+% This is a contributed file to the LaTeX2e system.
+% -------------------------------------------------
+%         This is a LaTeX package to prepare author/affiliation blocks
+% Installation:
+%    LaTeX this file: creates docstrip installation file authblk.ins
+%                         AND the (LaTeX2e) documentation
+%    (La)TeX authblk.ins: creates package files authblk.sty, and optionally
+%                         documentation driver authblk.drv
+%    (authblk.ins may be edited as needed)
+%     Docstrip options available:
+%        package - to produce a .sty file with the uncommented coding
+%        driver  - to produce a driver file to print the documentation
+%        209     - (with package) for package that runs under LaTeX 2.09
+%        subpack - (with package) for coding included in other packages
+%     LaTeX the unstripped version to obtain the documentation
+%     (Documentation can be produced with LaTeX2e only)

+%
+% \section{Introduction}
+% The standard \LaTeX\ syntax for entering author names and their
+% affiliations is rather limited. The standard is to have \emph{author
+% blocks} consisting of all authors from one institute grouped together.
+% However, if there are many institutes, or if the authors are ordered in
+% some other way (e.g.\ alphabetically) it is more appropriate to use a
+% footnote system. Both methods should be available for any paper since the
+% style depends more on the number of authors and affiliations and their
+% mixture.
+%
+% This package offers a syntax for entering author names and their
+% affiliations that permits both styles, and is also compatible with the
+% standard \LaTeX\ syntax. It places its results in the control sequence
+% |\@author|, which is the standard container for the author\brsl{}affiliation
+% names; in this way it can be used immediately with standard \LaTeX\
+% classes, or with packages that modify the title\brsl{}author block.
+%
+% \section{Invoking the Package}
+% The macros in this package are included in the main document
+% with the |\usepackage| command of \LaTeXe,
+% \begin{quote}
+% |\documentclass[..]{...}|\\
+% |\usepackage[|\emph{options}|]{|\texttt{\filename}|}|
+% \end{quote}
+% where the possible \emph{options} are described below in Section~\ref{opts}.
+%
+% \section{Usage}
+%
+% Authors and affiliations can be printed in author blocks, as
+% \begin{center}
+% \begin{tabular}[t]{c}
+% J. B. Smith\\Institute for Research\\Hamilton, Ontario
+% \end{tabular}\\[1ex]
+% \begin{tabular}[t]{c}
+% C. T. Appleton and P. R. Bailey\\NASA, Greenbelt, MD
+% \end{tabular}
+% \end{center}
+% or in a line with footnote markers for the affiliations, as
+% \begin{center}
+% J. B. Smith\textsuperscript{1}, C. T. Appleton\textsuperscript{2}, and
+% P. R. Bailey\textsuperscript{2}\\[1ex]
+% \textsuperscript{1}Institute for Research, Hamilton, Ontario\\
+% \textsuperscript{2}NASA, Greenbelt, MD
+% \end{center}
+%
+% \DescribeMacro{\author}
+% \DescribeMacro{\affil}
+% The user can enter the author and affiliation information in a number of
+% different manners.
+% \begin{enumerate}
+%   \item \label{ab}Standard \LaTeX, with syntax
+%     \begin{quote}
+%       |\author{|\dots|\and|\dots|\and|\dots|}|
+%     \end{quote}
+%       where each block of author(s)\brsl{}affiliation comes between the
+%       |\and| commands, containing possibly |\\| for new lines;
+%
+%   \item \label{abfn} Automatic switching between author block or footnote
+%      style, information input with a series of |\author|, |\affil|
+%      commands as
+%     \begin{quote}
+%       |\author{|\emph{author1}|}|\\
+%       |\author{|\emph{author2}|}|\\
+%       |\affil{|\emph{affil1}|}|\\
+%       |\author{|\emph{author3}|}|\\
+%       |\author{|\emph{author4}|}|\\
+%       |\affil{|\emph{affil2}|}|\\
+%       $\cdots$
+%     \end{quote}
+%     where the authors will appear all in one (possibly continued) line
+%     with automatic footnotes, and the affiliations appear in separate lines
+%     below;
+%
+%   \item \label{fn}Footnote style with manual footnote markers given as
+%       optional arguments; in this case, the |\author| and |\affil| commands
+%       can be fully separated:
+%     \begin{quote}
+%       |\author[1]{|\emph{author1}|}|\\
+%       |\author[1]{|\emph{author2}|}|\\
+%       |\author[2]{|\emph{author3}|}|\\
+%       |\author[2]{|\emph{author4}|}|\\
+%       |\affil[1]{|\emph{affil1}|}|\\
+%       |\affil[2]{|\emph{affil2}|}|\\
+%       $\cdots$
+%     \end{quote}
+% \end{enumerate}
+% Method \ref{ab} can only produce author blocks; method \ref{fn} only
+% footnotes, while \ref{abfn} can produce both. If the number of affiliations
+% is greater than \texttt{Maxaffil}, footnotes are used, otherwise author
+% blocks.
+%
+% \DescribeMacro{\authorcr}
+% With method \ref{ab}, the |\\| command is used to switch to affiliation
+% text, possibly changing the font; if the author text is to be forced to a
+% new line, use |\authorcr| instead.
+%
+% \noindent\textbf{Warning:}
+% methods \ref{abfn} and \ref{fn} can only be used \emph{after}
+% \texttt{\filename} has been loaded, since |\affil| is otherwise
+% not defined. However, a single |\author| command (method \ref{ab})
+% can appear before |\usepackage|, or even before |\documentclass|,
+% as is allowed in standard \LaTeX.
+%
+% \section{Configuration}
+%
+% Certain aspects of the author\brsl{}affiliation blocks can be controlled by
+% the user through redefinitions.
+%
+% As already \marginpar{\raggedleft\texttt{Maxaffil}}
+% mentioned, the maximum number of affiliations before automatically
+% switching from author block to footnote mode is set in the counter
+% |Maxaffil|. Redefine this with
+% \begin{quote}|\setcounter{Maxaffil}{2}|\end{quote}
+% The default is 2.
+%
+% \DescribeMacro{\Authfont}
+% \DescribeMacro{\Affilfont}
+% The author and affiliation lines can be set in different fonts, determined
+% by these macros. By default they are |\normalfont|. Redefine them with
+% |\renewcommand|, for example:
+% \begin{quote}\begin{verbatim}
+% \renewcommand\Authfont{\scshape}
+% \renewcommand\Affilfont{\itshape\small}
+% \end{verbatim}
+% \end{quote}
+%
+% \DescribeMacro{\affilsep}
+% The interline spacing between the author and affiliation lines is set by
+% the length |\affilsep|. Change this with |\setlength|, as
+% \begin{quote}|\setlength{\affilsep}{1em}|\end{quote}
+% This spacing applies to both footnote and author block modes.
+%
+% \DescribeMacro{\Authsep}
+% \DescribeMacro{\Authand}
+% \DescribeMacro{\Authands}
+% In footnote mode, one can change the texts that comes between the
+% authors' names, between two authors, and before the last author when there
+% are more than two. For example,
+% \begin{quote}\begin{verbatim}
+% \renewcommand\Authsep{, }
+% \renewcommand\Authand{ and }
+% \renewcommand\Authands{, and }
+% \end{verbatim}
+% \end{quote}
+% This example actually shows the defaults.
+%
+% \section{Options during Loading}\label{opts}
+% Some reconfigurations are provided for by means of options to the
+% |\usepackage| command. These are:
+% \begin{description}
+% \item[\ttfamily blocks]
+%   sets |Maxaffil| to $\infty$ so that the automatic selection will always be
+%   author\brsl{}affiliation blocks;
+%
+% \item[\ttfamily noblocks]
+%   sets |Maxaffil| to 0 so that the automatic selection will always be
+%   footnote mode;
+%
+% \item[\ttfamily max$n$] ($n=2,6$) sets |Maxaffil| to $n$;
+%
+% \item[\ttfamily auth-sc] sets author font to small caps;
+%
+% \item[\ttfamily auth-sc-lg] sets author font to small caps, but with size
+%     |\large|;
+%
+% \item[\ttfamily auth-lg] sets author font to normal, but in size |\large|;
+%
+% \item[\ttfamily affil-sl] sets affiliation font to slanted;
+%
+% \item[\ttfamily affil-it] sets affiliation font to italic;
+%
+% \item[\ttfamily german] changes `and' to `und' in author lists.
+% \end{description}
+%
+% \StopEventually{\PrintIndex\PrintChanges}
+%
+% \section{Options with \texttt{docstrip}}
+% The source \texttt{.dtx} file is meant to be processed with
+% \texttt{docstrip}, for which a number of options are available:
+% \begin{description}
+% \item[\ttfamily package] to produce a \texttt{.sty} package file with most
+%     comments removed;
+%
+% \item[\ttfamily subpack] (together with \texttt{package}) for coding that
+%     is to be included inside a larger package; even more comments are
+%     removed, as well as \LaTeXe{} option handling and identification;
+%
+% \item[\ttfamily 209] (together with \texttt{package}) for a style option
+%     file that will run under the older \LaTeX~2.09;
+%
+% \item[\ttfamily driver] to produce a driver \texttt{.drv} file that will
+%     print out the documentation under \LaTeXe. The documentation cannot
+%     be printed under \LaTeX~2.09.
+%
+% \end{description}
+% The source file \texttt{\filename.dtx} is itself a driver file and can
+% be processed directly by \LaTeXe.
+%
+% \section{The Coding}
+% This section presents and explains the actual coding of the macros.
+% It is nested between |%<*package>| and |%</package>|, which
+% are indicators to \texttt{docstrip} that this coding belongs to the package
+% file.
+%
+% The \texttt{docstrip} option |<subpack>| should only be called if the
+% coding is to be included as part of another package, in which case the
+% announcement text and \LaTeXe{} options are suppressed.
+%
+% An alternative version of this coding is provided for running as a
+% style file under \LaTeX~2.09. Code lines belonging to this are
+% indicated with guard |<209>|; those for LaTeXe{} only with |<!209>|.
+%
+%    \begin{macrocode}
+%<*package>
+%    \end{macrocode}
+%
+% \subsection{Basic Idea}
+%
+% In the standard \LaTeX\ classes, the authors and their affiliations are
+% input through the |\author| command, which simply stores the argument in
+% |\@author|. The text is then output by the |\maketitle| macro within a
+% |tabular| environment, as
+% \begin{quote}\begin{verbatim}
+% \begin{tabular}[t]{c}%
+%   \@author
+% \end{tabular}
+% \end{verbatim}
+% \end{quote}
+% Different blocks within the |\author| text are separated by the |\and|
+% command, defined as
+% \begin{quote}\begin{verbatim}
+% \def\and{%
+%   \end{tabular}%
+%   \hskip 1em \@plus.17fil%
+%   \begin{tabular}[t]{c}}%
+% \end{verbatim}
+% \end{quote}
+% Clearly, the definition of |\and| must be compatible with the environment
+% in which |\@author| is output.
+%
+% The \texttt{\filename} package provides a new way to enter the author and
+% affiliation data, but puts the results into |\@author|, which means it can
+% be used with the standard classes or with any class that has the author
+% information in |\@author|. Since \texttt{\filename} controls all the font
+% formatting for author and affiliation lines, |\maketitle| should not do
+% this.
+%
+% \subsection{Configurable Commands}
+%
+% All internal commands are designated with |\AB@..| to avoid name conflicts
+% with other packages. Commands that may be redefined for local configuration
+% contain no |@| and begin with an uppercase letter, like |\Authfont|.
+%
+% The following allow the author and affiliation blocks to be formatted.
+% These may be changed in the document or in packages that input (include)
+% \texttt{\filename}.
+%
+% \begin{macro}{\Authfont}
+% \begin{macro}{\Affilfont}
+% Declarations that are to be issued for the authors and affiliations are
+% defined here. Redefine these, for example, as
+% \begin{quote}\begin{verbatim}
+% \renewcommand\Authfont{\scshape}
+% \renewcommand\Affilfont{\itshape\small}
+% \end{verbatim}
+% \end{quote}
+% By default, they are the |\normalfont|.
+%    \begin{macrocode}
+\newcommand\Authfont{\normalfont}
+\newcommand\Affilfont{\normalfont}
+%<209>\@ifundefined{normalfont}{\let\normalfont\rm}{}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+%
+% \begin{macro}{\Authsep}
+% \begin{macro}{\Authand}
+% \begin{macro}{\Authands}
+% Three macros determine what comes between author names,
+%    \begin{macrocode}
+\newcommand\Authsep{, }
+%    \end{macrocode}
+% what comes between the last and second last names for more than two authors,
+%    \begin{macrocode}
+\newcommand\Authands{, and }
+%    \end{macrocode}
+% and for exactly two authors.
+%    \begin{macrocode}
+\newcommand\Authand{ and }
+%    \end{macrocode}
+% These could be language dependent.
+% \end{macro}\end{macro}\end{macro}
+%
+% \begin{macro}{\affilsep}
+% The vertical spacing between an author and affiliation line. The length
+% |\@affilsep| comes between affiliation lines and switches between
+% |\affilsep| and 0~pt as needed.
+%    \begin{macrocode}
+\newlength{\affilsep}\setlength{\affilsep}{1em}
+\newlength{\@affilsep}
+%    \end{macrocode}
+% \end{macro}
+% Also part of the local configuration is the maximum number of affiliations
+% before switching to footnote mode. Redefine this with |\setcounter|.
+%    \begin{macrocode}
+\newcounter{Maxaffil}
+\setcounter{Maxaffil}{2}
+%    \end{macrocode}
+%
+% \subsection{Package Options}
+%
+% Options are provided to select some author and affiliation fonts, and
+% certain values of |Maxaffil|, including 0 (always footnote mode) and
+% infinity (always block mode).
+%    \begin{macrocode}

+%
+% \subsection{Supporting Macros}
+%
+% First declare some counters and flags. The number of authors, affiliations,
+% and a flag to mark a new affiliation.
+%    \begin{macrocode}
+\newcounter{authors}
+\newcounter{affil}
+\newif\ifnewaffil \newaffiltrue
+%    \end{macrocode}
+%
+% \begin{macro}{\AB@authnote}
+% \begin{macro}{\AB@affilnote}
+% The formatting of the footnote markers in the author and affiliation lines.
+% The |\textsuperscript| command must be defined for 2.09 and provided for
+% earlier version of \LaTeXe\ (before 1995/06/01).
+%    \begin{macrocode}
+\newcommand\AB@authnote[1]{\textsuperscript{\normalfont#1}}
+\newcommand\AB@affilnote[1]{\textsuperscript{\normalfont#1}}
+%<209>\@ifundefined{textsuperscript}{\newcommand\textsuperscript[1]{$^{#1}$}}{}
+%<!209>\providecommand\textsuperscript[1]{$^{#1}$}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+%
+% \begin{macro}{\AB@blk@and}
+% The macro that comes between author blocks. Initially this is nothing other
+% than setting the author font, but will be set to |\and| after the first
+% invocation. Again, everything in this definition must be robust, either
+% intrinsically or with |\protect| commands. The macro |\AB@setsep|
+% sets |\@affilsep| to the author-affiliation separation.
+%    \begin{macrocode}
+\newcommand\AB@blk@and{\protect\Authfont\protect\AB@setsep}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\AB@pand}
+% The `protected' version of |\and| that is inserted in |\AB@authors| between
+% authors and affiliations; since it begins a new author block, it sets the
+% font to the author font, and the interline spacing to the
+% author\brsl{}affiliation spacing.
+%    \begin{macrocode}
+\newcommand\AB@pand{\protect\and \protect\Authfont \protect\AB@setsep}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@sep1}\begin{macro}{\@sep2}
+% The $n$th author in |\AB@authlist| is preceeded by
+% |\@sep|$n$; this is defined as empty for $n$=1 and the as the
+% two-author separation for $n$=2, to be altered later.
+%    \begin{macrocode}
+\@namedef{@sep1}{}
+\@namedef{@sep2}{\Authand}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+%
+% \begin{macro}{\AB@affilsep}
+% \begin{macro}{\AB@affilsepx}
+% What comes before the very first footnote affiliation, and before all
+% successive affiliations. These should be separate lines within some
+% tabular environment, so reset the font every time to the affiliation one.
+% (Note: |\\| is robust in \LaTeXe, but not in 2.09; adding the |\protect|
+% before |\\| does not hurt, though.)
+%    \begin{macrocode}
+\newcommand\AB@affilsep{\protect\Affilfont}
+\newcommand\AB@affilsepx{\protect\\\protect\Affilfont}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+%
+% \begin{macro}{\AB@setsep}
+% \begin{macro}{\AB@resetsep}
+% The current interline spacing within affiliations is |\@affilsep|; the
+% initial spacing (between authors and first affiliation line) is
+% |\affilsep|; switching |\@affilsep| between 0~pt and |\affilsep| is done
+% with these macros.
+%    \begin{macrocode}
+\newcommand\AB@setsep{\setlength{\@affilsep}{\affilsep}}
+\newcommand\AB@resetsep{\setlength{\@affilsep}{\z@}}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+%
+% \begin{macro}{\AB@authlist}
+% \begin{macro}{\AB@affillist}
+% \begin{macro}{\AB@authors}
+% There are three `lists' that are filled up with various commands:
+% \begin{itemize}
+%   \item |\AB@authlist| containing all the authors;
+%
+%   \item |\AB@affillist| containing all the affiliations;
+%
+%   \item |\AB@authors| ($\equiv$|\@author|) containing the input of the
+%      standard \LaTeX\ |\author| command,  a mixture of authors and
+%      affiliations, with blocks separated by |\and| commands.
+% \end{itemize}
+% |\AB@empty| is provided for testing the emptiness of |\AB@affillist|
+% later. (Do not use |\@empty|, because that is not a `long' macro.)
+%
+% Here these lists are initialized.
+%    \begin{macrocode}
+\newcommand\AB@authlist{}
+\newcommand\AB@affillist{}
+\newcommand\AB@authors{}
+\newcommand\AB@empty{}
+%    \end{macrocode}
+% \end{macro}\end{macro}\end{macro}
+%
+% \begin{macro}{\AB@author}
+% \changes{1.1}{1997 Aug 28}{Initialize to existing \cs{@author}}
+% \changes{1.1a}{1998 Jul 14}{Define \cs{@author} for 2.09}
+% The |\AB@author| macro holds the argument of the last issued |\author|
+% command, normally stored in |\@author|. Equate these now in case
+% |\author| was issued before the class and/or packages were loaded,
+% something that is allowed in standard \LaTeX. Of course, the new
+% features with |\affil| and multiple |\author| commands will not
+% function before this package is loaded.
+%
+% For \LaTeX~2.09, must provisionally define |\@author|.
+%    \begin{macrocode}
+%<209>\@ifundefined{@author}{\def\@author}{}
+\xdef\AB@author{\noexpand\AB@blk@and\@author}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{User Interfacing Commands}
+%
+% \begin{macro}{\author}
+% Three lists are maintained for authors and affiliations. In |\AB@authors|,
+% the text for the author block is stored; both |\author| and |\affil| add
+% their arguments to this list, with |\\| between author and affiliation, and
+% |\and| between the affiliation and the next author text. If one only uses
+% the |\author| command (standard \LaTeX) one must add these separators
+% explicitly in the argument.
+%
+% In addition, both |\author| and |\affil| store their arguments in
+% |\AB@authlist| and |\AB@affillist|, adding footnote marks determined either
+% automatically, or by the optional arguments.
+%
+% Finally, |\@author| will be made up either by |AB@author|, |\AB@authors|, or
+% |\AB@authlist| plus |\AB@affillist|.
+%
+% Consequently, |\author| and |\affil| are fairly complex.
+%    \begin{macrocode}
+%<209>\renewcommand\author{\@ifnextchar[%]
+%<209>  {\@Xauthor}{\@Xauthor[]}}
+%<209>\def\@Xauthor[#1]#2%
+%<!209>\renewcommand\author[2][]%
+%    \end{macrocode}
+% The flag |\ifnewaffil| is set by |\affil| to tell |\author| that a new
+% author block is beginning. This flag is set to \meta{false} at the end
+% if this macro.
+%    \begin{macrocode}
+      {\ifnewaffil\addtocounter{affil}{1}%
+       \edef\AB@thenote{\arabic{affil}}\fi
+%    \end{macrocode}
+% Argument |#1| is the optional footnote marker; if it is present, force the
+% footnote mode by setting |Maxaffil| counter to zero.
+%    \begin{macrocode}
+      \if\relax#1\relax\def\AB@note{\AB@thenote}\else\def\AB@note{#1}%
+        \setcounter{Maxaffil}{0}\fi
+%    \end{macrocode}
+% The author list in |\AB@authlist| is to have commas (|\Authsep|) between
+% the names, nothing before the first one, and `and' (|\Authands|) before the
+% last one. If only two names are present, they are separated by |\Authand|.
+% To accomplish this, place |@sep|$n$ before author $n$ which
+% is defined to be |\Authands|; at the same time, define the previous one to
+% be |\Authsep|, taking care that |\@sep1| (empty) is never redefined, and
+% that |\@sep2| (|\Authand|) is only redefined after the third author. Note
+% that at this point in the coding, the |authors| counter is not yet
+% incremented, so its value is $n-1$.
+%    \begin{macrocode}
+      \ifnum\value{authors}>1\relax
+      \@namedef{@sep\number\c@authors}{\Authsep}\fi
+      \addtocounter{authors}{1}%
+%    \end{macrocode}
+% Put the new author text in |#2| into the lists |\AB@authors| and
+% |\AB@authlist|. Because of the expansion method of getting the existing
+% contents of these lists, all commands in the arguments must be robust. For
+% this reason, make |\thanks| and |\footnote| robust (they normally are
+% fragile).
+%
+% Note that every new line inserted into |\AB@authors| must contain
+% formatting declarations, like |\Authfont| and |\Affilfont|.
+% The newline command |\\| switches to affiliation, with extra interline
+% spacing and a different font. The extra spacing is in |\@affilsep| which is
+% either zero or |\affilsep|, as set by commands |\AB@resetsep| and
+% |\AB@setsep|. The extra spacing is meant only to come between author and
+% first affiliation lines.
+%
+% The newline command should behave differently in |\AB@authlist|; the
+% |\authorcr| macro is adequate for this (new line and |\Authfont|).
+%
+% Reminder: the font declarations must be made on each new line since
+% |\@author| is normally placed within a |tabular| environment where each
+% line has local scope so all declarations and definitions apply only within
+% it.
+%    \begin{macrocode}
+      \begingroup
+          \let\protect\@unexpandable@protect \let\and\AB@pand
+          \def\thanks{\protect\thanks}\def\footnote{\protect\footnote}%

+         {\def\\{\protect\\[\@affilsep]\protect\Affilfont
+              \protect\AB@resetsep}%
+%    \end{macrocode}
+% To allow for the standard \LaTeX\ syntax with only one |\author| command
+% for everything, put the argument |#2| into |\AB@author| with the
+% appropriate preamble |\AB@blk@and|. If |\affil| is never called, this
+% will be the final content of |\@author|. Otherwise it will become
+% |\AB@authors|. Here the previous author is |\AB@au@str| is put into
+% |\AB@authors|, and then |#2| is stored for the next |\author| or |\affil|
+% call. |\AB@as| is the separator between authors in one sub-block; |\AB@las|
+% is the separator before the last author in a sub-block; this is entered by
+% |\affil| which signals the end of a sub-block of authors.
+% (This delayed entry method cannot be used for |\AB@authlist| because there
+% one needs to know the very last author, but one never knows if another
+% |\affil| command might come along.)

+      \endgroup
+%    \end{macrocode}
+% Define |\@sep|$n$ preceeding the current author to be |\Authands|, in case
+% this should turn out to be the last author. If another author comes, he
+% will redefine this (see above).
+%    \begin{macrocode}

+% For \LaTeX~2.09, we must define this \LaTeXe\ macro.
+%    \begin{macrocode}
+%<209>\def\@unexpandable@protect{\noexpand \protect \noexpand}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\authorcr}
+% In the author blocks made up with the |\author| command alone, the |\\|
+% command is used to start a new line and to switch to affiliation formatting.
+% In order to force a new line within the author line, use |\authorcr|.
+%    \begin{macrocode}
+\newcommand\authorcr{\protect\\ \protect\Authfont \protect\AB@setsep}%
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\affil}
+% The affiliation information is also written into |\AB@authors| and
+% |\AB@affillist|. The |\ifnewaffil| flag is set to inform |\author|, the
+% `blank-or-and' macro |\AB@blk@and| is set to (protected) `and', and if
+% there is an optional argument, the counter |Maxaffil| is set to zero to
+% force footnote mode.
+%    \begin{macrocode}
+%<209>\newcommand\affil{\@ifnextchar[%]
+%<209>  {\@Xaffil}{\@Xaffil[]}}

+%    \end{macrocode}
+% As for |\author|, the newline command must be highjacked and altered. For
+% |\AB@authors|, it issues a new line and declares the affiliation font. For
+% |\AB@authlist|, where each affiliation is to appear on a single line, it is
+% converted into a comma.
+%    \begin{macrocode}

+% \section{Introduction}
+% When a \LaTeX{} document is to be set in two-column mode, one can
+% add |twocolumn| as an option to |\documentstyle| (\LaTeX~2.09)
+% or to |\documentclass| (\LaTeXe), or one can use the
+% |\twocolumn| command in the text. In either case, the columns on the last
+% page, or those before a |\cleardoublepage| command, will be of unequal
+% height.  This is because \LaTeX{} views the columns as pages which are
+% just output as pairs, and it no longer knows about the left-hand column
+% when a short right-hand one is finished.
+%
+% The macros in this package solve this problem by modifying the output
+% routines in two-column mode.
+%
+% \section{Invoking the Package}
+% The macros in this package are included in the main document
+% with the |\usepackage| command of \LaTeXe,
+% \begin{quote}
+% |\documentclass[..,twocolumn,..]{...}|\\
+% |\usepackage{|\texttt{\filename}|}|
+% \end{quote}
+% There are no \LaTeXe{} options for this package.
+%
+% Alternatively, the name of the package is added as an option to the
+% |\documentstyle| command in \LaTeX~2.09 compatibility mode, as
+% \begin{quote}
+% |\documentstyle[..,twocolumn,|\texttt{\filename}|..]{...}|
+% \end{quote}
+%
+% \section{Usage}
+% Including the \texttt{\filename} package as shown above does not activate it
+% immediately. There are a number of reasons for this.
+% \begin{enumerate}
+% \item It could be that a newer (or much older) version of \LaTeX{} is
+%       being used for which the modified |\output| routines are
+%       incompatible; in this case, the new routines must be left inactive.
+%
+% \item Sometimes the modified output routine does not work well for normal
+%       pages, especially with floats (figures and tables) or footnotes.
+%
+% \end{enumerate}
+% For these reasons, it is thought better to have the modified output
+% routines left inactive, and to turn them on only when needed.
+% \DescribeMacro{\balance}
+% This is done with the command |\balance|, which should be issued
+% somewhere in the text of what would be the first column of the last page
+% without balanced columns. If it is issued too late, i.e., in the second
+% column, then a warning message is printed that balancing may not take
+% place.
+%
+% \DescribeMacro{\nobalance}
+% To turn off the balancing routines, call |\nobalance|. This might be
+% useful where there are many `last' pages, say at the end of book
+% chapters. The |\balance| command should be given for each page that
+% needs balancing, and then turned off at the end of the second column.
+%
+% It might well be that |\balance| can be left on all the time, but one
+% should check the output carefully, and turn it off if need be.
+%
+% \section{An Alternative}
+% Making multicolumn text with Mittelbach's {\tt multicol} package is
+% perhaps a better method. It balances automatically, and allows more than
+% just two columns. Never use \texttt{\filename} together with {\tt multicol}!
+%
+% \StopEventually{\PrintIndex\PrintChanges}
+%
+% \section{Options with \texttt{docstrip}}
+% The source \texttt{.dtx} file is meant to be processed with
+% \texttt{docstrip}, for which a number of options are available:
+% \begin{description}
+% \item[\tt package] to produce a \texttt{.sty} package file with most
+%     comments removed;
+% \item[\tt 209] for a package file that will also run under the older
+%     \LaTeX~2.09 and not just under the newer (mid-1994) \LaTeXe;
+% \item[\tt subpack] (together with \texttt{package}) for coding that is to
+%     be included inside a larger package; even more comments are removed,
+%     as well as \LaTeXe{} option handling and identification;
+% \item[\tt driver] to produce a driver \texttt{.drv} file that will print
+%     out the documentation under \LaTeXe; with the \texttt{209} option,
+%     a driver \texttt{.209} file is also produced, for printing the
+%     documentation under \LaTeX~2.09.
+% \end{description}
+% The source file \texttt{\filename.dtx} is itself a driver file and can
+% be processed directly by \LaTeXe.
+%
+% \section{The Coding}
+% This section presents and explains the actual coding of the macros.
+% It is nested between |%<*package>| and |%</package>|, which
+% are indicators to \texttt{docstrip} that this coding belongs to the package
+% file.
+%
+% The \texttt{docstrip} option |<subpack>| should only be called if the
+% coding is to be included as part of another package, in which case the
+% announcement text and \LaTeXe{} options are suppressed.
+%
+% An inferior version of this coding is provided for running as a
+% style file under \LaTeX~2.09. Code lines belonging to this are
+% indicated with guard |<209>|; those for LaTeXe{} only with |<!209>|.
+%
+% \subsection{Altering the Standard {\tt\bslash output} Routines}
+% The column balancing procedure here involves making changes to the
+% standard output routines in \LaTeX. I normally do not like assuming
+% anything from {\tt latex.tex} because it may have been different in
+% earlier versions, and may change again. There I try as much as possible
+% to save current definitions of internal macros and then simply add
+% revisions.
+%
+% In this case, that is not possible. I have had to take the routine
+% |\@outputdblcol| from \LaTeX{} version 2.09, (1992 March~25) as basis.
+% However, I notice that they have not changed for many versions, so that
+% maybe there is some stability here.
+%
+% The newer \LaTeXe{} version (1994 Dec.~01) also has the same definition
+% of |\@outputdblcol|, so there should be no problems of compatibility
+% here.
+%
+% In earlier versions of \texttt{\filename}, |\@outputdblcol| was changed
+% such that
+% a flag would activate the new coding if set, otherwise the old coding
+% took place. This assumes that the `old' coding is known, because I give
+% it explicitly in the new definition. This is where problems could arise
+% if |\@outputdblcol| is ever changed.
+%
+% I now do this differently. The old definition of |\@outputdblcol| is
+% stored (without knowing what it is), and the |\balance| command redefines
+% it. Without giving |\balance|, one has the default output routines as
+% though \texttt{\filename} were never selected. This gives the user the
+% chance to turn everything off if any problems should arise.
+%
+% Since the balancing act does not always work for normal pages (where the
+% two columns are full) especially when floats are involved, it is better
+% to turn it on with |\balance| only where it is needed. It may then be
+% turned off again with |\nobalance|.
+%
+% \subsection{The Principle Behind Balancing Columns}
+% Let me first explain how |\@outputdblcol| normally works. By the time it
+% is called, the accumulated text for the `page' (\TeX{} considers each
+% column to be a page at this point) is contained in the box |\@outputbox|.
+% The routine checks if this is the first column, and if so stuffs
+% |\@outputbox| into the box |\@leftcolumn|; it then toggles the
+% |\if@firstcolumn| flag. On the next call to |\@outputdblcol|, it combines
+% |\@leftcolumn| with |\@outputbox| side by side on a single page, all
+% stored in |\@outputbox|.
+%
+% For column balancing, the procedure is slightly different. If it is the
+% first column, then the height of the column (|\@colht| = |\textheight|
+% minus double-column floats and footnotes) is doubled and the contents of
+% |\@outputbox| are dumped back into the processing. The height must be
+% doubled temporarily to allow this, otherwise the |\output| routines will
+% be immediately called again. On the second column, the new routine
+% |\@BAlancecol| is called to split |\@outputbox| into two equally high
+% pieces of text, stored in |\@leftcolumn| and |\@outputbox|, which are
+% then placed side by side as usual.
+%
+% \subsection{Macro Definitions}
+% \begin{macro}{\@BAlancecol}
+% \changes{4.0}{1993 Nov 1}{Add \cmd{\vfil} after
+%      \cmd{\unvbox1} to prevent underfull vbox}
+% \changes{4.1}{1994 May 16}{New name for \cmd{\@balancecol}, to conform
+%      more with newer conventions for package programming.}
+% \changes{4.1a}{1994 Jun 22}{Use \cmd{\newcommand} instead of \cmd{\def}}
+% We begin by defining |\@BAlancecol|, the routine that splits
+% |\@outputbox| into two nearly equally high boxes, which are then stored
+% in boxes |\@leftcolumn| and |\@outputbox|. This routine is almost
+% identical with that of Knuth in the \TeX{}Book (macro |\balancecolumns|
+% on page~417). The loop keeps going until the first column is less than
+% the second in height, making 1~pt changes in the specification each time.
+%    \begin{macrocode}
+%<*package>

+   \setbox\@leftcolumn=\vbox to \@tempdima{\unvbox1\vfil}
+   \setbox\@outputbox=\vbox to \@tempdima
+     {\dimen2=\dp3\unvbox3\kern-\dimen2
+      \vfil}
+  \fi}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@BAdblcol}
+% \changes{4.1}{1994 May 16}{New name for \cmd{\@baldblcol}, to conform
+%      more with newer conventions for package programming.}
+% \changes{4.1a}{1994 Jun 22}{Use \cmd{\newcommand} instead of \cmd{\def}}
+% \changes{4.1a}{1994 Jun 22}{Use \cmd{\PackageWarningNoLine} instead of
+%              \cmd{\@@warning}}
+% Now define the revised routine |\@outputdblcol|, and name it
+% |\@BAdblcol|. In the first column, it just puts |\@outputbox| back into
+% the processing with a doubled column height (|\@colht|). In the second
+% column, it calls |\@BAlancecol| and the places the boxes |\@leftcolumn|
+% and |\@outputbox| side by side in almost the same way that the original
+% |\@outputdblcol| does. The difference is that the final vbox is made to
+% be |\@colht| high and a |\vfil| must be added below to fill up the
+% missing space. In the original, the column boxes themselves are |\@colht|
+% high, so this is not necessary. If this feature were left off, then the
+% final box would not have the correct height, something that is noticeable
+% when a footline is added at the bottom.

+%    \end{macrocode}
+% The flag |\if@BAlanceone| seems redundant, since it is always the
+% complement of |\if@firstcolumn|. However, its function is to ensure that
+% the |\balance| command, that activates |\@BAdblcol|, actually occurs
+% before the first column of text is completed. If this is not the case, if
+% |\balance| is issued too late, then the procedure cannot function. In
+% this case, |\@BAdblcol| is entered with both |\if@firstcolumn| and
+% |\if@BAlanceone| set \meta{false}, so that the call to |\@BAlancecol| is
+% suppressed and warning message is printed.

+% \changes{4.2}{1995 Nov 07}{Add revised definition for balanced mode}
+% A new version of |\cleardoublepage| is necessary when |\balance| is

+% This is a contributed file to the LaTeX2e system.
+% -------------------------------------------------
+% This is a LaTeX package to put tables and figure captions at the end of an
+%    article even though the environments appear in the text.
+% Installation:
+%    LaTeX this file: creates docstrip installation file figcaps.ins
+%                         AND the (LaTeX2e) documentation
+%    (La)TeX figcaps.ins: creates package files figcaps.sty, and optionally
+%                         documentation driver figcaps.drv
+%    (figcaps.ins may be edited as needed)
+% Docstrip options available:
+%        package - to produce a (LaTeX2e) package .sty file
+%        plates  - to include plate environments, just like figures
+%        longtab - to include longtable environment, for longtable package (2e)
+%        sublab  - to include coding for use with sublabel.sty
+%        toc     - to enable tables of contents to be used; writes to auxiliary
+%                    files .pot and pof instead of .lof and .lot
+%        driver  - to produce a driver file to print the documentation
+%        209     - (with package) for package that runs under LaTeX 2.09
+%        subpack - (with package) for coding included in other packages
+%        agu     - (with package,subpack) for inclusion in aguplus package
+%        egs     - (with package,subpack) for inclusion in egs package

+%
+% \section{Introduction}
+% Often when producing manuscripts for submission to a journal, it is
+% required that the figure captions be listed at the end on a separate
+% page, and also that tables be put at the end too. Then when the
+% manuscript is ready and camera-ready copy, or a preprint, is to be
+% generated, one has to move them all back to the proper positions in the
+% paper.
+%
+% This style alleviates this problem. The \texttt{figure} and \texttt{table}
+% environments are placed in the text as they should be for the preprint or
+% camera-ready copy, but the tables actually are printed at the end. The
+% figures are not printed at all, but their captions are listed on a
+% separate page at the end. Optionally, the figures themselves may be
+% printed at the very end. This last only makes sense if there is something
+% in the figures, i.e., they have been produced with \texttt{picture} or are
+% imported graphics.
+%
+% \section{Invoking the Package}
+% The macros in this package are included in the main document
+% with the |\usepackage| command of \LaTeXe,
+% \begin{quote}
+% |\documentclass[..]{...}|\\
+% |\usepackage[|\emph{options}|]{|\texttt{\filename}|}|
+% \end{quote}
+% where the possible \emph{options} are described below.
+%
+% Alternatively, the name of the package is added as an option to the
+% |\documentstyle| command in \LaTeX~2.09 compatibility mode, as
+% \begin{quote}
+% |\documentstyle[..|\texttt{\filename}|..]{...}|
+% \end{quote}
+%
+% It may only be used for \texttt{article}, or an article-like main class.
+% That is, for one that does not contain the |\chapter| level of
+% sectioning.
+%
+% The order in which other packages are loaded is important for certain
+% features. If my package
+% \texttt{sublabel} is included, then it must come before \thestyle.
+% Furthermore, \thestyle{} adds to the existing definition of
+% |\appendix|, so that if the author has any packages that alter this
+% definition, they must come before \thestyle. Clearly, |\appendix| may
+% not be redefined afterwards.
+%
+% \section{Using the Package}
+% \DescribeMacro{\figcapson}\DescribeMacro{\figcapsoff}
+% The macro package in \thestyle{} operates pretty much automatically.
+% The whole thing may be turned on and off with the commands |\figcapson|
+% and |\figcapsoff|. The default is \meta{on}. One might want to
+% control the placement of figures and tables with this flag rather than by
+% adding and removing the option from the |\documentclass| command.
+%
+% Alternatively, the \LaTeXe{} options \texttt{figon} and \texttt{figoff}
+% have the same effect, with \texttt{figon} being the default.
+%
+% \DescribeMacro{\printfigures}
+% The only other means of interacting with the macros is with the command
+% |\printfigures|, which, when given anywhere in the text, enables the
+% figures themselves to be output at the very end of the paper. Without
+% this, only the captions are listed. With it, both captions and figures
+% are output.
+%
+% The \LaTeXe{} option \texttt{printfigures} in |\usepackage| is
+% equivalent to issuing the command |\printfigures| in the text.
+%
+% \DescribeMacro{\figmarkon}
+% \DescribeMacro{\figmarkoff}
+% Another option is to put marginal notes into the text at the place
+% where the float environment is entered. This is useful for camera-ready
+% copy that will be cut-and-pasted together to indicate where the figures
+% and tables should appear. The commands |\figmarkon| and |\figmarkoff|
+% control this feature, with the default being \meta{off}.
+%
+% The \LaTeXe{} option \texttt{figmark} in |\usepackage| sets this
+% default to \meta{on}; in other words, it is equivalent to issuing
+% |\figmarkon| in the text.
+%
+% \DescribeMacro{\figurecapname}
+% \DescribeMacro{\tablepagename}
+% \DescribeMacro{\figurepagename}
+% The text that is written as header at the top of the special pages is
+% defined in three commands |\figurecapname|, |\tablepagename|, and
+% |\figurepagename|. They default to English text, but may be redefined to
+% other languages, or suppressed altogether, with |\renewcommand| or with
+% \LaTeXe{} options (see page~\pageref{names}).
+%
+% \section{How it Works}
+% The contents of all the \texttt{figure} and \texttt{table} environments are
+% written to auxiliary files {\tt.lof} and {\tt.lot} respectively, and then
+% these are read in again at the end of the paper. Since these auxiliary
+% files are normally used to write information for the lists of figures and
+% tables, this capability is lost. However, it is not likely that one wants
+% such lists, or even a table of contents, in a manuscript. In fact, the
+% commands |\tableofcontents|, |\listoffigures|, |\listoftables| are turned
+% off (they issue a warning message).
+%
+% If you really do need tables of contents, then see the extra features
+% below.
+%
+% \subsection{With the \texttt{longtable} Package}
+% This package may optionally be used with the \texttt{longtable} environment defined 
+% in the package of the same name. Since such tables are normally long, i.e.\ 
+% over a page, the list of tables at the back will always start a new page for 
+% each of these. 
+% 
+% For preprints, when the tables are not moved to the back (|\figcapsoff|), it 
+% makes sense to put the \texttt{longtable} environment inside the |\afterpage| 
+% command (from the \texttt{afterpage} package). However, with |\figcapson|, 
+% and the table is move, this is useless. In this case, the |\afterpage| 
+% command is deactivated. One should realize this in case it is used for other 
+% purposes.
+% 
+% \subsection{As Module to Journal-Specific Styles}
+% Although \thestyle{} is meant to be an all-purpose bibliographic style
+% \emph{package}, it may also be incorporated as a module to other
+% packages for specific journals. In this case, many of the general features may
+% be left off. This is allowed for with \texttt{docstrip} options that not
+% only leave off certain codelines, but also include extra ones. So far,
+% options exist for
+% \begin{description}
+% \item[\ttfamily egs] for \textsl{European Geophysical Society} journals.
+% \item[\ttfamily agu] for \textsl{American Geophysical Union} journals.
+% \end{description}
+%
+% Previous options \texttt{jgr} and \texttt{grl} have become obsolete due
+% to revisions in these journals; they have been replaced by the more
+% general \texttt{agu} option.
+%
+% \section{\LaTeXe{} Options}
+% Under \LaTeXe, \emph{options} may be added to the |\usepackage| command
+% that loads the package. Available options for \thestyle{} set certain
+% control flags, thus replacing the equivalent commands, or select the
+% language for the texts that are printed by |\figurecapname|,
+% |\tablepagename|, and |\figurepagename|.
+% \begin{description}
+% \item[\ttfamily figon] (default) activates the whole procedure of moving
+%     figures and tables to the back of the article, (same as
+%     |\figcapson|);
+%
+% \item[\ttfamily figoff] deactivates the whole procedure, (same as
+%     |\figcapsoff|);
+%
+% \item[\ttfamily printfigures] allows the figures themselves and not just
+%     their captions to be output at the very end, in addition to the
+%     caption page, (same as |\printfigures|); by default this is not done;
+%
+% \item[\ttfamily figmark] enables marking of figure and table environments
+%     in the text with marginal notes; (same as |\figmarkon|);
+%
+% \item[\ttfamily mylang] (default) leaves the three \texttt{name} commands
+%     as they are; however if they are not defined at all, then they are
+%     given English values; since these name commands are not standard, one
+%     cannot expect them to be set by other language adaption packages;
+%
+% \item[\ttfamily english, american, german, austrian, french, esperanto]
+%     \label{names}
+%     set the \texttt{name} commands to the translation in the
+%     corresponding language, overwriting any previous definitions;
+%
+% \item[\ttfamily blank] sets the text of |\figurecapname|,
+%     |\tablepagename|, and |\figurepagename| to nothing.
+% \end{description}
+%
+% \StopEventually{\PrintIndex\PrintChanges}
+%
+% \section{Options with \texttt{docstrip}}
+% The source \texttt{.dtx} file is meant to be processed with
+% \texttt{docstrip}, for which a number of options are available:
+% \begin{description}
+% \item[\ttfamily plates] permits \texttt{plate} and \texttt{plate*}
+%    environments to be treated just like \texttt{figure} and
+%    \texttt{figure*}; the contents are written to the same auxiliary file
+%    and the captions are mixed with those of the figures. The environments
+%    must already exist though, for with this option the coding is included
+%    to treat plates like figures, but it does not define such plate
+%    environments.
+%
+% \item[\ttfamily longtab] permits \texttt{longtable} environment from the
+%    \texttt{longtable} tools package to be treated too (\LaTeXe\ only).
+%
+% \item[\ttfamily sublab] adds coding to enable the \thestyle{} macros to
+%    function with my other option \texttt{sublabel}, which permits objects
+%    to be numbered 4{\it a}, 4{\it b}, etc. This coding may always be
+%    included, even if \texttt{sublabel} is not invoked; the converse is
+%    not true: if \texttt{sublabel} is present, then this coding must also
+%    be there, and \texttt{sublabel} must precede \thestyle{} in the list
+%    of options.
+%
+% \item[\ttfamily toc] allows auxiliary files with the extensions {\tt.pof}
+%    and {\tt.pot} so that there is no conflict with the tables of contents
+%    files. Thus |\tableofcontents|, |\listoffigures|, |\listoftables|, and
+%    possibly |\listofplates| may be used as normal.
+%
+% \item[\ttfamily package] to produce a \texttt{.sty} package file with most
+%    comments removed;
+%
+% \item[\ttfamily 209] for a style option file that will run under the older
+%     \LaTeX~2.09;
+%
+% \item[\ttfamily subpack] (together with \texttt{package}) for coding that
+%    is to be included inside a larger package; even more comments are
+%    removed, as well as \LaTeXe{} option handling and identification;
+%
+% \item[\ttfamily agu] (with \texttt{package,subpack}) for special coding
+%    for the \textsl{AGU$^{++}$} package;
+%
+% \item[\ttfamily egs] (with \texttt{package,subpack}) for special
+%    coding for the \textsl{EGS} package;
+%
+% \item[\ttfamily driver] to produce a driver \texttt{.drv} file that will
+%     print out the documentation under \LaTeXe. The documentation cannot
+%     be printed under \LaTeX~2.09.
+%
+% \end{description}
+% The source file \texttt{\filename.dtx} is itself a driver file and can
+% be processed directly by \LaTeXe.
+%
+% \section{The Coding}
+% This section presents and explains the actual coding of the macros.
+% It is nested between |%<*package>| and |%</package>|, which
+% are indicators to \texttt{docstrip} that this coding belongs to the package
+% file.
+%
+% The \texttt{docstrip} option |<subpack>| should only be called if the
+% coding is to be included as part of another package, in which case the
+% announcement text and \LaTeXe{} options are suppressed.
+%
+% An inferior version of this coding is provided for running as a
+% style file under \LaTeX~2.09. Code lines belonging to this are
+% indicated with guard |<209>|; those for LaTeXe{} only with |<!209>|.
+%
+% Now test that the main style is article-like, i.e., it has no chapters.
+% This is because the figure caption list as well as the tables page are output
+% under a |\section*|, and because of the relabelling of figures, tables,
+% equations within appendices. (Maybe someday this will be changed.)

+% \subsection{Low Level Routines --- the Tricky Bits}
+% The way in which this routine is to work is as follows: the float
+% commands |\figure|, |\table|, and optionally |\plate| are redefined so
+% that they write everything up to the corresponding |\end| command to an
+% auxiliary file. These files have extensions {\tt.lof} (for figures and
+% plates) and {\tt.lot} (for tables). The entire contents must be written
+% literally, that is as verbatim, without any expansion. The terminal
+% |\end| text must also be literal.
+%
+% The actual internal commands that will do this are called |\@vfig|,
+% |\@vsfig|, etc., where the second variant is for the starred version of
+% the float command. These must be defined in such a way that |\|, |{|,
+% and |}| are temporarily characters (catcode=12); their functionality is
+% taken over by \verb!|!, |[|, and |]|. Furthermore, the carriage return
+% |^^M| must also be made active so that it may be used as a character
+% within the template of the definitions. Its function is to separate the
+% individual lines of text. It must be active, not `other', because
+% |\set@literal| (see below) will give it a definition of |\relax|. (It
+% probably cannot be made `other' anyway because it is unprintable.)
+%
+% Switch the category codes, within a group, of course, to keep them local.
+%    \begin{macrocode}
+\begingroup
+  \catcode `|=0 \catcode `[= 1
+  \catcode`]=2 \catcode `\{=12 \catcode `\}=12
+  \catcode`\^^M=13 \catcode`\\=12 %
+%    \end{macrocode}
+% \begin{macro}{\@vfig}
+% Now define the true working commands. Take |\@vfig| as prototype for all
+% the others. Its arguement is everything up to the literal text
+% |\end{figure}|. This argument is expanded and used as argument to
+% |\writelof| with an extra line termination (|^^M|) and the text
+% |\end{figure}| added. The function |\writelof| dissects its argument into
+% individual lines (as indicated by the active |^^M|) and writes them to
+% the {\tt.lof} file, until it finds a line of text equal to |\@term|.
+% Hence, this termination command is first defined as |\end{figure}|.
+% Finally, |\@vfig| issues the \emph{command} (not the literal text)
+% |\end{figure}| in order to close the \texttt{figure} environment. This last
+% command appears in the definition as \verb!|end[figure]! because of the
+% altered category codes.

+% \changes{4.5e}{1996 Oct 17}{Zero \cmd{\parindent} generally}
+% Now define the routine to read in the {\tt.lof} auxiliary file with the
+% purpose of listing only the captions. Since the list is to be made under
+% a |\section*|, there may be trouble if |\appendix| has been called
+% already. The redefined |\section*| command may print out |\appendixname|.
+% Thus this name is set to blank if it exists.
+%
+% The |\reset@figtab| command is called to reset the figure, plate, table
+% counters to zero. This is because they are to go through their automatic
+% sequence once more as they are read in. Actually, this is not necessary,
+% since the |\caption|s were never really called in the text part. However,
+% it is better to be certain that the counters are where we expect them.
+%
+% An entry is made to the running heads and to the table of contents.
+% The \texttt{figure} environment is redefined yet again to make use of
+% |\@fcaponly|, and |\addcontentsline| is set to swallow its arguments.
+% This latter is called by the |\@caption| command and we do not want the
+% entries to be made at this point. The |\@makecaption| command must be
+% altered to a special format for the captions list.
+% Finally, the auxiliary file {\tt.lof} is input.
+%
+% For the AGU supplement, the procedure is different. Instead of ignoring
+% everything except the |\caption|, all printable text is contained in
+% a |\figbox|, which here is defined to swallow its argument. (Actually the
+% internal |\@figbox| is redefined.)
+%
+% For AGU, need to call |\noappendix| and to set |\parindent| to zero.
+% This is because the manuscript part of AGU\TeX{} redefines |\@caption|
+% so that this is no longer done there.
+%
+% Also need to zero |\parindent| for EGS. So why not do it generally?
+%
+% Note: no distinction is made between \texttt{figure} and \texttt{figure*},
+% since both environments write the unstarred variant to the auxiliary
+% file. For a list of captions, there is no need for a distinction.

+% \subsection{Complications with the Appendix}
+% The problem is that the figures etc.\ are stored to auxiliary files
+% {\tt.lof} or {\tt.lot} and then read in later at the end of the paper.
+% Thus these files must know when the |\appendix| has been given and when
+% |\section| commands have been issued (new appendices) in order to keep the
+% number labels straight. It is also necessary to reset things to their
+% previous status. The |\@addtoreset| command must be undone, something that
+% is not normally allowed for.
+%
+% The modifications here are added to the |\appendix| definition that
+% exists \emph{before} this file is read in. The |\appendix| is not
+% defined here, nor need it even include such subnumbering.
+% The following macros merely allow such subnumbering to function properly
+% under this style option.

+% \changes{3.3}{1993 Jul 23}{Add possibility of subnumbered figures and
+%                            tables in appendix}
+% \changes{4.2}{1993 Dec 21}{Add auxiliary file switch test for the appendix
+%      entries to the \texttt{pof} and \texttt{pot} files}
+% \changes{4.5}{1996 Jan 10}{Add flag to indicate appendix is on}
+% \changes{4.5h}{1997 Nov 18}{Globally \cs{let} some things be redefined}
+% The existing definition of |\appendix| is stored and the new |\appendix|
+% command is defined. It writes |\doappendix| to the auxiliary files,
+% redefines |\section| so that it puts a |\stepcounter{section}| command
+% into the auxiliary files, and executes |\doappendix|.
+% The definition of the |\section| command must be stored at a number of
+% locations: |\@section| is the original non-appendix version, while
+% |\@@section| contains any redinitions made by |\doappendix|, i.e., by the
+% original |\appendix| command.
+%
+% Both |\@section| and |\reset@figtab| are globally set to avoid a problem
+% if the appendix occurs inside an environment. This does occur with the
+% AGU |\begin{article}|\dots|\end{article}| feature.
+%
+% The flag |\ifFC@appendix| is used to test if the appendix is active when
+% the first float appears, so that when the auxiliary file is opened, the
+% |\doappendix| is written immediately to it. Previously, without this, if
+% the first figure or table appeared in the appendix, the listed captions
+% did not have appendix numbering because this command was missing in the
+% captions files.
+%

+% The last step alters |\reset@figtab| so that appendix features are
+% reset as well as the counters.
+% \end{macro}
+%
+% \begin{macro}{\doappendix}
+% \changes{4.5h}{1997 Nov 18}{Globally \cs{let} some things be redefined}
+% The |\doappendix| contains those commands that must be executed when
+% |\appendix| is given, both in the main text, and when the auxiliary files
+% are reread in. It first saves the current definitions of |\thexxx|
+% and of |\cl@section| (the list of counters that are reset when the section
+% counter is incremented).

+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@unappendix}
+% The |\@unappendix| undoes the changes made by |\doappendix|.
+% It becomes |\reset@figcaps| when |\appendix| is called.
+% It is thus invoked by |\@figurecaps|, |\@tablepage|, and |\@figurepage|.
+%    \begin{macrocode}

+%                            sublabel.sty}}
+% \begin{macro}{\sublaboff}
+% A similar problem exists if the style option \texttt{sublabel} has been
+% activated. This could mean that figures and tables are subnumbered even
+% outside of an appendix. Subnumbering here means e.g., 4{\it a}, 4{\it b},
+% etc. As for the appendix, here too the auxiliary files must know when
+% subnumbering is turned on and off. This means that these commands must be
+% written to the auxiliary files whenever issued.
+%
+% These modifications here can only be made \emph{after}
+% \texttt{sublabel.sty} has been read in, for obvious reasons.

+% \subsection{Journal-Specific Coding}
+% \changes{4.1}{1993 Oct 22}{Add extra coding for JGR, GRL, and NLINPROC}
+% \changes{4.1}{1993 Nov 20}{Add extra coding for AGU supplement}
+% \changes{4.3}{1994 May 19}{Remove obsolete JGR, GRL coding}
+% When \thestyle{} is used as a module to other main styles for specific
+% journals, there are some extra details that must be seen to.
+%
+% \begin{macro}{\figbox}
+% \changes{4.2}{1993 Nov 20}{Add for AGU supplement, to remove figures
+%     from list of figure captions}
+% \changes{4.5b}{1996 Jul 22}{Let size fit contents automatically}
+% \changes{4.5c}{1996 Jul 29}{Add starred version for no frame}
+% For the AGU supplement, figures and plates are put into a |\figbox|
+% which reserves space for them, or which can contain a real figure.
+% During the printing of the captions, this command is set to swallow
+% its argument. The normal captions-only system cannot be used for this
+% because there may be additional width commands in the |figure| environment
+% for setting the caption widths, which must be observed, i.e., read in.
+% This box takes three arguments: width, height, and contents, which
+% are centered horizontally and vertically in the box. The box is framed
+% with |\framebox| so the parameters |\fboxsep| and |\fboxrule| may
+% be used to control its appearance.
+% The starred version of this command suppresses the frame without changing
+% the |\framebox| parameters. It actually uses |\makebox| instead.
+% It is better to use |\figbox*| to remove the frame because |\framebox|
+% is also used in the marginal notes for the figures, which always should
+% have the frame.
+%
+% If the first argument (width) is left empty, the box is made to fit its
+% contents, both vertically and horizontally. If only the second argument
+% (width) is left empty, the width will be as given and the height is scaled
+% automatically. This is for use with |\epsfig| and relatives.
+%    \begin{macrocode}
+%<agu>\def\figbox{\@ifstar{\let\agubox\makebox\@figbox}
+%<agu>  {\let\agubox\framebox\@figbox}}
+%<agu>\def\@figbox#1#2#3{\hbox to \hsize{\hfil
+%<agu>  \ifx!#1!\agubox{#3}\else
+%<agu>  \agubox[#1][c]{\ifx!#2!#3\else\@tempdima#2\relax
+%<agu>  \divide\@tempdima by2\relax
+%<agu>  \advance\@tempdima by-\fboxsep \advance\@tempdima by-\fboxrule
+%<agu>  \vrule\@height\@tempdima\@depth\@tempdima\@width\z@
+%<agu>  \vbox to \z@{\vss\hbox{#3}\vss}\fi}\fi\hfil}}
+%    \end{macrocode}
+% \end{macro}
+%
+% The marking of figures and tables with marginal notes should be
+% enabled by default.
+%    \begin{macrocode}
+%<agu>\figmarktrue
+%    \end{macrocode}
+%
+% For the AGU supplement, the necessary flag is |\if@preprint|. Furthermore,
+% for AGU preprints and manuscripts, we need to turn off the |\figurewidth|
+% and |\platewidth| commands that come with the AGU-supplied macros.
+%    \begin{macrocode}
+%<agu>\if@preprint \figcapsfalse
+%<agu>  \def\figurewidth#1{\pt@width=\hsize}
+%<agu>  \def\platewidth#1{\pt@width=\hsize}
+%<agu>\fi
+%<agu>\if@draft
+%<agu>  \def\figurewidth#1{\pt@width=\hsize}
+%<agu>  \def\platewidth#1{\pt@width=\hsize}
+%<agu>\fi
+%    \end{macrocode}
+%
+% \begin{macro}{\@makefcaption}
+% \changes{4.2}{1993 Nov 20}{Redefine for AGU supplement, to print captions
+%      in two widths}
+% \changes{4.3a}{1994 Jun 6}{For AGU, set \cmd{\hsize} to avoid overfull
+%      hbox messages}
+% Now define |\@makefcaption|, the special version of |\@makecaption| for
+% the page of captions, for AGU. This is either the supplied version of
+% the macro, or a special version that prints the caption twice, in two
+% widths.
+%    \begin{macrocode}
+%<agu>\let\ori@makecap=\@makecaption
+%<agu>\def\@makefcaption#1#2{{\if@dblcap\if@camera\pt@width=\textwidth
+%<agu> \ori@makecap{#1}{#2}
+%<agu> \pt@width=\wpt@width
+%<agu> \hsize=\pt@width
+%<agu> \vskip10pt \def\label##1{}\fi\fi
+%<agu> \ori@makecap{#1}{#2}}
+%<agu>}
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\doublecaption}
+% \changes{4.2}{1993 Nov 20}{Add for AGU supplement, to enable doubled captions
+%      in two widths}
+% To enable this double caption, one must give |\doublecaption|
+% with the width of the wider caption as argument in the preamble.
+% A normal value for \textsl{AGU} journals is 35~pc.
+%    \begin{macrocode}
+%<agu>\newdimen\wpt@width
+%<agu>\newif\if@dblcap \@dblcapfalse
+%<agu>\def\doublecaption#1{\wpt@width=#1\relax\@dblcaptrue}
+%    \end{macrocode}
+% \end{macro}
+% Finally, for \emph{EGS}, the regular |\@makecaptions|
+% macro is sufficient. In that journal, all captions are flush-left to
+% begin with, so this might as well be kept for the figure captions too.
+%    \begin{macrocode}
+%<egs>\let\@makefcaption=\@makecaption
+%    \end{macrocode}
+% The whole figure caption business is activated only for |draft| mode.
+%    \begin{macrocode}
+%<egs>\if@draft\figcapstrue\else\figcapsfalse\fi
+%    \end{macrocode}
+%
+% This terminates the special coding, and thus the style file.
+%    \begin{macrocode}

+% 
+% \section{Purpose}
+% This package is called \texttt{\filename}, and it sets the text height
+% and width and the margins such that the page is almost full. It only
+% leaves a uniform margin on all four sides. 
+% 
+% To do this, it needs to know how big the full page is, whether US letter
+% size ($8\frac{1}{2} \times 11''$) or A4 ($21 \times 29.7$~cm), or some
+% other size. This is given in the parameters |\paperwidth| and
+% |\papersize| that are set by the appropriate option in the
+% |\documentclass| command.
+% 
+% The package must also know which page style is being employed. This is
+% because it must leave space for possible headers and footers, if they are
+% present. If not, it may use that space for text.
+% 
+% \section{Invoking the Package}
+% The package is called after the |\documentclass| command as e.g.,
+% \begin{quote}
+% |\documentclass[a4paper,landscape]{article}|\\
+% |\usepackage[|\emph{options}|]{|\texttt{\filename}|}|
+% \end{quote}
+% where possible options for \texttt{\filename} are
+% \begin{quote}\begin{description}
+% \item[\tt in] (default) sets the margins to one inch;
+% \item[\tt cm] sets the margins to 1.5~cm (one centimeter is really too
+%               little);
+% \item[\tt plain] (default) selects the \texttt{plain} page style, i.e.,
+%               with no headers but only a footer;
+% \item[\tt empty] for neither headers nor footers;
+% \item[\tt headings] for both header and footers;
+% \item[\tt myheadings] also for both headers and footers.
+% \end{description}\end{quote}
+% For the last 4 options, the corresponding |\pagestyle| declaration is
+% executed, so that it is not necessary to give it again. 
+% 
+% \StopEventually{\PrintIndex\PrintChanges}
+% 
+% \section{Options with \texttt{docstrip}}
+% The source \texttt{.dtx} file is meant to be processed with
+% \texttt{docstrip}, for which a number of options are available:
+% \begin{description}
+% \item[\tt package] to produce a \texttt{.sty} package file with most
+%     comments removed;
+% \item[\tt driver] to produce a driver \texttt{.drv} file that will print
+%     out the documentation under \LaTeXe. The documentation cannot be
+%     printed under \LaTeX~2.09.
+% \end{description}
+% The source file \texttt{\filename.dtx} is itself a driver file and can
+% be processed directly by \LaTeXe.
+% 
+% \section{The Coding}
+% This section presents and explains the actual coding of the macros.
+% It is nested between |%<*package>| and |%</package>|, which
+% are indicators to \texttt{docstrip} that this coding belongs to the package 
+% file.
+%
+% \begin{macro}{\FP@margin}
+% Define the options with help of the length |\FP@margin|. The options |in|
+% and |cm| select the actual margin size.
+%    \begin{macrocode}
+%<*package>
+\newlength{\FP@margin}
+\DeclareOption{in}{\setlength{\FP@margin}{1in}}
+\DeclareOption{cm}{\setlength{\FP@margin}{1.5cm}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\ifFP@plain}
+% \begin{macro}{\ifFP@empty}
+% The remaining options determine the page style, and need two flags to
+% keep track of whether headers and footers are present.
+%    \begin{macrocode}
+\newif\ifFP@plain
+\newif\ifFP@empty
+\DeclareOption{plain}{\FP@plaintrue \FP@emptyfalse
+                      \pagestyle{plain}}
+\DeclareOption{empty}{\FP@plaintrue \FP@emptytrue
+                      \pagestyle{empty}}
+\DeclareOption{headings}{\FP@plainfalse \FP@emptyfalse
+                         \pagestyle{headings}}
+\DeclareOption{myheadings}{\FP@plainfalse \FP@emptyfalse
+                           \pagestyle{myheadings}}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+% 
+% Invoke the default options and then process the requested ones. Use the
+% starred version of |\ProcessOptions| so that the options are executed
+% in the order they were specified (not defined). Thus if someone gives
+% conflicting options (like |in| and |cm|) then the last one in the list
+% counts.
+%    \begin{macrocode}
+\ExecuteOptions{in,plain}
+\ProcessOptions*
+%    \end{macrocode}
+% 
+% \begin{macro}{\headheight}
+% \begin{macro}{\headsep}
+% If there are to be no headers (for options |empty| and |plain|, which both
+% set |\ifFP@plain| to be \meta{true}), zero the appropriate parameters.
+%    \begin{macrocode}
+\ifFP@plain
+   \setlength{\headheight}{0pt}
+   \setlength{\headsep}{0pt}
+\fi
+%    \end{macrocode}
+% \end{macro}\end{macro}
+% 
+% \begin{macro}{\footskip}
+% If there are to be not footers, zero the |\footskip| parameter. This
+% occurs only for page style |empty|, for although the two |headings|
+% styles do not include a footer, they are often used in conjunction with a
+% |\thispagestyle{plain}| command for the first page of a document.
+%    \begin{macrocode}
+\ifFP@empty
+   \setlength{\footskip}{0pt}
+\fi
+%    \end{macrocode}
+% \end{macro}
+% 
+% \begin{macro}{\textwidth}
+% \begin{macro}{\oddsidemargin}
+% \begin{macro}{\evensidemargin}
+% Calculate the width of the text from |\paperwidth| and set the left and
+% right margins. Recall that \TeX{} automatically leaves a margin of $1''$.
+%    \begin{macrocode}
+\setlength{\textwidth}{\paperwidth}
+\addtolength{\textwidth}{-2\FP@margin}
+\setlength{\oddsidemargin}{\FP@margin}
+\addtolength{\oddsidemargin}{-1in}
+\setlength{\evensidemargin}{\oddsidemargin}
+%    \end{macrocode}
+% \end{macro}\end{macro}\end{macro}
+% 
+% \begin{macro}{\textheight}
+% \begin{macro}{\topmargin}
+% Calculate the height of the text from |\paperwidth|, by removing the
+% margins, headers, and footers. Set the top margin, recalling that \TeX{}
+% automatically leaves $1''$.
+%    \begin{macrocode}
+\setlength{\textheight}{\paperheight}
+\addtolength{\textheight}{-\headheight}
+\addtolength{\textheight}{-\headsep}
+\addtolength{\textheight}{-\footskip}
+\addtolength{\textheight}{-2\FP@margin}
+\setlength{\topmargin}{\FP@margin}
+\addtolength{\topmargin}{-1in}
+%</package>
+%    \end{macrocode}

+% \section{Introduction}
+% The macros in this package allow all counters to be subnumbered, as for
+% example 4{\itshape a}, 4{\itshape b}, 4{\itshape c}, simply by
+% bracketting the objects to be so numbered with appropriate on/off
+% commands. These commands specify which counters are to be subnumbered,
+% and they are of global effect. This means that they will work with any
+% user-defined counters too, and that their effect goes beyond any current
+% environment.
+% 
+% \section{Invoking the Package}
+% The macros in this package are included in the main document 
+% with the |\usepackage| command of \LaTeXe,
+% \begin{quote}
+% |\documentclass[..]{...}|\\
+% |\usepackage[|\emph{options}|]{|\texttt{\filename}|}|
+% \end{quote}
+% where the possible \emph{options} are:
+% \begin{description}
+% \item[\tt italic] to have subnumbers as italic lowercase letters
+%       (default);
+% \item[\tt roman] to have the subnumbers as Roman lowercase letters, as
+%       4{\rmfamily a}.
+% \end{description}
+%
+% Alternatively, the name of the package is added as an option to the
+% |\documentstyle| command in \LaTeX~2.09 compatibility mode, as
+% \begin{quote}
+% |\documentstyle[..|\texttt{\filename}|..]{...}|
+% \end{quote}
+% In this case, no options are possible.
+% 
+% \section{Usage}
+% \DescribeMacro{\sublabon}
+% \DescribeMacro{\sublaboff}
+% In order to number equations, figures, plates, and tables automatically
+% with subnumbers (e.g.\ 4{\itshape a}, 4{\itshape b}, 4{\itshape c}) use
+% the commands |\sublabon| and |\sublaboff|. These commands take as
+% argument the name of the counter that is to be subnumbered, i.e.
+% \texttt{equation}, \texttt{figure}, or \texttt{table}. The on and off
+% versions bracket the objects that are to be labelled with the same number
+% but different letters. For example,
+% 
+% \begin{quote}
+% \begin{verbatim}
+% \sublabon{figure}
+% \begin{figure}
+%   \caption{Text of Fig. 4a}
+% \end{figure}
+% \begin{figure}
+%   \caption{Text of Fig. 4b}
+% \end{figure}
+% \sublaboff{figure}
+% \end{verbatim}
+% \end{quote}
+% 
+% These commands also work for the |equation| environment in the same way. 
+% For the |eqnarray| environment, some care must be taken. The 
+% |\sublabon| command is to be given {\em in} the first equation to be 
+% bracketted, before the |\label| and |\\| commands, while the 
+% |\sublaboff| command is given after the |\\| of the last equation 
+% in the group. If necessary, it must come after |\end{eqnarray}|.
+% \begin{quote}
+% \begin{verbatim}
+% \begin{eqnarray}
+%   x & = & a \label{eq:x}\\%--> 1
+%   \sublabon{equation}
+%   y & = & b \label{eq:y}\\%--> 2a
+%   z & = & c \label{eq:z}\\%--> 2b
+%   \sublaboff{equation}
+%   w & = & d \label{eq:w}  %--> 3
+% \end{eqnarray}
+% \end{verbatim}
+% \end{quote}
+% 
+% If two groups appear adjacently, it is only necessary to give 
+% |\sublabon| between them.
+%
+% \DescribeMacro{\substyle}
+% The style in which the sublabels are written is determined by a command
+% |\substyle|. Its default definition is as italic lowercase
+% letters.\footnote{In \LaTeXe, if the option \texttt{roman} is added to
+% the \texttt{\bslash usepackage} command, then the default is upright
+% lowercase letters.} If
+% one wishes, this may be changed in the document itself. It must take an
+% argument that is a counter. For example, to change the style of sublabels
+% to be as 5--A, 5--B, 5--C, give
+% \begin{quote}
+% |\renewcommand{\substyle}[1]{--\Alph{#1}}|
+% \end{quote}
+% \section{Interference with Other Options}
+% If both |sublabel| and |figcaps| packages are to be used together, then 
+% |sublabel| must be input first. This is because
+% |figcaps| makes modifications so that the sublabelling also works on the page
+% of figure captions.
+%
+% Other packages (like \texttt{amsmath}) also modify some of the commands
+% redefined here. As of version~4.4, the redefinitions are delayed until 
+% after all packages are loaded, so that this conflict is avoided. For
+% earlier versions, things went wrong if \texttt{amsmath} were loaded after
+% \texttt{filename}.

+% 
+% \section{Options with \texttt{docstrip}}
+% The source \texttt{.dtx} file is meant to be processed with
+% \texttt{docstrip}, for which a number of options are available:
+% \begin{description}
+% \item[\tt package] to produce a \texttt{.sty} package file with most
+%     comments removed;
+% \item[\tt 209] for a package file that will also run under the older
+%     \LaTeX~2.09 and not just under the newer (mid-1994) \LaTeXe;
+% \item[\tt subpack] (together with \texttt{package}) for coding that is to
+%     be included inside a larger package; even more comments are removed,
+%     as well as \LaTeXe{} option handling and identification;
+% \item[\tt agu] (with \texttt{package,subpack}) for special coding for
+%     the \textsl{AGU$^{++}$} package;
+% \item[\tt driver] to produce a driver \texttt{.drv} file that will print
+%     out the documentation under \LaTeXe. The documentation cannot be
+%     printed under \LaTeX~2.09.
+% \end{description}
+% The source file \texttt{\filename.dtx} is itself a driver file and can
+% be processed directly by \LaTeXe.
+% 
+% \section{The Coding}
+% This section presents and explains the actual coding of the macros.
+% It is nested between |%<*package>| and |%</package>|, which
+% are indicators to \texttt{docstrip} that this coding belongs to the package 
+% file.
+%
+% The \texttt{docstrip} option |<subpack>| should only be called if the
+% coding is to be included as part of another package, in which case the 
+% announcement text and \LaTeXe{} options are suppressed.
+%
+% An inferior version of this coding is provided for running as a 
+% style file under \LaTeX~2.09. Code lines belonging to this are
+% indicated with guard |<209>|; those for LaTeXe{} only with |<!209>|.
+%
+% There is a problem if \texttt{\filename} is used with the package
+% \texttt{figcaps}, which makes modifications to the sublabelling
+% commands.  Thus \texttt{\filename} must be read in \emph{before}
+% \texttt{figcaps}. This is tested with the existence of the command
+% |\iffigcaps|, which should not be defined at this point.

+% \changes{4.3d}{1997 Mar 16}{Remove some superfluous lines}
+% The style of the sublabel, or subnumbering, is defined by |\substyle|.  A

+%
+% \begin{macro}{\sublabon}
+% \changes{4.3a}{1994 Jun 22}{Use \cs{newcommand}}
+% The basic principle of this macro is that when |\sublabon{|\emph{ctr}|}|
+% is called, then a new counter called |sb@|\emph{ctr} is created, if it
+% does not already exist. That is, its internal name is |\c@sb@|\emph{ctr},
+% as is standard for \LaTeX{} counters. Its value is set to $0$ and the main
+% counter \emph{ctr} is incremented. The command that formats and prints
+% out the value of the main counter, |\the|\emph{ctr} is redefined to be
+% \begin{quote}
+% |\@ldthe|\emph{ctr}|{\substyle{sb@|\emph{ctr}|}}|
+% \end{quote}
+% where |\@ldthe|\emph{ctr} is the stored definition |\the|\emph{ctr} and
+% |\substyle| is a command that operates on a counter to format it.
+%
+% First |\sublabon| tests if there really is a counter with the given
+% name.
+%    \begin{macrocode}
+\newcommand{\sublabon}[1]{\@bsphack
+\@ifundefined{c@#1}{%
+%<209>    \@latexerr
+%<!209>    \PackageError{sublabel}
+  {\protect\sublabon\space called for a non-existent counter}{\@eha}}
+%    \end{macrocode}
+% Now test for the subcounter |sb@|\emph{ctr} and if it does not exist,
+% create it and set its value to $-1$.
+%    \begin{macrocode}
+ {\@ifundefined{c@sb@#1}{\expandafter\newcount\csname c@sb@#1\endcsname
+  \setcounter{sb@#1}{-1}}{}%
+%    \end{macrocode}
+% The value $-1$ means that the subcounter has not yet been used. This
+% value is set on creation, or by |\sublaboff| if the subcounter was never
+% stepped. This is the trick that allows multiple calls to |\sublabon|
+% without intervening |\sublaboff| calls. We have to avoid calling
+% |\sublaboff| when there was no stepping. Call it only if the current
+% value of the subcounter is 0 or more.
+%    \begin{macrocode}
+\ifnum\@nameuse{c@sb@#1}<0\else\sublaboff{#1}\fi
+%    \end{macrocode}
+% Set the counters \emph{ctr} and |sb@|\emph{ctr}.
+%    \begin{macrocode}
+\stepcounter{#1}%
+\setcounter{sb@#1}{0}%
+%    \end{macrocode}
+% A correction must be made for the |eqnarray| environment which
+% increments the |equation| counter immediately on entry and then after
+% each equation. That is, the |equation| counter already holds the value of
+% the \emph{next} equation. Thus we must set the two counters to the
+% values that they should have for the next equation. For example, let us
+% suppose the following:
+% \begin{quote}
+% We are outside the |eqnarray| environment, the last equation was
+% number~3, so the |equation| counter has the value |3|.
+% 
+% We enter |eqnarray|; the |equation| counter is incremented immediately to
+% |4|.
+% 
+% We write an equation; it obtains the number~4, and |equation| goes to
+% |5|.
+% 
+% We call |\sublabon{equation}|, and |equation| is set to |6| and
+% |sb@equation| to |0| (so far). Since the counter is stepped only 
+% \emph{after} the equation in this environment, this would mean that the next
+% equation would be numbered 6-0 instead of the desired 5-1. 
+% 
+% Hence the correction: decrement |equation| and set |sb@equation| to 1.
+% \end{quote}
+%    \begin{macrocode}
+\def\@tempa{eqnarray}\ifx \@tempa\@currenvir 
+    \addtocounter{equation}{-1}\setcounter{sb@equation}{1}\fi
+%    \end{macrocode}
+% Note that the above does not test if |#1| really is |equation|. However,
+% if |\sublabon| is used within |eqnarray|, then it only makes sense to
+% subnumber equations.
+%
+%  Now save the definition of |\the|\emph{ctr} as |\@ldthe|\emph{ctr}.
+%  (This combination of |\expandafter| is necessary. I have experimented
+%    with many other variations.)
+%    \begin{macrocode}
+\global\expandafter\let\csname @ldthe#1\expandafter\endcsname
+    \csname the#1\endcsname
+%    \end{macrocode}
+% and redefine |\the|\emph{ctr} to add |\substyle| with the subcounter.
+%    \begin{macrocode}
+\expandafter\gdef\csname the#1\endcsname{%
+   \@nameuse{@ldthe#1}{\substyle{sb@#1}}}
+}\@esphack}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\sublaboff}
+% \changes{4.3a}{1994 Jun 22}{Use \cs{newcommand}}
+% The command that turns off the sublabelling tests if there is such a
+% counter, and if there exists a subcounter for it. If both tests pass,
+% then it checks that the subcounter has a non-negative value, for if it
+% does not, then there was no corresponding |\sublabon| command. That is,
+% the on/off commands are not nested properly. These tests are necessary to
+% check for typing errors.
+%    \begin{macrocode}
+\newcommand{\sublaboff}[1]{\@bsphack
+\@ifundefined{c@#1}{%
+%<209>    \@latexerr
+%<!209>    \PackageError{sublabel}
+  {\protect\sublaboff\space called for a non-existent counter}{\@eha}}
+ {\@ifundefined{c@sb@#1}{%
+%<209>    \@warning

+ {\protect\sublaboff{#1} called without any previous

+%    \end{macrocode}
+% However, if the subcounter has a 0 value, then |\sublabon| was indeed
+% called, but the counter was never stepped with |\stepcounter|. This is
+% not an error, but it means that the old value of \emph{ctr} should be
+% restored. The subcounter is set to $-1$ to indicate this to the next
+% call to |\sublabon|. The numbering goes on as if |\sublabon| and 
+% |\sublaboff| had never been given.
+%    \begin{macrocode}
+\ifnum\@nameuse{c@sb@#1}=0\addtocounter{#1}{-1}\fi

+% then the |equation| counter must be corrected again, to hold the number

+% A very important matter has still to be done: redefine |\stepcounter| so
+% that it increments the subcounter and not the main one. It is not
+% necessary to redefine |\refstepcounter| since it calls |\stepcounter|
+% itself. The existing definition of |\stepcounter| is saved and used in
+% the new definition.
+%
+% This is done at the start of the document, not immediately, in case some
+% other package is loaded that alters |\setcounter|. This also applies to 
+% |\addtocounter| and |\endeqnarray|. For example, the \texttt{amsmath}
+% package makes such changes, so if it is loaded after \texttt{\filename}
+% it clobbers these new definitions if they are not delayed. (This used to

+% A similar refinement must be done to |\addtocounter| to allow for any
+% macros that fiddle with counters. (The \texttt{planotable} environment of
+% the AGU styles does this, for example.) If the fiddling is done
+% explicitly (by giving |\c@|\emph{ctr} a new value) then we are lost.

+% Lastly, the |eqnarray| environment itself must be altered to allow for

+% environment.) The normal |\endeqnarray| command explicitly decrements the
+% |equation| counter (not with |\stepcounter|) so that it now points to the
+% last equation, as usual. However if the subnumbering is on at this point,
+% the |equation| must be re-incremented and |sb@equation| decremented
+% instead.
