \cmd\def@next@handler\ and \cmd\def@line@handler\ help in the creation of
+% interrupt handlers.
+%
+% \cmd\def@next@handler\ increments the scratch count register (argument 1),
+% using this value to \cmd\mathchardef\ its second argument
+% as the negative of the flag value to be used as a penalty for exciting the interrupt (argument 3).
+% As a byproduct, it leaves the given scratch counter incremented.
+% \begin{macrocode}

+% We wish to prevent \filename{lineno.sty} from patching \cmd\vspace\ and \cmd\pagebreak,

+%
+% We also wish to prevent that package from patching \cmd\@arrayparboxrestore, because
+% it prevents us from \cmd\unvbox ing vertical mode material into the MVL and numbering those
+% lines.
+%
+% We start by retaining the original definitions of these commands, so we can restore them

+%
+% Next, we provide for line-wise processing by patching the procedures associated with these same three commands.
+%
+% There are exactly four core \LaTeX\ procedures that use \cmd\vadjust\ to insert vertical mode material
+% into the main vertical list: \cmd\vspace, \cmd\pagebreak, \cmd\nopagebreak, and \cmd\\.
+% Other commands may use \cmd\vadjust, but they are inserting an interrupt (via a penalty${}<10000$),
+% and such a thing does not mask the depth of \cmd\box\cmd\@cclv, hence is permissible.
+%
+% In each case, we replace the core \LaTeX\ procedure with one that itself replaces \cmd\vadjust\ with
+% \cmd\ex@vadjust@ltx. The meaning of this procedure can be left as \cmd\vadjust, or it can be changed to
+% one that accomplishes the equivalent without masking the depth of \cmd\box\cmd\@cclv.
+%
+% The first procedure is \cmd\@vspace, here shown in original form and in the patched alternative form.
+% This procedure and \cmd\@vspacer\ implement the \cmd\vspace\ command.
+% \begin{macrocode}
+\def\@vspace@org #1{%

+% \end{macrocode}
+%
+% The procedure \cmd\@no@pgbk\ implements both \cmd\pagebreak\ and \cmd\nopagebreak.
+% \begin{macrocode}

+%
+% The command to end a line of type, \cmd\\, is defined via \cmd\DeclareRobustCommand,
+% so we must proceed carefully:
+% A procedure is defined whose \cmd\long\cmd\csname\ is contructed via the incantation:
+% \cmd\csname\cmd\expandafter\cmd\@gobble\cmd\string\cmd\\ \cmd\endcsname.
+% Note the non-trivial space character after the \cmd\\: it is incorporated into
+% the \cmd\csname.
+%
+% Here is the original core \LaTeX\ definition for

+% to force a visit to the output routine, where the line of type is given its number.
+% In order to properly measure the depth of \cmd\box\cmd\@cclv, it defers \cmd\vadjust\
+% commands that may insert \cmd\vskip\ or \cmd\penalty\ nodes.
+%
+% The implementation of that package, however, manipulates \cmd\holdinginserts\ in a dangerous
+% way: outside the safety of the output routine. It also alters the meaning of \cmd\vadjust\
+% using global assignments. We patch its code to avoid these problems. The \filename{ltxgrid}
+% package already has the needed mechanisms in place to do these jobs correctly.
+%
+% The methods we use can accomodate any values of penalties like \cmd\clubpenalty, etc:
+% we do not make assumptions about the range of values these penalty parameters could take.

+% We patch them to avoid doing this: in ltxgrid-based classes like REVTeX, the output routine properly manages \cmd\holdinginserts, so packages should not attempt to do so.
+% Also, we will want \cmd\linenumberpar\ to set \cmd\interlinepenaly\ to dispatch to \cmd\MakeLineNo.

+% We have just begun a display math, and any paragraph we are setting will now end.

+% we will replace the penalty with its normal value.

+% We provide a handler for the last line of a paragraph.

+\def\handle@par@LN{%
+ \Make@LineNo@ltx
+% \end{macrocode}
+% After setting the line number, we arrange for an appropriate penalty to
+% be laid down after this visit to the output routine ends.

+% Query: why not contribute the penalty right here in the visit to the output routine?
+% \begin{macrocode}
+ \@tempcnta\lastpenalty
+ \@ifnum{\@tempcnta=\z@}{}{%
+ \expandafter\gdef
+ \expandafter\@LN@parpgbrk
+ \expandafter{%
+ \expandafter\penalty
+ \the\@tempcnta
+% \end{macrocode}
+% When \cmd\@LN@parpgbrk\ is executed, it resets itself to the default value,
+% \cmd\@LN@screenoff@pen.
+%
+% Query: \cmd\@LN@screenoff@pen\ appears to try to restore the depth of the last box:
+% why is this being done outside the safety of the output routine?
+% \begin{macrocode}
+ \global\let\@LN@parpgbrk\@LN@screenoff@pen
+ }%
+ }%
+}%
+% \end{macrocode}
+%
+% \begin{macro}{\Make@LineNo}
+% The procedure \cmd\Make@LineNo\ sets the box containing the line number itself.
+% \begin{macrocode}
+\def\Make@LineNo@ltx{%
+ \@LN@maybe@normalLineNumber
+% \end{macrocode}
+% We measure the depth of \cmd\box\cmd\@cclv\ and unbox it.
+% At this point, it is crucial that that box have the same depth as that of the last
+% box within it.
+%
+% In the simple case, \cmd\box\cmd\@cclv\ is
+% a \cmd\vbox\ containing as its last box the \cmd\hbox\ of the paragraph we are processing.
+%
+% Query: under what circumstances will this \emph{not} be the case?
+% \begin{macrocode}
+ \boxmaxdepth\maxdimen\setbox\z@\vbox{\unvbox\@cclv}%
+ \@tempdima\dp\z@
+ \unvbox\z@
+% \end{macrocode}
+% Then we create the box with the line number, setting its height to zero.
+% \begin{macrocode}
+ \sbox\@tempboxa{\hb@xt@\z@{\makeLineNumber}}%
+ \ht\@tempboxa\z@
+% \end{macrocode}
+% With these preparations, we invoke \cmd\@LN@depthbox, which
+% lays that box down (with its depth appropriately set):
+% this procedure depends on our having set \cmd\@tempdima\ and \cmd\@tempboxa
+% (kinda kludgy way of passing arguments, really).
+% \begin{macrocode}
+ \@LN@depthbox
+% \end{macrocode}
+% Now increment the line number. I have relocated this token past \cmd\@LN@depthbox:
+% this may induce a bug, but I am going to hereby force the issue:
+% why split up the procedure that lays down boxes with a procedure that sets a register value?
+% \begin{macrocode}
+ \stepLineNumber
+% \end{macrocode}
+% Finally, execute the \cmd\vadjust s that fell within the line that we just handled.
+%
+% Note that \cmd\enqueue@vadjust@ltx\ had queued up all the \cmd\vadjust\ commands for the paragraph
+% into \cmd\g@vadjust@queue, laying down an (\cmd\int@vadjustpenalty) interrupt in each ones' place.
+% The interrupts associated with this line of the paragraph have now moved the tokens to \cmd\g@vadjust@line,
+% which we now expand and execute.
+% \begin{macrocode}
+ \g@vadjust@line
+ \global\let\g@vadjust@line\@empty
+}%
+% \end{macrocode}
+%
+% \begin{macrocode}
+\def\write@linelabel#1{%
+ \protected@write\@auxout{}{%
+ \string\newlabel{#1}{{\theLineNumber}{\thepage}{}{}{}}%
+ }%
+}%
+% \end{macrocode}
+%
+% \begin{macrocode}
+\def\ex@vadjust@line{%
+ \@if@sw\ifLineNumbers\fi{\enqueue@vadjust@ltx}{\vadjust}%
+}%
+% \end{macrocode}
+% \end{macro}
+%
+% Note that the \cmd\linelabel\ commands use a mechanism different from \cmd\vadjust,
+% embodied in the procedure \cmd\enqueue@vadjust@ltx, wherein the
+% \cmd\write\ primitives are enqueued while the paragraph is being processed, each replaced with
+% an interrupt, then dequeued and executed by the interrupt handler, leaving a \cmd\write\ node
+% in place of the interrupt (just where the \cmd\vadjust 's vertical mode material would had been)
+% just below the box containing the line of type. This \cmd\write, like all whatsits,
+% does not affect the depth of \cmd\box\cmd\@cclv, unlike the case of general vertical mode material,
+% which could have interfered.

+% \subsubsection{Primary Source}%
+% One single file generates all.
+%\begin{verbatim}
+%ltxutil.dtx
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{latex ltxutil.dtx}}%
+% Typesetting the source file under pdflatex
+% generates the readme and the documentation.
+%\begin{verbatim}

+%
+% \subsubsection{Generated by \texttt{tex ltxutil.dtx}}%
+% Typesetting this file with \TeX\ generates
+% the package file.
+%\begin{verbatim}
+%ltxutil.sty
+%\end{verbatim}
+%
+% \subsubsection{Auxiliary}%
+% The following are auxiliary files generated
+% in the course of running \LaTeX:
+% \begin{verbatim}
+%ltxutil.aux ltxutil.idx ltxutil.ind ltxutil.log ltxutil.toc
+% \end{verbatim}
+%
+% \section{Code common to all modules}%
+%
+% We want to require only one place in this file
+% where the version number is stated,
+% and we also want to ensure that the version
+% number is embedded into every generated file.
+%
+% Now we declare that
+% these files can only be used with \LaTeXe.
+% An appropriate message is displayed if
+% a different \TeX{} format is used.
+% \begin{macrocode}

+%
+%
+% \section{The driver module \texttt{doc}}
+%
+% This module, consisting of the present section,
+% typesets the programmer's documentation,
+% generating the \file{README-LTXUTIL} as required.
+%
+% Because the only uncommented-out lines of code at the beginning of
+% this file constitute the \file{doc} module itself,
+% we can simply typeset the \file{.dtx} file directly,
+% and there is thus rarely any need to
+% generate the ``doc'' {\sc docstrip} module.
+% Module delimiters are nonetheless required so that
+% this code does not find its way into the other modules.
+%
+% The \enve{document} command concludes the typesetting run.
+%
+% \begin{macrocode}
+%<*doc>
+% \end{macrocode}
+%
+% \subsection{The Preamble}
+% The programmers documentation is formatted
+% with the \classname{ltxdoc} class with local customizations,
+% and with the usual code line indexing.
+% \begin{macrocode}
+\documentclass{ltxdoc}
+\RequirePackage{ltxdocext}%
+\let\url\undefined

+%\fi
+\CodelineIndex\EnableCrossrefs % makeindex -s gind.ist ltxutil
+\RecordChanges % makeindex -s gglo.ist -o ltxutil.gls ltxutil.glo
+% \end{macrocode}
+%
+% \subsubsection{Docstrip and info directives}
+% We use so many {\sc docstrip} modules that we set the
+% \texttt{StandardModuleDepth} counter to 1.
+% \begin{macrocode}
+\setcounter{StandardModuleDepth}{1}
+% \end{macrocode}
+% The following command retrieves the date and version information
+% from this file.
+% \begin{macrocode}
+\expandafter\GetFileInfo\expandafter{\jobname.dtx}%
+% \end{macrocode}
+%
+% \subsection{The ``Read Me'' File}
+% As promised above, here is the contents of the
+% ``Read Me'' file. That file serves a double purpose,
+% since it also constitutes the beginining of the
+% programmer's documentation. What better thing, after
+% all, to have appear at the beginning of the
+% typeset documentation?
+%
+% A good discussion of how to write a ReadMe file can be found in
+% Engst, Tonya, ``Writing a ReadMe File? Read This''
+% \emph{MacTech} October 1998, p. 58.
+%
+% Note the appearance of the
+% \cmd\StopEventually\ command, which marks the
+% dividing line between the user documentation
+% and the programmer documentation.
+%
+% The usual user will not be asked to
+% do a full build, not to speak
+% of the bootstrap.
+% Instructions for carrying out these procedures
+% begin the programmer's manual.

+the same license under which all the portions of \LaTeX\ itself are distributed.
+Please see \url{http://ctan.tug.org/macros/latex/base/lppl.txt} for details.
+
+To use this document class, you must have a working
+\TeX\ installation equipped with \LaTeXe\
+and possibly pdftex and Adobe Acrobat Reader or equivalent.
+
+To install, retrieve the distribution,
+unpack it into a directory on the target computer,
+and move the file \file{ltxutil.sty}
+into a location in your filesystem where it will be found by \LaTeX.
+
+To use, read the user documentation \file{ltxutil.pdf}.

+
+\section{Processing Instructions}
+
+The package file \file{ltxutil.sty}
+is generated from this file, \file{ltxutil.dtx},
+using the {\sc docstrip} facility of \LaTeX
+via |tex ltxutil.dtx| (Note: do \emph{not} use \LaTeX\ for this task).
+The typeset documentation that you are now reading is generated from
+the same file by typesetting it with \LaTeX\ or pdftex
+via |latex ltxutil.dtx| or |pdflatex ltxutil.dtx|.
+
+\subsection{Build Instructions}
+
+You may bootstrap this suite of files solely from \file{ltxutil.dtx}.
+Prepare by installing \LaTeXe\ (and either tex or pdftex) on your computer,
+then carry out the following steps:
+\begin{enumerate}
+\item
+Within an otherwise empty directory,
+typeset \file{ltxutil.dtx} with \LaTeX\ or pdflatex;
+you will obtain the typeset documentation you are now reading,
+along with the file \file{README-LTXUTIL}.
+
+Note: you will have to run \LaTeX, then
+\file{makeindex} \texttt{-s gind.ist ltxutil.idx}, then
+\file{makeindex} \texttt{-s gglo.ist -o ltxutil.gls ltxutil.glo}, then
+\LaTeX\ again in order to obtain a valid index and table of contents.
+\item
+Now typeset \file{ltxutil.dtx} with \TeX (not \LaTeX),
+thereby generating the package file \file{ltxutil.sty}.
+\item
+Install the following files into indicated locations within your
+TDS-compliant \texttt{texmf} tree (you may need root access):
+\begin{itemize}
+\item
+\file{$TEXMF/}\file{tex/}\file{latex/}\file{revtex/}\classname{ltxutil.sty}
+\item
+\file{$TEXMF/}\file{source/}\file{latex/}\file{revtex/}\classname{ltxutil.dtx}
+\item
+\file{$TEXMF/}\file{doc/}\file{latex/}\file{revtex/}\classname{ltxutil.pdf}
+\end{itemize}
+where \file{$TEXMF/} stands for \file{texmf-local/}, or some other \texttt{texmf} tree
+in your installation.
+\item
+Run \texttt{mktexlsr} on \file{$TEXMF/} (you may need root access).
+\item
+Build and installation are now complete;
+now put a \cmd\usepackage\texttt{\{ltxutil\}} in your document preamble!
+\end{enumerate}

+\subsection{Change Log}
+\changes{4.0b}{1999/06/20}{AO: Fixed spurious \texttt{CR} and (return) characters in output file. Also, if the document did not have the \cs{end}\texttt{figure} on a line of its own, the macro wouldn't work. Fixed.}

+% \subsection{The Document Body}
+%
+% Here is the document body, containing only a
+% \cmd\DocInput\ directive---referring to this very file.
+% This very cute self-reference is a common \classname{ltxdoc} idiom.
+% \begin{macrocode}
+\begin{document}%
+\expandafter\DocInput\expandafter{\jobname.dtx}%
+\end{document}

+%
+% \section{Using this package}
+% Once this package is installed on your filesystem, you can employ it in
+% adding functionality to \LaTeX\ by invoking it in your document or document class.
+%
+% \subsection{Invoking the package}
+% In your document, you can simply call it up in your preamble:
+% \begin{verbatim}
+%\documentclass{book}%
+%\usepackage{ltxutil}%
+%\begin{document}
+%<your document here>
+%\end{document}\end{verbatim}
+% However, the preferred way is to invoke this package from within your
+% customized document class:
+% \begin{verbatim}
+%\NeedsTeXFormat{LaTeX2e}[1995/12/01]%
+%\ProvidesClass{myclass}%
+%\RequirePackage{ltxutil}%
+%\LoadClass{book}%
+%<class customization commands>
+%\endinput\end{verbatim}
+%
+% Once loaded, the package gives you acccess to certain procedures,
+% usually to be invoked by a \LaTeX\ command or environment, but not at the document level.
+%
+%
+% \section{Compatibility with \LaTeX's Required Packages}
+% Certain packages, usually ones written by members of the
+% \LaTeX\ Project itself, have been designated ``required'' and
+% are distributed as part of standard \LaTeX.
+% These packages have been placed in a priviledged position
+% vis \'a vis the \LaTeX\ kernel in that they override the definitions of certain kernel macros.
+%
+% The \classname{ltxutil} package will be incompatible with any package that
+% redefines any of the kernel macros that \classname{ltxutil} patches---if that
+% package is loaded \emph{after} \classname{ltxutil}. This means that for
+% greatest compatibility, \classname{ltxutil} should be loaded \emph{after},
+% say, \classname{ftnright}, which overwrites \LaTeX's kernel
+% procedures \cmd\@outputdblcol, \cmd\@startcolumn, and \cmd\@makecol.
+%
+% Hereinafter follows some notes on specific \LaTeX\ packages.
+%
+% \subsection{array}
+% This package alters the way tabular environments are done,
+% therefore it could run afoul of the \LaTeX\ ``required'' package \classname{array} or any
+% package that calls for it to be loaded.
+% However, this package has provisions for remaining compatible with \classname{array}.
+% So long as the version of \classname{array} that is used with this package has the appropriate
+% meanings for the procedures it overwrites, all should be well.
+%
+% \subsection{longtable}
+% David Carlisle's \classname{longtable} package modifies both the \LaTeX\ kernel and the
+% \classname{array} package. This package must therefore alter \cmd\LT@array.
+% For now, that job is handled by \classname{ltxgrid}.
+%

+%
+% \section{Implementation of package}
+%
+% Special acknowledgment: this package uses concepts pioneered
+% and first realized by William Baxter (mailto:web at superscript.com)
+% in his SuperScript line of commercial typesetting tools, and
+% which are used here with his permission.

+% \subsection{Begin Document Structure}
+% The standard \LaTeX\ mechanism \cmd\AtBeginDocument\
+% is inadequate because the \cmd\vsize\ is bound much too early.
+% We supply here a mechanism whereby decisions about the
+% page layout can be deferred until \cmd\AtBeginDocument\ time.
+%
+% The problem we are working around is that the \cmd\AtBeginDocument\
+% hook in \cmd\document\ appears long after the calculation of
+% \cmd\vsize\ and \cmd\hsize, that is, \LaTeX\ provides no mechanism
+% for deferring the decision about the page grid until \cmd\AtBeginDocument\ time.
+% We fix things by prepending a hook at the very beginning of \cmd\document.
+%
+% As it turns out, though, it appears feasible to simply invoke the desired
+% column grid command at \cmd\AtBeginDocument\ time, since the MVL has nothing in it
+% at that time that would be problematical.
+%
+% The facility depends on the stability of this part
+% of \LaTeX's kernel code (the first token of \cmd\document),
+% which could change, you see. But considering that \LaTeX\ is
+% at this point essentially stagnant once more, we risk it.
+%
+% \begin{macro}{\document}
+% We begin by installing hooks into \cmd\document\ that
+% we will manage ourselves.
+% First, we do as \cmd\document\ does: end the group
+% begun by \cmd\begin. Last, we conclude our shenanigans by absorbing
+% the first token of the expansion of \cmd\document, which
+% we assume to be \cmd\endgroup.

+%
+% Read in the given file as if it were a document class file.
+% Usage: \cmd\class@extensionfile\ \arg{class} \cmd\@extension,
+% where \marg{class} is a file (similar to \file{aps.rtx}) and where \cmd\@extension\ is
+% the file extension for \marg{class}.

+% We repair an error in the \LaTeX\ kernel (see \file{ltfloat.dtx}) involving footnotes.
+% The symptom is that the \cmd\footnotemark\ command does not work properly within a \env{minipage} environment.
+% The source of the problem is in the way the \cmd\footnotemark\ and \cmd\@xfootnotemark\ procedures are defined:
+% they do not share the method, used by \cmd\footnote\ and other procedures, that allows a context switch to
+% change the way footnotes behave within a minipage environment.
+% This is a \LaTeX\ bug of long standing; our fix dates to 1987.
+%
+% While we are at it, we rewrite both the \cmd\footnote, \cmd\footnotemark\ and \cmd\footnotetext\ procedures,
+% achieving a cleaner separation of syntax and semantics.
+% Note that the \cmd\@footnotetext\ procedure is not involved in context switching;
+% \classname{hyperref} will take over that procedure, substituting its own processing around
+% its argument and passing this to \cmd\H@@footnotetext.
+% We anticipate this, and do our context switching on \cmd\H@@footnotetext.
+%
+% The \cmd\@makefnmark\ continues as the method of formatting the footnote mark.
+%
+% A note about the context switch mentioned above:
+% the \env{minipage} environment executes the following in order to alter the way footnotes
+% behave:\begin{verbatim}
+%\def\@mpfn{mpfootnote}%
+%\def\thempfn{\thempfootnote}%
+%\let\@footnotetext\@mpfootnotetext
+%\let\@makefnmark\@mpmakefnmark
+%\c@mpfootnote\z@\end{verbatim}
+% This code changes the counter used in autonumbered footnotes, the choice of footnote marker,
+% and the procedure used on the footnote text. Changing the counter is needed because minipage
+% footnotes are in their own sequence, and the footnote marker is customarily different within
+% a minipage. The procedure that works on the footnote text must be different because the footnotes
+% are placed at the bottom of the minipage, not the bottom of the text column.
+%
+% Note that \LaTeX\ initially defines \cmd\@mpfn\ as \texttt{footnote} and \cmd\thempfn\ as \cmd\thefootnote,
+% so we are initially doing general footnotes.
+%
+% Any procedure that establishes a minipage-like context (e.g., floats) can do the same as the mimipage context switch
+% illustrated above.

+%
+% Note on \classname{hyperref} compatibility:
+% In its ``Automated \LaTeX\ hypertext cross-references'',
+% the \classname{hyperref} package alters footnote processing,
+% but it does nothing to address the several issues of concern to us.
+%
+% The \classname{hyperref} package takes over the \cmd\@mpfootnotetext\ and
+% \cmd\@footnotetext\ procedures, wrapping the argument in its own code.
+% It also rewrites \cmd\@footnotemark, making it a hyperlink, and
+% \cmd\@xfootnotenext, removing from it all hypertext capabilities.
+%
+% However, if the \cmd\footnotemark\ command has been supplied with an optional argument,
+% \classname{hyperref}'s changes do not apply: it punts in this case.
+%
+% At the same time, it attempts to turn off its changes during
+% \cmd\maketitle\ processing, destroying one of the capabilities we desire.
+%
+% We make ourself \classname{hyperref} savvy:
+% we re-implement footnote processing, using \classname{hyperref} capabilities if that
+% package has been loaded.
+%
+% Any other package that rewrites \LaTeX's footnote macros will be incompatible
+% with this package.
+% \changes{4.1a}{2008/06/30}{(AO) Remove code that avoided changes to \cs{@xfootnotemark}}%
+%
+% Two thoughts about \classname{hyperref}: what for does it define \cmd\realfootnote?
+% Apparently even SR himself cannot remember.
+%
+% Also: a document class that desires high hypertext capabilities might
+% well wish to reimplement \cmd\maketitle\ so that footnotes called out from there
+% are hypertext links: the \classname{hyperref} package's
+% ``Automated \LaTeX\ hypertext cross-references''
+% does not do any of this:
+%\begin{quotation}
+% But the special footnotes in |\maketitle| are much too hard to deal with properly.
+% Let them revert to plain behaviour.
+%\end{quotation}
+% Note that the document class, in reimplementing \cmd\maketitle, must ensure
+% that the \classname{hyperref} package does not clobber its own definition!

+% \begin{macro}{\set@footnotewidth}
+% The two procedures \cmd\@footnotetext\ and \cmd\@mpfootnotetext\ share code.
+% We make that explicit here.
+%
+% Note that the procedure calling \cmd\make@footnotetext\ will open a group
+% with \cmd\bgroup\ which is then closed by \cmd\minipagefootnote@drop.
+%
+% Difference from \LaTeX: here we do not set \cmd\floatingpenalty\ to infinity.
+% Doing this must date back to a time when \LaTeX\ could not accomodate split insertions (footnotes).
+% I cannot think of any other reason to do have done this.
+% At any rate, with the \classname{ltxgrid} package, split insertions are properly
+% taken care of, so we allow it.
+%
+% We provide the hook \cmd\set@footnotewidth\
+% that sets the footnote on a particular measure.
+% Some page grids are such as to set a footnote in a context where \cmd\columnwidth
+% is not the right parameter to use for the set width of a footnote.
+% In such a case, for the applicable scope, you should define
+% \cmd\set@footnotewidth\ to perform this job correctly.
+%
+% If we are setting type on multiple page grids, we must still ensure that all footnotes that
+% find their way into the \cmd\footins\ insert register are set on the same width.
+% This implies the need for a document to have an ``overall'' page grid, which determines the set width of all footnotes
+% with the exception of minipage footnotes.
+%
+% In general, remember that footnotes, like all insertions (including floats),
+% are a step outside of the galley context, and all aspects of insertions need to be
+% properly handled, including the set width.

+% It also establishes a strut and null glue at the end of the last paragraph of the footnote;
+% The strut helps compensate for the lack of \cmd\interlineskip\ glue between \cmd\insert s;
+% the glue establishes a feasible \cmd\vsplit\ point between footnotes.
+%
+% Note that in the title block (\classname{ltxfront}), the alternative definition, under the name \cmd\frontmatter@footnotetext, is used.

+% \subsection{Floats}
+%
+% \subsubsection{Usage notes}%
+% We extend the \LaTeX\ kernel for three purposes:
+% \begin{enumerate}
+%
+% \item
+% When the \cmd\footnote\ command is used within the
+% scope of a float, we do as \env{minipage} does.
+%
+% \item
+% We provide a mechanism to write floats out to an external
+% stream for temporary storage (deferred floats).
+%
+% \item
+% We provide mechanism for placing a float \texttt{here}
+% invariably, that is, floats are unfloated.
+% This mechanism is used to read the external stream mentioned above.
+%
+% \end{enumerate}
+%
+% To use these mechanisms, the document class should
+% define a float, say, \env{figure} as per usual, and in addition:
+% \begin{enumerate}
+%
+% \item
+% Optionally define an alternative, say \env{figure@write} as follows:
+% \begin{verbatim}\newenvironment{figure@write}{%
+% \write@float{figure}%
+%}{%
+% \endwrite@float
+%}\end{verbatim}
+% That is, the alternative environment executes \cmd\write@float\
+% instead of \cmd\@float.
+% Note that this step is not needed if the float environment
+% is defined in the simple way of \file{classes.dtx}.
+% However, an environment like \env{longtable} will require it.
+%
+% \item
+% Install into \cmd\AtBeginDocument\ a call to \cmd\do@if@floats,
+% with the float name and an appropriate file extension as its arguments.
+% \begin{verbatim}\appdef\class@documenthook{\do@if@floats{figure}{.fgx}}\end{verbatim}
+%
+% \item
+% Optionally define a text entity \cmd\figuresname\ that will
+% be the text of the head that is set over the
+% deferred floats.
+% If not defined, there will be no head.
+%
+% \item
+% Optionally define a user-level command to allow
+% the document to determine where the figures are printed out
+% (default is to print at end of document). E.g.,
+% \begin{verbatim}\newcommand\printfigures{\print@float{figure}}\end{verbatim}
+% \item
+% Install into \cmd\appdef\cmd\class@enddocumenthook\ a call to \cmd\printfigures,
+% or, if the latter is not defined, as follows:
+% \begin{verbatim}\appdef\class@enddocumenthook{\print@float{figure}}\end{verbatim}
+% Note that installing this command into \cmd\AtBeginDocument
+% is best done earlier than calls that assume the last page of
+% the document is at hand.
+%
+% \end{enumerate}
+%
+% \subsubsection{Robustifying fragile commands}%
+% Certain of \LaTeX's commands cannot be written out to a file or appear within a \cmd\mark\ command argument
+% because they do calculations during expansion.
+% We provide for a little help, but without changing the meanings of these commands.

+%

+% Patch the standard \LaTeX\ sectioning procedure to:

+% Allow a sectioning command to trigger the title page, or more generally
+% to recognize that it is the first object in the document,
+% so we headpatch \cmd\@startsection.
+%
+%\item
+% Allow a tail command in |#6| to uppercase the title, so we retain
+% DPC's braces.
+%
+%\item
+% Allow each type of sectioning command to format its number differently,
+% so we generalize \cmd\@seccntformat.
+%
+%\item
+% Allow each type of sectioning command to format its argument differently,
+% so we generalize \cmd\@hangfrom.
+%
+%\item
+% Allow the starred form of the command to
+% mark (the running head) and
+% make an entry in the TOC,
+% so we put \cmd\@ssect\ on the same footing as \cmd\@sect.
+%
+% Note that the tokens passed to the TOC now are \emph{not}
+% the optional argument of the command, but the required.
+% This means that the user can no longer use the former
+% to put variant content in to the TOC as the Manual says.
+%
+% Instead, the optional argument is used to put an alternative
+% title into the running headers, a better choice.

+% The procedure \cmd\@mkpream@relax\ participates in a strange and wonderful
+% method of binding the alignment procedure---but only certain parts thereof.
+%
+% Here is how it works: in \LaTeX, the \classname{array} package, and in the

+% preamble (using \cmd\@mkpream) for use by the upcoming \cmd\halign.
+% Then, in both \classname{array} and \classname{longtable}, \TeX's \cmd\edef\
+% is used to `compile in place' that alignment preamble.
+%
+% In the case of \classname{array},
+% the operation is done in order to pre-expand the use of \texttt{*};
+% in \classname{longtable}, it is to set the widths of the columns.
+%
+% Now, during this \cmd\edef, certain control sequence names must \emph{not}
+% be expanded, and those are robustified by \cmd\@mkpream@relax.

+% This document, when typeset, prompts for the name of a LaTeX auxiliary (.aux) file
+% and then processes that file, paying attention to
+% keys that have been cited (via \citation)
+% or defined (via \bibcite).
+% It then prints out diagnostics indicating
+% * any keys that were cited but never defined,
+% * any keys that were defined but never cited, and
+% * keys that were cited and defined, but not in the same order.
+%
+% BibTeX takes care of such things automatically,
+% so there is little use for such a test when using BibTeX.
+%
+% A separate question: will this file run under revtex4.cls?
+% I can see two lines in my .aux with the potential for problems:

+%\begin{verbatim}
+%revtex4-1.dtx
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{tex revtex4-1.dtx}}%
+% Typesetting ths file under \TeX\ itself runs the installer,

+%\begin{verbatim}

+%aps10pt4-1.rtx, aps11pt4-1.rtx, aps12pt4-1.rtx, revsymp.sty
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{pdflatex revtex4-1.dtx}}%
+% Typesetting the source file under \LaTeX\
+% generates the documentation.
+%\begin{verbatim}
+%revtex4.pdf,
+%\end{verbatim}
+%
+% \subsubsection{Auxiliary}%
+% The following are auxiliary files generated
+% in the course of running \LaTeX:
+% \begin{verbatim}
+%revtex4.aux revtex4.idx revtex4.ind revtex4.log revtex4.toc
+% \end{verbatim}
+%
+% \section{Code common to all modules}%
+%
+% The following may look a bit klootchy, but we
+% want to require only one place in this file
+% where the version number is stated,
+% and we also want to ensure that the version
+% number is embedded into every generated file.
+%
+% Now we declare that
+% these files can only be used with \LaTeXe.
+% An appropriate message is displayed if
+% a different \TeX{} format is used.

+% \section{The driver module \texttt{driver}}
+%
+% This module, consisting of the present section,
+% typesets the programmer's documentation,
+% generating the \file{00readme.txt} and sample document as needed.
+%
+% Because the only uncommented-out lines of code at the beginning of
+% this file constitute the \file{driver} module itself,
+% we can simply typeset the \file{.dtx} file directly,
+% and there is thus rarely any need to
+% generate the ``driver'' {\sc docstrip} module.
+% Module delimiters are nonetheless required so that
+% this code does not find its way into the other modules.
+%
+% The \enve{document} command concludes the typesetting run.
+%
+% \begin{macrocode}
+%<*doc>
+% \end{macrocode}
+% The driver uses packages \file{ltxdoc.sty}, \file{ltxdocext.sty},
+% \file{hyperref.sty}, and whatever font package has been selected.
+% \begin{macrocode}
+\documentclass{ltxdoc}
+\RequirePackage{ltxdocext}%
+\let\url\undefined
+\RequirePackage[colorlinks=true,linkcolor=blue]{hyperref}%
+\expandafter\ifx\csname package@font\endcsname\@undefined\else
+ \expandafter\RequirePackage\expandafter{\csname package@font\endcsname}%
+\fi
+% \end{macrocode}
+% We ask for the usual indices and glossaries.
+% \begin{macrocode}
+\CodelineIndex\EnableCrossrefs % makeindex -s gind.ist revtex4
+\RecordChanges % makeindex -s gglo.ist -o revtex4.gls revtex4.glo
+% \end{macrocode}
+%
+% \subsubsection{Docstrip and info directives}
+% We use so many {\sc docstrip} modules that we set the
+% \texttt{StandardModuleDepth} counter to 1.
+% \begin{macrocode}
+\setcounter{StandardModuleDepth}{1}
+% \end{macrocode}
+% The following command retrieves the date and version information
+% from this file.

+%
+% \section{Overview}%
+% \revtex\ is a \LaTeXe\ document class, somewhat like a hybrid of
+% the standard \LaTeX\ \classname{book} and \classname{article} classes.
+%
+% Certain packages are (should be) loaded by this class in any case:
+% \classname{amssymb}, \classname{amsmath}, \classname{bm}, \classname{natbib}.
+%
+% Certain packages are automatically loaded by this class
+% when a corresponding class option has been invoked:
+%
+% \begin{tabular}{ll}
+% \textbf{\revtex\ option}&\textbf{package}\\
+% \classoption{amsfonts}&\classname{amsfonts}\\
+% \classoption{amssymb}&\classname{amssymb}\\
+% \classoption{aps}&\classname{overcite}\\
+% \end{tabular}
+%
+% Certain other packages are to be loaded by the
+% document through explicit use of \cmd\usepackage.
+% Some mentioned in the user documentation are
+% \classname{graphicx}, \classname{longtable}, \classname{hyperref},
+% and \classname{bm}.
+%
+% Certain commonly used packages are known to be incompatible with
+% \revtex, among them \classname{multicol} and \classname{cite}.
+% If such a package is found to be loaded, \revtex\ issues an error message
+% and halts the job.
+% Halting might be considered severe punishment for loading an incompatible
+% package, but if we were to proceed, an even weirder error might be encountered
+% further down the road.
+%
+% This document class implements the substyle: a set of mutually
+% exclusive class options that, in this case, allow the
+% document class to address multiple societies.
+% It also implements a sub-substyle, giving the
+% journal of the given society.
+% Any society may create a substyle;
+% this file generates one for \classoption{aps}.
+%
+% FIXME: should always load the \classname{graphicx} package. No, allow user to load whichever graphics package is desired.
+%
+% QUERY: since \classname{amsfonts} and \classname{amssymb} extend
+% syntax, why not load them in any case?
+%
+% Certain processing occurs at the endgame for reading in \revtex, thereby establishing
+% precedence for assignments to \LaTeX's (and \revtex's) parameters:
+% \begin{enumerate}
+% \item
+% Figure out which society is operative and read in the indicated \file{.rtx} file.
+% \item
+% Figure out which journal option is operative and execute the indicated journal command. This may lead to reading in a journal substyle \file{.rtx} file.
+% \item
+% Figure out which pointsize is operative and execute the indicateded pointsize command. This may lead to reading in a pointsize \file{.rtx} file.
+% \item
+% Execute all of the document's options, in the order declared within the document.
+% \item
+% Read in all required packages (like \classname{natbib}, \classname{amsfonts}, \classname{amssymb}), that were determined by class, society, and journal.
+% \item
+% The last required package, if existing, is the document's style file, the \file{.rty} file.
+% Note that the \file{.rty} file can override the assignments of \revtex, society, journal, and required packages, and even load its own packages.
+% It can also, via appendations to \cmd\setup@hook, override the setup code itself.
+% \item
+% Execute all of the setup code accumulated. Such code can be queued by \revtex\ itself, by the society, by the journal, or by the pointsize.
+% \item
+% At this point, \revtex\ has completed the process of inputting itself,
+% and \LaTeX\ will now execute the \cmd\AtEndOfClass\ procedures.
+% \end{enumerate}
+%
+% \revtex\ will have enqueued code to execute at \cmd\AtBeginDocument\ time,
+% in two different queues.
+% \cmd\document@inithook\ executes immediately upon encountering the \cmd\begin\env{document} statement,
+% \cmd\class@documenthook\ at the end of all the code enqueued via \cmd\AtBeginDocument.
+% \begin{enumerate}
+% \item
+% Install procedures to execute at the very end of the class's
+% \cmd\AtBeginDocument\ processing, such as
+% \begin{enumerate}
+% \item
+% closing out the page grid
+% \item
+% putting out the LastPage label.
+% \item
+% issuing a \cmd\bibliographystyle\ command, based on the value set
+% by the society substyle.
+% \item
+% setting default values for parameters used in the document.
+%FIXME: differentiate between class's parameters that can wait until
+% they are used in the document, and parameters that are used at \cmd\AtBeginDocument\ time.
+% \end{enumerate}
+% \item
+% Install procedures to execute the very last at \cmd\AtEndDocument\ time,
+% such as the \cmd\clearpage\ processing.
+% \end{enumerate}
+%
+% Certain events are optionally scheduled for \cmd\AtBeginDocument\ time:
+% \begin{enumerate}
+% \item
+% Setting default values for the Booleans and for other procedures used in formatting.
+% \item
+% In response to class options options, adjusting parameters and procedures used in formatting.
+% \item
+% Implementing the \classoption{eqsecnum} option, if required.
+% \item
+% Setting the state engine for data commands.
+% \item
+% Memorizing procedures for later use.
+% \item
+% Setting type size and area, for use by later calculations.
+% \end{enumerate}
+%
+% Certain events are scheduled for \cmd\class@enddocumenthook\ time:
+% \begin{enumerate}
+% \item
+% Print out the migrated floats or the end notes, if needed.
+% \item
+% Close out the page grid.
+% \item
+% Label the last page of the document
+% \item
+% (\classname{natbib}) prepare to read in the \file{.aux} file.
+% \end{enumerate}
+%
+% \section{Writing journal-specifc extensions to \revtex}
+%
+% With this version of \revtex, we introduce a somewhat different
+% scheme for adapting \revtex\ to the needs of a specific journal.
+%
+% To create a journal substyle, you create new class options in
+% \revtex\ for the society, say \classoption{osa}, and any of that society's journals,
+% one of which is, say, \classoption{josaa},
+% using the code for the APS as a guide.
+% In particular, each of your new options should separately define \cmd\@society\
+% and \cmd\@journal. That for the former will be the same for
+% all options relating to a particular society.
+%
+% Then, for the society, you create a corresponding \file{.rtx}
+% file, in our case \file{osa.rtx}.
+% Within that file, you override procedures and parameter assignments as you see fit.
+% Ideally they will be generally applicable to all of that society's
+% journals (see the file \file{aps.rtx} for a realization of this scheme).
+% Also within that file, you include a
+% section of code for each journal, that for josaa looks like:
+% \begin{verbatim}
+% \@ifx{\@journal\journal@josaa}{%
+% <code specific to the josaa>
+% }{}%
+% \end{verbatim}
+%
+% Thus far, the scheme is similar to that used in \revtex\ 3.1.
+% However, the new scheme does differ from the old in that
+% the \file{.rtx} file should define no syntactical extensions
+% to \revtex.
+%
+% \section{The \classname{revtex4} Document Class}
+% Above, we took
+% advantage of 1) the \LaTeX\ definition of \cmd\ProvidesPackage\ and
+% 2) that the line of code immediately afterwards follows the \cmd\ProvidesClass\ statement above.

+% \section{Compatability with the geometry package}
+%
+% The \classname{geometry} package of Hideo Umeki provides a way to
+% specify the metrics of the media and page layout.
+% We want to ensure that \revtex\ does not foreclose on the use of
+% this or any other such package, nor to interfere with
+% explicit assignments of such metric parameters within the
+% document preamble.
+%
+% The \LaTeX\ parameters (resp. \TeX\ primitives) set by \classname{geometry} are:
+% \cmd\paperwidth, \cmd\paperheight,
+% \cmd\textwidth, \cmd\textheight,
+% \cmd\topmargin, \cmd\headheight, \cmd\headsep,
+% \cmd\footskip, \cmd\skip\cmd\footins,
+% \cmd\marginparwidth, \cmd\marginparsep,
+% \cmd\oddsidemargin, \cmd\evensidemargin,
+% \cmd\columnsep,
+% \cmd\hoffset, \cmd\voffset, \cmd\mag,
+% \cmd\if@twocolumn, \cmd\if@twoside, \cmd\if@mparswitch, \cmd\if@reversemargin,
+%
+% \revtex's assignments can be overridden by
+% any package or other statement in the document preamble,
+% so it should be compatible.
+%
+%FIXME: one parameter is rendered semantically void (by \file{ltxgrid.dtx}):
+% \cmd\if@twocolumn.

+%
+% \subsubsection{Bibliography}
+%
+% Load Patrick Daly's \classname{natbib} package,
+% \url{ftp://ctan.tug.org/macros/latex/contrib/supported/natbib}
+%
+% Note that \classname{natbib} assumes that it loads
+% over a document class, such as the \classname{article} class,
+% that has already defined \env{thebibliography} and \cmd\@listi.
+%
+% Note also that \classname{natbib} also installs a command
+% \cmd\NAT@set@cites\ into \cmd\AtBeginDocument\ which presumes
+% that the proper \cmd\bibpunct\ command has been issued.
+%
+% Note that the macro \cmd\NAT@sort\ controls
+% whether citations are left alone (\cmd\NAT@sort=0), sorted (\cmd\NAT@sort=1), or sorted and compressed (\cmd\NAT@sort=2).
+% Since we give \classname{natbib} the \classoption{sort\&compress} option,
+% if you prefer \classoption{sort}, you need only \cmd\let \cmd\NAT@sort\ to be \cmd\@ne.
+% However, if you prefer the effect of having neither \classoption{sort} nor \classoption{sort\&compress},
+% you must \cmd\let \cmd\NAT@sort\ to be \cmd\z@ and you must also define
+% \cmd\let\cmd\NAT@cmprs\ to be \cmd\z@.
+%
+% As of version 8.2, \classname{natbib} now no longer binds at the point where it is read in.
+% This means that we can freely change \cmd\NAT@sort, \cmd\NAT@cmprs, and the new
+% \cmd\NAT@merge. Henceforth, we require that this later version be used.
+%
+% For other \classname{natbib} customizations, you may proceed as if you were going to use
+% the \file{natbib.cfg} file: anything that you can modify by this means is fair game.
+% Once \revtex\ is finished loading, you can assert any definitions for \classname{natbib} that you wish.

+% \cmd\rev@citet\ that of \cmd\textcite.
+%
+% In each case, we invoke \cmd\rtx@swap@citea\ to effect different productions between
+% multiple arguments to the \cmd\cite\ command.
+%
+% \cmd\rev@citealpnum\ provides textual citations where superscript citations are the default.

+% The procedures |\rtx@def@citea|, |\rtx@def@citea@close|, and |\rtx@def@citea@box|

+%
+% \changes{4.1j}{2009/10/25}{(AO, 552) Repair spacing in \cs{onlinecite}}
+% In these procedures, we use \cmd\count@\ to count the number of arguments of the \cmd\cite\ command,
+% and we use \cmd\c@NAT@ctr\ to keep track of which argument we are processing.
+% The latter counter is created by \classname{natbib} and used there solely in bibliography processing,
+% where it keeps track of the reference number.
+% We take over its use in these macros, but only locally; therefore these procedures should work properly, even within the bibliography.
+%FIXME: check whether this is true!
+%
+% Because we are using a scratch counter \cmd\count@, we are vulnerable to other \TeX\ programmers
+% who patch in to \classname{natbib}'s processing and who might use that counter at the same time we are doing so.
+% This is a potential source of trouble for us.
+%FIXME: store the value of \cmd\count@\ in a private \cmd\csname!
+%
+% Note that \cmd\rtx@def@citea\ begins the same as \cmd\NAT@def@citea, which it replaces,
+% then makes further decisions based on the values of the counters.
+%
+% Note also that, in \classname{natbib}, the replacement part of \cmd\NAT@def@citea@close\ could be rewritten as
+% \cmd\NAT@def@citea\cmd\prepdef\cmd\@citea\verb+{+\cmd\NAT@@close\verb+}+, which
+% would them obviate the need for us to override its meaning.
+%
+% Note, too, the effect of \cmd\rtx@def@citea@box, which replaces \cmd\NAT@def@citea@box,
+% is almost the same as the latter, except the entire \cmd\@citea\ is given as the argument
+% of \cmd\NAT@mbox.

+% We wish to extend \classname{natbib} to move spaces and citations around
+% a superscript-style citation, imitating Donald Arseneau's \classname{cite} package
+% with the \classoption{super}.
+%
+% The \cmd\rtx@@citetp\ procedure is substituted for \cmd\NAT@@citetp;
+% it then calls the \cmd\rtx@citex\ procedure and implements the features of the
+% \classoption{citeautoscript} class option.
+% In the end, \cmd\@citex\ is called with its customary parameters.
+%
+% The document should be marked up as if citations were \emph{not} superscripted,
+% and then if you select a journal substyle that has superscripted citations, \revtex\ will do its best
+% to alter the formatting of the \cmd\cite s to accomodate superscript style.
+%
+% Only citations set as superscript are affected by this procedure,
+% because we check \cmd\@cite\ against \cmd\NAT@citesuper.
+%
+% Here's a subtle point: when is the argument of \cmd\super@cite@swap\ not the same as the token \cmd\@let@token?
+% Answer: when the latter is \cmd\@sptoken! This case has to be handled separately.
+%
+% Note that whether a punctuation is movable is determined by the definition
+% of a particular control sequence name.
+% A society or journal can alter things: to remove a character from the set,
+% do, say, \cmd\expandafter \cmd\let \cmd\csname \texttt{rtx@automove;} \cmd\endcsname \cmd\relax.
+% To add a character to the set, do, say, \cmd\expandafter \cmd\let \cmd\csname \texttt{rtx@automove;} \cmd\endcsname \cmd\@empty.
+%
+% Implementation note: due to a \TeX\ peculiarity, we have to check for the case
+% where \cmd\@let@token\ is a space token \emph{before} we parse forward.
+% At issue is the corner case where an end of file is at hand. If we
+% were to let \cmd\super@cite@swap\ parse forward, we would encounter a \TeX\ end-of-file
+% error. Note that the test will be true in many distinct cases:
+% the file ends, the next character is a line terminator, the next character is a space.

+% \section{Initial setup}
+%
+% The standard LaTeX document classes execute certain commands
+% that are best deferred until \cmd\class@documenthook\ time.
+% Here, we effectively split \cmd\pagenumbering\ into two halves,
+% with a default definition for \cmd\thepage
+% and an initialization of \cmd\c@page\ at \cmd\class@documenthook\ time.
+%
+% The meaning of \cmd\thepage\ can be overridden by society, journal, or
+% anywhere within the document pramble, and the counter itself will be
+% preset at the beginning of the document.
+% \begin{macrocode}

+% \changes{4.0b}{1999/06/20}{Defer assignment until \cs{AtBeginDocument} time.}

+% When setting the column grid, we have to override the procedure
+% for formatting lists.

+% typesetting must employ only the manipulation of
+% \cmd\leftskip\ and \cmd\rightskip, and must avoid the use of
+% \cmd\moveleft, \cmd\moveright, and \cmd\parshape.
+%
+% It is one of the stranger features of \TeX\ that these two separate
+% mechanisms exist. The latter three have the effect of adding things to the
+% Main Vertical List that cannot be removed and later added back with all their
+% properties intact.
+%
+% In detail, \cmd\moveleft, say, adds a box to the MVL with
+% its reference point shifted horizontally by some amount relative to the
+% reference point of the enclosing list. If that box is removed from the
+% MVL (via a \cmd\lastbox\ operation in the output routine), and later
+% thrown back to the MVL, the shift of the box will have been ``forgotten'' by \TeX.

+% \section{Patches for lineno.sty}
+%
+% The \classname{lineno} package detects the case where the package has been loaded
+% and the document invokes \cmd\linelabel, but the \cmd\linenumbers\ command has not been
+% issued: it treats this case as an error.
+%
+% It is wrong for validity of document syntax to be dependent upon package semantics:
+% we make the condition a warning rather than an error.
+%
+% \begin{macrocode}
+\def\@LN@LLerror@org{%
+ \PackageError{lineno}{%
+ \string\linelabel\space without \string\linenumbers
+ }{%
+ Just see documentation. (New feature v4.11)%
+ }%
+ \@gobble
+}%
+\def\@LN@LLerror@ltx{%
+ \PackageWarning{lineno}{%
+ To make the \string\linelabel\space command work, you must issue the \string\linenumbers\ command
+ }%
+ \@gobble
+}%
+% \end{macrocode}
+%
+% If appropriate, enable line numbering within the abstract.
+%
+% This mechanism applies generally:
+% Create the box in a context in which the meaning of \cmd\par\ has been patched by \classname{lineno},
+% then \cmd\unvbox\ the box in a context where \cmd\set@linepenalties\ has been executed, and
+% follow up with \cmd\@linenumberpar, which forces a visit to the output routine just there.
+% Note that here, we have to de-fang \cmd\@LN@parpgbrk, which would otherwise causes the appearance
+% of a box with depth -1000 points. Go figure.
+% \begin{macrocode}
+\appdef\class@documenthook{%

+}%
+% \end{macrocode}
+%
+% One may well ask: how to obtain line numbering within an alignment in a float?
+% This objective, along with line numbering within footnotes, would require extraordinary measures.
+% The float would have to be thrown onto the MVL in order to acquire its line numbers, but
+% that fragment of MVL would then have to be protected from being shipped out.
+% The question of how to coordinate those lines' numbers with those of lines in the MVL would
+% also require dealing with.
+%
+% \section{Endgame for the Document Class}
+%
+% We provide for a ``job macro package'' that can override
+% definitions and assignments made by the class or any other packages it loads.
+%
+% \subsection{Job Macro Package}
+% You can create a ``job macro package'' for your document
+% that will be read in automatically every time
+% your document is processed.
+% Thus, if your job is a file called \file{myarticle.tex},
+% then the file \file{myarticle.rty} will be read in
+% just the same as if you had placed a
+% \cmd\usepackage|{myarticle.rty}| statement
+% immediately following your \cmd\documentclass\ statement.
+%
+% Within your \file{.rty} file,
+% you can define and use control sequence names that use the |@| character
+% and you can override any of the definitions or assignments made
+% by the \revtex\ document class or the selected journal substyle.
+% That is, you have the power to really mess things up badly.
+%
+% If you choose to have a job macro package, you are well
+% advised to read the \LaTeX\ guide to document classes,
+% \file{clsguide.tex} or read up on the subject
+% in a book like the \LaTeX\ Companion.
+%
+% The file \file{template.rty} contains a template for
+% creating your own job macro package.
+%
+% \begin{macrocode}
+\appdef\rtx@require@packages{%
+ \InputIfFileExists{\jobname.rty}{}{}%
+}%
+% \end{macrocode}
+%
+% \subsection{Endgame Processing for the Document Class}
+%
+% The remaining steps in processing the document class involve
+% determining the needed society, journal, and pointsize from
+% the document's class options and inputting the needed files or
+% executing the indicated procedures.
+%
+% Note that the society file is expected to declare options that will
+% allow us to determine the journal involved, and the society and journal
+% themselves determine the which pointsize options are declared, along with
+% their meanings.
+%
+% Note also that required packages are read in only after the document options
+% have been processed, because the latter can affect the former.
+%
+% Finally, the setup code is executed: this is code that depends on the
+% meanings of the switches we define and on the code within the packages we load.
+%
+% Note that there are other hooks in use: \cmd\document@inithook, which is
+% executed right at the beginning of the document, and \cmd\class@documenthook,
+% which serves as a vehicle for any \cmd\AtBeginDocument\ code we might wish to
+% execute.
+%
+%FIXME: use \cmd\class@documenthook\ only for things that bear on the MVL;
+% use \cmd\document@inithook\ for all patches to procedures defined within the preamble.
+%
+% Remember that \classname{natbib} changes its state at \cmd\AtBeginDocument\ time,
+% so we have to install our own code at a later point in the processing.
+%
+% We determine the proper \cmd\@society\ by examining the document's class options.
+% \begin{macrocode}
+\@parse@class@options@society
+% \end{macrocode}
+%
+% Then, we input the society's substyle
+% (which may in turn lead to loading a journal substyle or a pointsize substyle).
+% The substyle should not assume the value of any class option:
+% instead, it should install code into \cmd\setup@hook.
+% \begin{macrocode}
+\@process@society{aps}%
+% \end{macrocode}
+%
+% Now that the society has defined the class options relating to journals,
+% and has defined \cmd\@journal@default, we can process the journal substyle.
+% We parse the options for one that sets \cmd\@journal.
+% \begin{macrocode}
+\@parse@class@options@\@journal
+% \end{macrocode}
+% And we process the journal.
+% Note that \emph{it is an error} for a society file to fail to define
+% \cmd\@journal@default.
+%
+% \begin{macrocode}
+\expandafter\@process@journal\expandafter{\@journal@default}%
+% \end{macrocode}
+%
+% Now that the society and journal have finished defining any options relating to
+% point size, we process the class options for any that set \cmd\@pointsize.
+% \begin{macrocode}
+\@parse@class@options@\@pointsize
+% \end{macrocode}
+% And we process the pointsize.
+% Note that it is an error for the society and journal to leave \cmd\@pointsize@default\
+% undefined at this point, however, the journal may have overriden the assignment of the society.
+%
+% \begin{macrocode}
+\expandafter\@process@pointsize\expandafter{\@pointsize@default}%
+% \end{macrocode}
+%
+% Next, we process the class options for once and all.
+% Doing so sets values for some of the Booleans that were introduced along with
+% the \cmd\DeclareOption\ statements above.
+%
+%CHANGE: We process the options in the order declared in the document; this
+% gives the document greater control.
+%
+% \begin{macrocode}
+\@options
+% \end{macrocode}
+%
+% Now that the class options have been processed, we can load all the
+% packages that we know need loading.
+% \begin{macrocode}
+\rtx@require@packages
+% \end{macrocode}
+%
+% At this point, the society substyle, the journal substyle, and the
+% pointsize have all been processed, along with the document class options.
+% Some of these have left things for later; we do these now.
+%
+% \begin{macro}{\setup@hook}
+%
+% This portion of the code for this class file
+% \emph{must} appear at the very end:
+% The procedure
+% \cmd\setup@hook\
+% should be executed at the very end of the class file.

+% \changes{4.0b}{1999/06/20}{AO: made aps.rtx part of revtex4.dtx}
+% The file \file{aps.rtx} is read in by the \classname{revtex4} document class
+% if \cmd\@society\ has the value \classoption{aps}.
+%
+% Here, code specific to APS journals is separated out from the \revtex\ document class.
+% (Other societies can customize \revtex\ by supplying their own \file{.rtx} file.)
+%
+% This class extension file is a model for a class extension you might write yourself.
+%
+% First, incorporate a \cmd\ProvidesFile\ command with an optional argument giving
+% the version information, e.g.,
+% \begin{verbatim}
+% \ProvidesFile{foo}[2001/09/11 v1.1 Docinfo]%
+% \end{verbatim}
+%
+% Within the society substyle, there are two things we must do as well:
+% define the default journal,
+% \begin{verbatim}
+% \def\@journal@default{pra}%
+% \end{verbatim}
+% And do likewise for the point size:
+% \begin{verbatim}
+% \def\@pointsize@default{10}%
+% \end{verbatim}
+%
+% We first define some text entities (amounting to journal abbreviations),
+% then some APS-specific initialisations,
+% then code for particular APS journals.
+% In the latter case, the choice is
+% keyed off the macro \cmd\@journal.

+% Apply to all APS journals; individual journals may override these settings.
+%
+% \begin{macro}{\@fnsymbol}
+% The \LaTeX\ kernel definition of \cmd\@fnsymbol\ is overridden.
+% The definition in \filename{fixltx2e.sty} serves as a guide to the new way to symbol,
+% working in both text- and math modes.
+%
+% \filename{fixltx2e.sty} duplicates some features of \filename{ltxgrid} and \filename{ltxutil},
+% however, so it may be incompatible with \revtex.
+% In case it is not loaded, we must provide a meaning for \cmd\TextOrMath,
+% which that package makes robust.
+% I believe that it is \cmd\@fnsymbol\ itself that ought to be robustified.
+% e\TeX\ further complicates matters; we do not especially accomodate it.

+% \subsubsection{Comparing apsrev.bst and apsrmp.bst}\label{sec:CompRevRmp}
+% These two bibliographic styles differ as follows:

+% \CandE{seq-no}%
+% Citation order (unsorted, like unsrt.bst)
+% \CandE{nm-init,ed-au}%
+% Initials + surname (J. F. Smith)
+% \CandE{blkyear}%
+% Missing date left blank
+% \CandE{date-nil-x}%
+% If date is empty, then do not produce the surrounding punctuation (parens, brackets, colon, comma)
+% \CandE{inproceedings-chapter}%
+% produce pages after chapter, just as in InBook
+% \CandE{techreport-institution-par}%
+% format tech report institution like book publisher
+% \CandE{vnum-x}%
+% Journal vol, without number as `34'
+% \CandE{pub-date}%
+% Publisher with address and date in parentheses (Oxford, 1994)
+% \CandE{pre-pub}%
+% Edition, publisher, volume, chapter, pages. Note that both use guard code pre-edn.
+% \end{itemize}
+%
+% \file{apsrmp.dbj} has the following guard codes, which \file{apsrev.dbj} does not:
+% \begin{itemize}
+% \CandE{nm-rev1}%
+% Only first name reversed, initials (AGU style: Smith, J. F., H. K. Jones)
+% \CandE{dt-beg}%
+% Date after authors
+% \CandE{vnum-sp}%
+% Journal vol (num) as `34 (2)'
+% \CandE{pp-last}%
+% Pages at end, but before any notes
+% \CandE{pub-par}%
+% Publisher in parentheses
+% \CandE{school-par}%
+% School/address in parens: `(school, address)'
+% \CandE{bkedcap}%
+% `Name Editor,' as above, editor upper case
+% \CandE{and-com}%
+% Comma even with 2 authors as `Tom, and Harry'
+%
+% \end{itemize}
+%
+% We ensure that the journal substyle has the first word

+%
+% After this substyle is read in, we will execute the code specific to the selected
+% journal: execute the society/journal \file{.rtx} file if it exists, or
+% execute the society/journal macro (if the latter is not defined, it will \cmd\relax\ out).

+%
+% Note: the convention in \revtex\ and its substyles is that
+% the substyle must not override any explicit class options
+% declared by the document.
+% This means that the various Booleans of Section~\ref{sec:options}
+% may be assigned here only if they are still undefined at this point.
+%
+% For the APS, we supply code specific to journals PRA, PRB, PRC, PRD, PRE, PRL, and RMP.
+% At present, they are identical,
+% with the exception of PRB and RMP.

+% \subsection{APS Sanity Checking}\label{sec:aps-sanity}
+% \changes{4.1f}{2009/07/20}{(AO, 524) Makes no sense if citations are superscript numbers and so are footnotes}
+%
+% Rule: if \cmd\place@bibnumber\ is \cmd\place@bibnumber@sup\
+% (citations are numbered and set superscript),
+% then it makes no sense for \cmd\footinbib@sw\ to be \cmd\false@sw\
+% (footnotes set in the bibliography, as endnotes).
+% If both conditions prevailed, then the document would have footnotes
+% and citations both as superscript arabic numbers, but independently numbered,
+% which would be confusing.
+%
+% Any society that provides for both superscript numbered citations as well as for
+% numbered footnotes should check for this same condition, and deal with it.
+%
+% Note: an alternative would be for footnotes to use the same sequence of footnote devices
+% that are used by the frontmatter footnotes
+% (\cmd\frontmatter@thefootnote\ instead of arabic numbers).
+%
+% In this case, we would want to refrain from resetting \cmd\c@footnote\ at the end of
+% the title page formatting.
+% We would also want to treat body footnotes identically to frontmatter footnotes:
+% the assignments in \cmd\titleblock@produce\ would persist throughout the document.
+%
+% But APS do not choose to go that route.
+% \begin{macrocode}
+\appdef\setup@hook{%

+% The following commands effectively establish the style in which \cmd\cite\ commands are
+% formatted.
+% You can think of them as the second needed component for the bibliography.
+%
+% Set up for author-year citations:
+% when \cmd\NAT@set@cites\ executes (at \envb{document} time), the \cmd\@biblabel\ will
+% be set to \cmd\NAT@biblabel.
+%
+% Per Karie Friedman (friedman@phys.washington.edu), multiple citations are separated by semicolons, e.g.,
+% (Jones, 1999; Abbott and Smith, 2000; Wortley, 2001a),
+% and
+% multiple citations by the same author by commas, e.g.,
+% Abela et al. (1995, 1997a, 1997b).
+% The third argument of \cmd\bibpunct\ handles the former.
+%
+% The fifth argument puts a comma after the author when the year is not in parens:
+% (Lee et al., 1996).
+%
+% Incidently, this \cmd\bibpunct\ command specifies the \classname{natbib} default values.
+%
+% We define the sectioning command to use when starting the bibliography.
+%
+% We change \classname{natbib}'s \cmd\NAT@def@citea\ procedure to effect more elaborate
+% punctuation for RMP: see item 473:
+% \cmd\cite\ order punctuation: ``If possible, \cmd\textcite should put the word 'and' between two citations and before the last citation in a list of 3 or more.''
+%
+% \begin{macrocode}
+\appdef\setup@hook{%
+% \end{macrocode}
+%
+% We define the punctuation to use in the \cmd\cite\ command's production.
+%
+% \begin{macrocode}
+ \bibpunct{(%)
+ }{%(
+ )}{;}{a}{,}{,}%
+% \end{macrocode}
+%
+% We define the sectioning command to use when starting the bibliography.

+ \let\bibpreamble\@empty
+ \def\newblock{\ }%
+ \bibhang10\p@
+ \bibsep\z@
+% \end{macrocode}
+%
+% Per Mark Doyle, \cmd\cite\ is mapped to \cmd\citep\ in RMP.
+% \changes{4.1i}{2009/10/23}{(AO, 541) Defer assignment of \cs{cite} until after natbib loads}
+% \begin{macrocode}

+% \end{macro}
+% \end{macro}
+% \end{macro}

+% \end{macro}
+%
+% \begin{macro}{\footinbib@sw}
+% Footnotes in bibliography are consistent only with numbered citations,
+% and are particularly nasty under \classname{natbib}:
+% the packcage will automatically change to numbered references if
+% any \cmd\bibitem\ commands lack the optional argument.
+% Therefore, we must uninvoke it now, even if invoked by the document.
+% The same is quietly done with
+% \classname{natbib}'s \classoption{mcite} and \classoption{compress} options.
+%
+% \changes{4.1f}{2009/07/15}{(AO, 523) Add class option nomerge, to turn off new natbib 8.3 syntax}

+% \begin{macrocode}
+\def\eprint#1{eprint #1}%
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Table of Contents}
+%
+% We set up for auto-sizing of certain TOC elements.
+%
+% To do this, we override the definitions for
+% the default TOC font (\cmd\toc@@font),
+% and define
+% formatting for the needed elements (\cmd\l@\dots).
+% Finally, we activate the autosizing by
+% assigning \cmd\toc@pre\ and \cmd\toc@post.

+% One single file generates all.
+%\begin{verbatim}
+%revtex4-2.dtx
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{tex revtex4-2.dtx}}%
+% Typesetting ths file under \TeX\ itself runs the installer,
+% which generates the package files.
+%\begin{verbatim}
+%revtex4-2.cls, revtex4.ins, revtex4.drv, aps4-2.rtx,
+%aps10pt4-2.rtx, aps11pt4-2.rtx, aps12pt4-2.rtx, revsymp.sty
+%\end{verbatim}
+%
+% \subsubsection{Generated by \texttt{pdflatex revtex4-2.dtx}}%
+% Typesetting the source file under \LaTeX\
+% generates the documentation.
+%\begin{verbatim}
+%revtex4.pdf,
+%\end{verbatim}
+%
+% \subsubsection{Auxiliary}%
+% The following are auxiliary files generated
+% in the course of running \LaTeX:
+% \begin{verbatim}
+%revtex4.aux revtex4.idx revtex4.ind revtex4.log revtex4.toc
+% \end{verbatim}
+%
+% \section{Code common to all modules}%
+%
+% The following may look a bit klootchy, but we
+% want to require only one place in this file
+% where the version number is stated,
+% and we also want to ensure that the version
+% number is embedded into every generated file.
+%
+% Now we declare that
+% these files can only be used with \LaTeXe.
+% An appropriate message is displayed if
+% a different \TeX{} format is used.

+% \section{The driver module \texttt{driver}}
+%
+% This module, consisting of the present section,
+% typesets the programmer's documentation,
+% generating the \file{README-REVTEX.txt} and sample document as needed.
+%
+% Because the only uncommented-out lines of code at the beginning of
+% this file constitute the \file{driver} module itself,
+% we can simply typeset the \file{.dtx} file directly,
+% and there is thus rarely any need to
+% generate the ``driver'' {\sc docstrip} module.
+% Module delimiters are nonetheless required so that
+% this code does not find its way into the other modules.
+%
+% The \enve{document} command concludes the typesetting run.
+%
+% \begin{macrocode}
+%<*doc>
+% \end{macrocode}
+% The driver uses packages \file{ltxdoc.sty}, \file{ltxdocext.sty},
+% \file{hyperref.sty}, and whatever font package has been selected.
+% \begin{macrocode}
+\documentclass{ltxdoc}
+\RequirePackage{ltxdocext}%
+\let\url\undefined
+\RequirePackage[colorlinks=true,linkcolor=blue]{hyperref}%
+% \end{macrocode}
+% We ask for the usual indices and glossaries.
+% \begin{macrocode}
+\CodelineIndex\EnableCrossrefs % makeindex -s gind.ist revtex4
+\RecordChanges % makeindex -s gglo.ist -o revtex4.gls revtex4.glo
+% \end{macrocode}
+%
+% \subsubsection{Docstrip and info directives}
+% We use so many {\sc docstrip} modules that we set the
+% \texttt{StandardModuleDepth} counter to 1.
+% \begin{macrocode}
+\setcounter{StandardModuleDepth}{1}
+% \end{macrocode}
+% The following command retrieves the date and version information
+% from this file.

+%
+% \section{Overview}%
+% \revtex\ is a \LaTeXe\ document class, somewhat like a hybrid of
+% the standard \LaTeX\ \classname{book} and \classname{article} classes.
+%
+% Certain packages are (should be) loaded by this class in any case:
+% \classname{amssymb}, \classname{amsmath}, \classname{bm}, \classname{natbib}.
+%
+% Certain packages are automatically loaded by this class
+% when a corresponding class option has been invoked:
+%
+% \begin{tabular}{ll}
+% \textbf{\revtex\ option}&\textbf{package}\\
+% \classoption{amsfonts}&\classname{amsfonts}\\
+% \classoption{amssymb}&\classname{amssymb}\\
+% \classoption{aps}&\classname{overcite}\\
+% \end{tabular}
+%
+% Certain other packages are to be loaded by the
+% document through explicit use of \cmd\usepackage.
+% Some mentioned in the user documentation are
+% \classname{graphicx}, \classname{longtable}, \classname{hyperref},
+% and \classname{bm}.
+%
+% Certain commonly used packages are known to be incompatible with
+% \revtex, among them \classname{multicol} and \classname{cite}.
+% If such a package is found to be loaded, \revtex\ issues an error message
+% and halts the job.
+% Halting might be considered severe punishment for loading an incompatible
+% package, but if we were to proceed, an even weirder error might be encountered
+% further down the road.
+%
+% This document class implements the substyle: a set of mutually
+% exclusive class options that, in this case, allow the
+% document class to address multiple societies.
+% It also implements a sub-substyle, giving the
+% journal of the given society.
+% Any society may create a substyle;
+% this file generates one for \classoption{aps}.
+%
+% FIXME: should always load the \classname{graphicx} package. No, allow user to load whichever graphics package is desired.
+%
+% QUERY: since \classname{amsfonts} and \classname{amssymb} extend
+% syntax, why not load them in any case?
+%
+% Certain processing occurs at the endgame for reading in \revtex, thereby establishing
+% precedence for assignments to \LaTeX's (and \revtex's) parameters:
+% \begin{enumerate}
+% \item
+% Figure out which society is operative and read in the indicated \file{.rtx} file.
+% \item
+% Figure out which journal option is operative and execute the indicated journal command. This may lead to reading in a journal substyle \file{.rtx} file.
+% \item
+% Figure out which pointsize is operative and execute the indicateded pointsize command. This may lead to reading in a pointsize \file{.rtx} file.
+% \item
+% Execute all of the document's options, in the order declared within the document.
+% \item
+% Read in all required packages (like \classname{natbib}, \classname{amsfonts}, \classname{amssymb}), that were determined by class, society, and journal.
+% \item
+% The last required package, if existing, is the document's style file, the \file{.rty} file.
+% Note that the \file{.rty} file can override the assignments of \revtex, society, journal, and required packages, and even load its own packages.
+% It can also, via appendations to \cmd\setup@hook, override the setup code itself.
+% \item
+% Execute all of the setup code accumulated. Such code can be queued by \revtex\ itself, by the society, by the journal, or by the pointsize.
+% \item
+% At this point, \revtex\ has completed the process of inputting itself,
+% and \LaTeX\ will now execute the \cmd\AtEndOfClass\ procedures.
+% \end{enumerate}
+%
+% \revtex\ will have enqueued code to execute at \cmd\AtBeginDocument\ time,
+% in two different queues.
+% \cmd\document@inithook\ executes immediately upon encountering the \cmd\begin\env{document} statement,
+% \cmd\class@documenthook\ at the end of all the code enqueued via \cmd\AtBeginDocument.
+% \begin{enumerate}
+% \item
+% Install procedures to execute at the very end of the class's
+% \cmd\AtBeginDocument\ processing, such as
+% \begin{enumerate}
+% \item
+% closing out the page grid
+% \item
+% putting out the LastPage label.
+% \item
+% issuing a \cmd\bibliographystyle\ command, based on the value set
+% by the society substyle.
+% \item
+% setting default values for parameters used in the document.
+%FIXME: differentiate between class's parameters that can wait until
+% they are used in the document, and parameters that are used at \cmd\AtBeginDocument\ time.
+% \end{enumerate}
+% \item
+% Install procedures to execute the very last at \cmd\AtEndDocument\ time,
+% such as the \cmd\clearpage\ processing.
+% \end{enumerate}
+%
+% Certain events are optionally scheduled for \cmd\AtBeginDocument\ time:
+% \begin{enumerate}
+% \item
+% Setting default values for the Booleans and for other procedures used in formatting.
+% \item
+% In response to class options options, adjusting parameters and procedures used in formatting.
+% \item
+% Implementing the \classoption{eqsecnum} option, if required.
+% \item
+% Setting the state engine for data commands.
+% \item
+% Memorizing procedures for later use.
+% \item
+% Setting type size and area, for use by later calculations.
+% \end{enumerate}
+%
+% Certain events are scheduled for \cmd\class@enddocumenthook\ time:
+% \begin{enumerate}
+% \item
+% Print out the migrated floats or the end notes, if needed.
+% \item
+% Close out the page grid.
+% \item
+% Label the last page of the document
+% \item
+% (\classname{natbib}) prepare to read in the \file{.aux} file.
+% \end{enumerate}
+%
+% \section{Writing journal-specifc extensions to \revtex}
+%
+% With this version of \revtex, we introduce a somewhat different
+% scheme for adapting \revtex\ to the needs of a specific journal.
+%
+% To create a journal substyle, you create new class options in
+% \revtex\ for the society, say \classoption{osa}, and any of that society's journals,
+% one of which is, say, \classoption{josaa},
+% using the code for the APS as a guide.
+% In particular, each of your new options should separately define \cmd\@society\
+% and \cmd\@journal. That for the former will be the same for
+% all options relating to a particular society.
+%
+% Then, for the society, you create a corresponding \file{.rtx}
+% file, in our case \file{osa.rtx}.
+% Within that file, you override procedures and parameter assignments as you see fit.
+% Ideally they will be generally applicable to all of that society's
+% journals (see the file \file{aps.rtx} for a realization of this scheme).
+% Also within that file, you include a
+% section of code for each journal, that for josaa looks like:
+% \begin{verbatim}
+% \@ifx{\@journal\journal@josaa}{%
+% <code specific to the josaa>
+% }{}%
+% \end{verbatim}
+%
+% Thus far, the scheme is similar to that used in \revtex\ 3.1.
+% However, the new scheme does differ from the old in that
+% the \file{.rtx} file should define no syntactical extensions
+% to \revtex.
+%
+% \section{The \classname{revtex4} Document Class}
+% Above, we took
+% advantage of 1) the \LaTeX\ definition of \cmd\ProvidesPackage\ and
+% 2) that the line of code immediately afterwards follows the \cmd\ProvidesClass\ statement above.

+% \section{Compatability with the geometry package}
+%
+% The \classname{geometry} package of Hideo Umeki provides a way to

+% We want to ensure that \revtex\ does not foreclose on the use of
+% this or any other such package, nor to interfere with
+% explicit assignments of such metric parameters within the
+% document preamble.
+%
+% The \LaTeX\ parameters (resp. \TeX\ primitives) set by \classname{geometry} are:
+% \cmd\paperwidth, \cmd\paperheight,
+% \cmd\textwidth, \cmd\textheight,
+% \cmd\topmargin, \cmd\headheight, \cmd\headsep,
+% \cmd\footskip, \cmd\skip\cmd\footins,

+% \cmd\columnsep,
+% \cmd\hoffset, \cmd\voffset, \cmd\mag,
+% \cmd\if@twocolumn, \cmd\if@twoside, \cmd\if@mparswitch, \cmd\if@reversemargin,
+%
+% \revtex's assignments can be overridden by
+% any package or other statement in the document preamble,
+% so it should be compatible.
+%
+%FIXME: one parameter is rendered semantically void (by \file{ltxgrid.dtx}):
+% \cmd\if@twocolumn.

+% which coincide with those of \classname{custom-bib}-generated BIBTeX styles
+% using the guard code \texttt{hypertext}.
+%
+% Note that APS has these capabilities turned off by default;
+% Loading the hyperref package turns them on.

+%
+% The default handling for a document class option depends upon whether the \cmd\@society\ is
+% defined.
+%
+% If not, then hunt for a \file{.rtx} file with that name.
+% If it exists, then we will take this option as the name of the society,
+% otherwise, declare the option as not used.
+%
+% (This behavior is similar to the \LaTeX2.09 handling, where
+% one looked for a \file{.sty} file, except that
+% in this case, we must provide for journal substyles that may be
+% defined in the society file, or have their own journal substyle file.)
+%
+% At the point where the class file is finished loading,
+% we then read in the society file.
+% That file can define further class options, such as the journal substyle.
+%
+% For users, this will mean that they can specify the society and journal simply
+% by specifying first the former and then the latter among their document class options.
+% The society \emph{must} have a corresponding \file{.rtx}.

+%
+% \subsubsection{Bibliography}
+%
+% Load Patrick Daly's \classname{natbib} package,
+% \url{ftp://ctan.tug.org/macros/latex/contrib/supported/natbib}
+%
+% Note that \classname{natbib} assumes that it loads
+% over a document class, such as the \classname{article} class,
+% that has already defined \env{thebibliography} and \cmd\@listi.
+%
+% Note also that \classname{natbib} also installs a command
+% \cmd\NAT@set@cites\ into \cmd\AtBeginDocument\ which presumes
+% that the proper \cmd\bibpunct\ command has been issued.
+%
+% Note that the macro \cmd\NAT@sort\ controls
+% whether citations are left alone (\cmd\NAT@sort=0), sorted (\cmd\NAT@sort=1), or sorted and compressed (\cmd\NAT@sort=2).
+% Since we give \classname{natbib} the \classoption{sort\&compress} option,
+% if you prefer \classoption{sort}, you need only \cmd\let \cmd\NAT@sort\ to be \cmd\@ne.
+% However, if you prefer the effect of having neither \classoption{sort} nor \classoption{sort\&compress},
+% you must \cmd\let \cmd\NAT@sort\ to be \cmd\z@ and you must also define
+% \cmd\let\cmd\NAT@cmprs\ to be \cmd\z@.
+%
+% As of version 8.2, \classname{natbib} now no longer binds at the point where it is read in.
+% This means that we can freely change \cmd\NAT@sort, \cmd\NAT@cmprs, and the new
+% \cmd\NAT@merge. Henceforth, we require that this later version be used.
+%
+% For other \classname{natbib} customizations, you may proceed as if you were going to use
+% the \file{natbib.cfg} file: anything that you can modify by this means is fair game.
+% Once \revtex\ is finished loading, you can assert any definitions for \classname{natbib} that you wish.

+% \cmd\rev@citet\ that of \cmd\textcite.
+%
+% In each case, we invoke \cmd\rtx@swap@citea\ to effect different productions between
+% multiple arguments to the \cmd\cite\ command.
+%
+% \cmd\rev@citealpnum\ provides textual citations where superscript citations are the default.

+% The procedures |\rtx@def@citea|, |\rtx@def@citea@close|, and |\rtx@def@citea@box|

+%
+% \changes{4.1j}{2009/10/25}{(AO, 552) Repair spacing in \cs{onlinecite}}
+% In these procedures, we use \cmd\count@\ to count the number of arguments of the \cmd\cite\ command,
+% and we use \cmd\c@NAT@ctr\ to keep track of which argument we are processing.
+% The latter counter is created by \classname{natbib} and used there solely in bibliography processing,
+% where it keeps track of the reference number.
+% We take over its use in these macros, but only locally; therefore these procedures should work properly, even within the bibliography.
+%FIXME: check whether this is true!
+%
+% Because we are using a scratch counter \cmd\count@, we are vulnerable to other \TeX\ programmers
+% who patch in to \classname{natbib}'s processing and who might use that counter at the same time we are doing so.
+% This is a potential source of trouble for us.
+%FIXME: store the value of \cmd\count@\ in a private \cmd\csname!
+%
+% Note that \cmd\rtx@def@citea\ begins the same as \cmd\NAT@def@citea, which it replaces,
+% then makes further decisions based on the values of the counters.
+%
+% Note also that, in \classname{natbib}, the replacement part of \cmd\NAT@def@citea@close\ could be rewritten as
+% \cmd\NAT@def@citea\cmd\prepdef\cmd\@citea\verb+{+\cmd\NAT@@close\verb+}+, which
+% would them obviate the need for us to override its meaning.
+%
+% Note, too, the effect of \cmd\rtx@def@citea@box, which replaces \cmd\NAT@def@citea@box,
+% is almost the same as the latter, except the entire \cmd\@citea\ is given as the argument
+% of \cmd\NAT@mbox.

+% We wish to extend \classname{natbib} to move spaces and citations around
+% a superscript-style citation, imitating Donald Arseneau's \classname{cite} package
+% with the \classoption{super}.
+%
+% The \cmd\rtx@@citetp\ procedure is substituted for \cmd\NAT@@citetp;
+% it then calls the \cmd\rtx@citex\ procedure and implements the features of the
+% \classoption{citeautoscript} class option.
+% In the end, \cmd\@citex\ is called with its customary parameters.
+%
+% The document should be marked up as if citations were \emph{not} superscripted,
+% and then if you select a journal substyle that has superscripted citations, \revtex\ will do its best
+% to alter the formatting of the \cmd\cite s to accomodate superscript style.
+%
+% Only citations set as superscript are affected by this procedure,
+% because we check \cmd\@cite\ against \cmd\NAT@citesuper.
+%
+% Here's a subtle point: when is the argument of \cmd\super@cite@swap\ not the same as the token \cmd\@let@token?
+% Answer: when the latter is \cmd\@sptoken! This case has to be handled separately.
+%
+% Note that whether a punctuation is movable is determined by the definition
+% of a particular control sequence name.
+% A society or journal can alter things: to remove a character from the set,
+% do, say, \cmd\expandafter \cmd\let \cmd\csname \texttt{rtx@automove;} \cmd\endcsname \cmd\relax.
+% To add a character to the set, do, say, \cmd\expandafter \cmd\let \cmd\csname \texttt{rtx@automove;} \cmd\endcsname \cmd\@empty.
+%
+% Implementation note: due to a \TeX\ peculiarity, we have to check for the case
+% where \cmd\@let@token\ is a space token \emph{before} we parse forward.
+% At issue is the corner case where an end of file is at hand. If we
+% were to let \cmd\super@cite@swap\ parse forward, we would encounter a \TeX\ end-of-file
+% error. Note that the test will be true in many distinct cases:
+% the file ends, the next character is a line terminator, the next character is a space.

+% Here, we effectively split \cmd\pagenumbering\ into two halves,
+% with a default definition for \cmd\thepage
+% and an initialization of \cmd\c@page\ at \cmd\class@documenthook\ time.
+%
+% The meaning of \cmd\thepage\ can be overridden by society, journal, or
+% anywhere within the document pramble, and the counter itself will be
+% preset at the beginning of the document.
+% \begin{macrocode}

+% When setting the column grid, we have to override the procedure

+% \cmd\moveleft, \cmd\moveright, and \cmd\parshape.
+%
+% It is one of the stranger features of \TeX\ that these two separate
+% mechanisms exist. The latter three have the effect of adding things to the
+% Main Vertical List that cannot be removed and later added back with all their
+% properties intact.
+%
+% In detail, \cmd\moveleft, say, adds a box to the MVL with
+% its reference point shifted horizontally by some amount relative to the
+% reference point of the enclosing list. If that box is removed from the
+% MVL (via a \cmd\lastbox\ operation in the output routine), and later
+% thrown back to the MVL, the shift of the box will have been ``forgotten'' by \TeX.

+% \section{Patches for lineno.sty}
+%
+% The \classname{lineno} package detects the case where the package has been loaded
+% and the document invokes \cmd\linelabel, but the \cmd\linenumbers\ command has not been
+% issued: it treats this case as an error.
+%
+% It is wrong for validity of document syntax to be dependent upon package semantics:
+% we make the condition a warning rather than an error.
+%
+% \begin{macrocode}
+\def\@LN@LLerror@org{%
+ \PackageError{lineno}{%
+ \string\linelabel\space without \string\linenumbers
+ }{%
+ Just see documentation. (New feature v4.11)%
+ }%
+ \@gobble
+}%
+\def\@LN@LLerror@ltx{%
+ \PackageWarning{lineno}{%
+ To make the \string\linelabel\space command work, you must issue the \string\linenumbers\ command
+ }%
+ \@gobble
+}%
+% \end{macrocode}
+%
+% If appropriate, enable line numbering within the abstract.
+%
+% This mechanism applies generally:
+% Create the box in a context in which the meaning of \cmd\par\ has been patched by \classname{lineno},
+% then \cmd\unvbox\ the box in a context where \cmd\set@linepenalties\ has been executed, and
+% follow up with \cmd\@linenumberpar, which forces a visit to the output routine just there.
+% Note that here, we have to de-fang \cmd\@LN@parpgbrk, which would otherwise causes the appearance
+% of a box with depth -1000 points. Go figure.
+% \begin{macrocode}
+\appdef\class@documenthook{%
+ \@ifx{\@LN@LLerror\@LN@LLerror@org}{%
+ \class@info{Overriding \string\@LN@LLerror}%
+ \let\@LN@LLerror\@LN@LLerror@ltx

+ \@ifpackageloaded{lineno}{%

+ \def\prep@absbox{\set@linepenalties}%
+ \def\post@absbox{\let\@LN@parpgbrk\@empty\@linenumberpar}%
+ }%
+ }{}%
+}%
+% \end{macrocode}
+%
+% One may well ask: how to obtain line numbering within an alignment in a float?
+% This objective, along with line numbering within footnotes, would require extraordinary measures.
+% The float would have to be thrown onto the MVL in order to acquire its line numbers, but
+% that fragment of MVL would then have to be protected from being shipped out.
+% The question of how to coordinate those lines' numbers with those of lines in the MVL would
+% also require dealing with.
+%
+% \section{Endgame for the Document Class}
+%
+% We provide for a ``job macro package'' that can override
+% definitions and assignments made by the class or any other packages it loads.
+%
+% \subsection{Job Macro Package}
+% You can create a ``job macro package'' for your document
+% that will be read in automatically every time
+% your document is processed.
+% Thus, if your job is a file called \file{myarticle.tex},
+% then the file \file{myarticle.rty} will be read in
+% just the same as if you had placed a
+% \cmd\usepackage|{myarticle.rty}| statement
+% immediately following your \cmd\documentclass\ statement.
+%
+% Within your \file{.rty} file,
+% you can define and use control sequence names that use the |@| character
+% and you can override any of the definitions or assignments made
+% by the \revtex\ document class or the selected journal substyle.
+% That is, you have the power to really mess things up badly.
+%
+% If you choose to have a job macro package, you are well
+% advised to read the \LaTeX\ guide to document classes,
+% \file{clsguide.tex} or read up on the subject
+% in a book like the \LaTeX\ Companion.
+%
+% The file \file{template.rty} contains a template for
+% creating your own job macro package.
+%
+% \begin{macrocode}
+\appdef\rtx@require@packages{%
+ \InputIfFileExists{\jobname.rty}{}{}%
+}%
+% \end{macrocode}
+%
+% \subsection{Endgame Processing for the Document Class}
+%
+% The remaining steps in processing the document class involve
+% determining the needed society, journal, and pointsize from
+% the document's class options and inputting the needed files or
+% executing the indicated procedures.
+%
+% Note that the society file is expected to declare options that will
+% allow us to determine the journal involved, and the society and journal
+% themselves determine the which pointsize options are declared, along with
+% their meanings.
+%
+% Note also that required packages are read in only after the document options
+% have been processed, because the latter can affect the former.
+%
+% Finally, the setup code is executed: this is code that depends on the
+% meanings of the switches we define and on the code within the packages we load.
+%
+% Note that there are other hooks in use: \cmd\document@inithook, which is
+% executed right at the beginning of the document, and \cmd\class@documenthook,
+% which serves as a vehicle for any \cmd\AtBeginDocument\ code we might wish to
+% execute.
+%
+%FIXME: use \cmd\class@documenthook\ only for things that bear on the MVL;
+% use \cmd\document@inithook\ for all patches to procedures defined within the preamble.
+%
+% Remember that \classname{natbib} changes its state at \cmd\AtBeginDocument\ time,
+% so we have to install our own code at a later point in the processing.
+%
+% We determine the proper \cmd\@society\ by examining the document's class options.
+% \begin{macrocode}
+\@parse@class@options@society
+% \end{macrocode}
+%
+% Then, we input the society's substyle
+% (which may in turn lead to loading a journal substyle or a pointsize substyle).
+% The substyle should not assume the value of any class option:
+% instead, it should install code into \cmd\setup@hook.
+% \begin{macrocode}
+\@process@society{aps}%
+% \end{macrocode}
+%
+% Now that the society has defined the class options relating to journals,
+% and has defined \cmd\@journal@default, we can process the journal substyle.
+% We parse the options for one that sets \cmd\@journal.
+% \begin{macrocode}
+\@parse@class@options@\@journal
+% \end{macrocode}
+% And we process the journal.
+% Note that \emph{it is an error} for a society file to fail to define
+% \cmd\@journal@default.
+%
+% \begin{macrocode}
+\expandafter\@process@journal\expandafter{\@journal@default}%
+% \end{macrocode}
+%
+% Now that the society and journal have finished defining any options relating to
+% point size, we process the class options for any that set \cmd\@pointsize.
+% \begin{macrocode}
+\@parse@class@options@\@pointsize
+% \end{macrocode}
+% And we process the pointsize.
+% Note that it is an error for the society and journal to leave \cmd\@pointsize@default\
+% undefined at this point, however, the journal may have overriden the assignment of the society.
+%
+% \begin{macrocode}
+\expandafter\@process@pointsize\expandafter{\@pointsize@default}%
+% \end{macrocode}
+%
+% Next, we process the class options for once and all.
+% Doing so sets values for some of the Booleans that were introduced along with
+% the \cmd\DeclareOption\ statements above.
+%
+%CHANGE: We process the options in the order declared in the document; this
+% gives the document greater control.
+%
+% \begin{macrocode}
+\@options
+% \end{macrocode}
+%
+% Now that the class options have been processed, we can load all the
+% packages that we know need loading.
+% \begin{macrocode}
+\rtx@require@packages
+% \end{macrocode}
+%
+% At this point, the society substyle, the journal substyle, and the
+% pointsize have all been processed, along with the document class options.
+% Some of these have left things for later; we do these now.
+%
+% \begin{macro}{\setup@hook}
+%
+% This portion of the code for this class file
+% \emph{must} appear at the very end:
+% The procedure
+% \cmd\setup@hook\

+% or will patch the code of one of the required packages

+% \changes{4.0b}{1999/06/20}{AO: made aps.rtx part of revtex4.dtx}
+% The file \file{aps.rtx} is read in by the \classname{revtex4} document class
+% if \cmd\@society\ has the value \classoption{aps}.
+%
+% Here, code specific to APS journals is separated out from the \revtex\ document class.
+% (Other societies can customize \revtex\ by supplying their own \file{.rtx} file.)
+%
+% This class extension file is a model for a class extension you might write yourself.
+%
+% First, incorporate a \cmd\ProvidesFile\ command with an optional argument giving
+% the version information, e.g.,
+% \begin{verbatim}
+% \ProvidesFile{foo}[2001/09/11 v1.1 Docinfo]%
+% \end{verbatim}
+%
+% Within the society substyle, there are two things we must do as well:
+% define the default journal,
+% \begin{verbatim}
+% \def\@journal@default{pra}%
+% \end{verbatim}
+% And do likewise for the point size:
+% \begin{verbatim}
+% \def\@pointsize@default{10}%
+% \end{verbatim}
+%
+% We first define some text entities (amounting to journal abbreviations),
+% then some APS-specific initializations,
+% then code for particular APS journals.
+% In the latter case, the choice is
+% keyed off the macro \cmd\@journal.

+% The \LaTeX\ kernel definition of \cmd\@fnsymbol\ is overridden.

+%
+% \filename{fixltx2e.sty} duplicates some features of \filename{ltxgrid} and \filename{ltxutil},
+% however, so it may be incompatible with \revtex.
+% In case it is not loaded, we must provide a meaning for \cmd\TextOrMath,
+% which that package makes robust.
+% I believe that it is \cmd\@fnsymbol\ itself that ought to be robustified.

+% \CandE{nm-init,ed-au}%
+% Initials + surname (J. F. Smith)

+% \CandE{techreport-institution-par}%
+% format tech report institution like book publisher
+% \CandE{vnum-x}%
+% Journal vol, without number as `34'
+% \CandE{pub-date}%
+% Publisher with address and date in parentheses (Oxford, 1994)
+% \CandE{pre-pub}%
+% Edition, publisher, volume, chapter, pages. Note that both use guard code pre-edn.
+% \end{itemize}
+%
+% \file{apsrmp.dbj} has the following guard codes, which \file{apsrev.dbj} does not:
+% \begin{itemize}
+% \CandE{nm-rev1}%
+% Only first name reversed, initials (AGU style: Smith, J. F., H. K. Jones)
+% \CandE{dt-beg}%
+% Date after authors
+% \CandE{vnum-sp}%
+% Journal vol (num) as `34 (2)'
+% \CandE{pp-last}%
+% Pages at end, but before any notes
+% \CandE{pub-par}%
+% Publisher in parentheses
+% \CandE{school-par}%
+% School/address in parens: `(school, address)'
+% \CandE{bkedcap}%
+% `Name Editor,' as above, editor upper case
+% \CandE{and-com}%
+% Comma even with 2 authors as `Tom, and Harry'

+%
+% After this substyle is read in, we will execute the code specific to the selected
+% journal: execute the society/journal \file{.rtx} file if it exists, or
+% execute the society/journal macro (if the latter is not defined, it will \cmd\relax\ out).
+% Here we define the default journal.

+% After this society file is read in, we will process the \cmd\@pointsize-specific
+% code. Here we define the default.
+% \begin{macrocode}
+\def\@pointsize@default{10}%
+% \end{macrocode}
+%
+% Note: the convention in \revtex\ and its substyles is that
+% the substyle must not override any explicit class options
+% declared by the document.
+% This means that the various Booleans of Section~\ref{sec:options}
+% may be assigned here only if they are still undefined at this point.
+%
+% For the APS, we supply code specific to journals PRA, PRB, PRC, PRD, PRE, PRL, PRX, PRAPPLIED, PRMATERIALS, PRFLUIDS, PRAB (was PRSTAB), PRPER (was PRSTPER), and RMP.
+% At present, they are identical,
+% with the exception of PRL and RMP.
+% We also introduce a new generic physrev style now that all of the Phys. Rev. journals
+% are identical
+% In 4.2, we make the inclusion of titles in the bibliography the default
+%
+% For most all of the APS journals, the journal-dependent
+% code is relatively meager and is therefore embedded in this file.
+% However, the RMP code is sufficiently extensive that
+% splitting it out into a separate file is more convenient.

+% \changes{4.1f}{2009/07/20}{(AO, 524) Makes no sense if citations are superscript numbers and so are footnotes}
+%
+% Rule: if \cmd\place@bibnumber\ is \cmd\place@bibnumber@sup\
+% (citations are numbered and set superscript),
+% then it makes no sense for \cmd\footinbib@sw\ to be \cmd\false@sw\
+% (footnotes set in the bibliography, as endnotes).
+% If both conditions prevailed, then the document would have footnotes
+% and citations both as superscript arabic numbers, but independently numbered,
+% which would be confusing.
+%
+% Any society that provides for both superscript numbered citations as well as for
+% numbered footnotes should check for this same condition, and deal with it.
+%
+% Note: an alternative would be for footnotes to use the same sequence of footnote devices
+% that are used by the frontmatter footnotes
+% (\cmd\frontmatter@thefootnote\ instead of arabic numbers).
+%
+% In this case, we would want to refrain from resetting \cmd\c@footnote\ at the end of
+% the title page formatting.
+% We would also want to treat body footnotes identically to frontmatter footnotes:
+% the assignments in \cmd\titleblock@produce\ would persist throughout the document.
+%

+% The following commands effectively establish the style in which \cmd\cite\ commands are
+% formatted.
+% You can think of them as the second needed component for the bibliography.
+%
+% Set up for author-year citations:
+% when \cmd\NAT@set@cites\ executes (at \envb{document} time), the \cmd\@biblabel\ will
+% be set to \cmd\NAT@biblabel.
+%
+% Per Karie Friedman (friedman@phys.washington.edu), multiple citations are separated by semicolons, e.g.,
+% (Jones, 1999; Abbott and Smith, 2000; Wortley, 2001a),
+% and
+% multiple citations by the same author by commas, e.g.,
+% Abela et al. (1995, 1997a, 1997b).
+% The third argument of \cmd\bibpunct\ handles the former.
+%
+% The fifth argument puts a comma after the author when the year is not in parens:
+% (Lee et al., 1996).
+%
+% Incidently, this \cmd\bibpunct\ command specifies the \classname{natbib} default values.
+%
+% We define the sectioning command to use when starting the bibliography.
+%
+% We change \classname{natbib}'s \cmd\NAT@def@citea\ procedure to effect more elaborate
+% punctuation for RMP: see item 473:
+% \cmd\cite\ order punctuation: ``If possible, \cmd\textcite should put the word 'and' between two citations and before the last citation in a list of 3 or more.''
+%
+% \begin{macrocode}
+\appdef\setup@hook{%
+% \end{macrocode}
+%
+% We define the punctuation to use in the \cmd\cite\ command's production.

+% \begin{macro}{\footinbib@sw}
+% Footnotes in bibliography are consistent only with numbered citations,
+% and are particularly nasty under \classname{natbib}:
+% the packcage will automatically change to numbered references if
+% any \cmd\bibitem\ commands lack the optional argument.
+% Therefore, we must uninvoke it now, even if invoked by the document.
+% The same is quietly done with
+% \classname{natbib}'s \classoption{mcite} and \classoption{compress} options.

+% \subsection{Table of Contents}
+%
+% We set up for auto-sizing of certain TOC elements.
