-% \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

-% This very cute self-reference is a common \classname{ltxdoc} idiom.
-% \begin{macrocode}

-% And that is the end of the driver for the programmer's documentation.
-% \begin{macrocode}

-%
-% \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.

-%
-% The \LaTeX\ parameters (resp. \TeX\ primitives) set by \classname{geometry} are:

-%
-% \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@citealp\ and \cmd\rev@citealpnum\ are the aliases of \cmd\onlinecite,
-% \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.
-% These should be accessible via the \cmd\citet\ command.

-%
-% \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

-%
-% 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

-% 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:

-% \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.

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

-% Because \cmd\twocolumngrid\ requires rebalancing columns at some points,

-% \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.

-%
-% 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)%
- }%

-\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}{%

-%
-% 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.

-% \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.

-% 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.
