% \noindent
% This package is used to extract the revision and file information provided
% by the \RCS\ revision control system. Support for the \LatexToHtml\
% conversion tool is provided\footnote{\LatexToHtml\ is a conversion tool
% that allows documents written in \LaTeX\  to become part of the
% World Wide Web. It's written by
% \emph{Nikos Drakos, Computer Based Learning Unit, University of Leeds.}}
% \end{abstract}
%
%\section{Introduction}
%
% To maintain different versions of a document or to keep track on the
% development of one,
% the document is kept under a revison control system like \emph{SCCS} or \RCS.
% This package assumes you are using the \RCS\ system.
% To present the version information of a document, one needs to extract it
% from some kind of text inserted by the revision control system.
% \RCS\ offers therefore the \Id\ keyword, which is expanded by the \RCS\
% \emph{check out (co)} command and contains a
% lot of useful information. This information is made available through
% this package.
%
% The information obtained from the expanded \Id\ string are
% \begin{itemize}
% \item the filename,
% \item the date and time of the last \RCS\ \emph{co} command,
% \item the revision number,
% \item name of the user who has done this action,
% \item the status, and
% \item if the file is locked, the name of the locker.
% \end{itemize}
% For each of these items a macro is defined.
% When \emph{checking out} a file, the \RCS\ keywords should be contained in
% the \emph{checked out} source.
% If the user wishes, the |\today| macro is redefined, so that it returns
% the \RCS\ date.
%
% Many thanks to Thomas M{\"u}ller, aka Howie, who made the first \TeX\ hack
% for cracking the \Id\ string\footnote{Thanks to Colin Marquardt
% |<941etcm@gwfs.stud.fh-jena.de>| testing the support of the |fancyhdr|
% option.}.
%
% If you want to read about the implementation, put a \% before
% |\Only|\-|Description| in the code marked with |<*driver>| in the file
% |rcsinfo.dtx|.
%
%\section{User Interface}
%
%\subsection{Options}
%
% Options for this package are:
%
% \begin{description}
% \item[today]
%      Set the date of |\today| to the date obtained by the \RCS\ information.
%      If the \Id\ string is not expanded (see below), the current date is
%      used.
% \item[notoday]
%      Don't use the \RCS\ date for |\today|.
% \item[fancy]
%      We use the \texttt{fancyheadings} package to fill the footline with
%      \RCS\ information: filename, revision-number, status and date.
%
%      If the \texttt{fancyheadings} package is not already loaded, it
%      will be loaded
%      by this package. To use the footnotes, put something like:\\
%      \hspace*{1em}|\pagestyle{fancyplain}|\\
%      \hspace*{1em}|\lhead[\fancyplain{}{\leftmark}]{\fancyplain{}{\thepage}}|\\
%      \hspace*{1em}|\rhead[\fancyplain{}{\thepage}]{\fancyplain{}{\rightmark}}|\\
%      in the preamble.
% \item[fancyhdr]
%      We use the \texttt{fancyhdr} package to fill the footline with
%      \RCS\ information: filename, revision-number, status and date.
%
%      If the \texttt{fancyhdr} package is not already loaded, it will be
%      loaded
%      by this package. To use the footnotes, put something like:\\
%      \hspace*{1em}|\pagestyle{fancyplain}|\\
%      \hspace*{1em}|\fancyhead[RE,LO]{\leftmark}|\\
%      \hspace*{1em}|\fancyhead[LE,RO]{\thepage}|\\
%      in the preamble.
% \item[nofancy]
%      We don't define the footline. The \texttt{fancyheadings} /
%      \texttt{fancyhdr} package is not loaded.
% \item[scrpage2]
%      Use the \texttt{scrpage2} instead of \texttt{fancyhdr}.
%      Thanks to Marcus Meyer \texttt{<marmeyer@uni-muenster.de>}
%      for submitting the patch for this option.
% \item[long]
%      If used together with \texttt{fancy} / \texttt{fancyhdr} the date
%      string is printed in the long format
%      as |\today| returns it. If \texttt{fancy} / \texttt{fancyhdr}
%      is not used, nothing.
% \item[short]
%      If used together with \texttt{fancy} / \texttt{fancyhdr} the date
%      string is printed in the short
%      format \emph{YYYY/MM/DD}.
%      If \texttt{fancy} / \texttt{fancyhdr} is not used, nothing.
% \item[datehyphen]
%      Usually the RCS file date has the format YYYY/MM/DD. Sometimes
%      it is YYYY-MM-DD. The \texttt{datehyphen} switches the package to
%      accept this date format.
% \end{description}
% If the \texttt{babel} package is used, the |\today| string is language
% dependent.
%
% The default options are: \emph{today,long}. In the configuration file
% |rcsinfo.cfg| one of fancy heading packages may be set as a default
% option too.
%
%\subsection{Commands}
%
% \subsubsection{Defining the \RCS\ information}
%
% There is only one macro to define the information:
% |\rcsInfo|\DescribeMacro{\rcsInfo}.
% Since it must collaborate with \RCS\ it has an ``unusual'' calling sequence:
% The arguments are surrouned by \$.
% The following arguments are valid:\\
% \hspace*{0.5em} \RcsInfoCmd{}\\
% \hspace*{0.5em} \RcsInfoCmd{:}\\
% \hspace*{0.5em} \RcsInfoCmd{:\blank\emph{file}\texttt{,v}\blank\emph{rev}\blank\emph{YYYY/MM/DD}\blank\emph{hh:mm:ss}\blank\emph{owner}\blank\emph{stat}\blank\emph{lock}\blank}\\
% \hspace*{0.5em} \RcsInfoCmd{:\blank\emph{file}\texttt{,v}\blank\emph{rev}\blank\emph{YYYY/MM/DD}\blank\emph{hh:mm:ss}\blank\emph{owner}\blank\emph{stat}\blank}
%
% In the first two forms, \RCS\ has not expanded the \Id\ string.
% This form will usually be used before the file is \emph{checked in}
% the first time.
%
% \emph{YYYY/MM/DD} is a date, \emph{hh:mm:ss} a time.
% Note: when you perform the \RCS\ \emph{check out} command, the \Id\ string
% is expanded by \RCS\ automatically.
%
% To take effect, |\rcsInfo| must follow the |\begin{document}|.
% If you are using multiple files for a document, you could place
% |\rcsInfo| at the
% beginning of each file, so the information from the current file is
% obtained (this is not valid, when translating with \LatexToHtml, see below).
%
% \subsubsection{Accessing the \RCS\ information}
% There are the following macros to access the information provided by \RCS.
% If \RCS\ has not expanded the \Id\ string, or no |\rcsInfo| command is given,
% default values are returned.
%
% \begin{itemize}
% \item \DescribeMacro{\rcsInfoFile} The name of the source file, without
% the \RCS\ suffix \texttt{,v}.
%        Default: \texttt{--sourcefile--}.
% \item \DescribeMacro{\rcsInfoRevision} The \RCS\ revision number, of the
%       \emph{checked out} file.
%       Default: \texttt{--revision--}.
% \item \DescribeMacro{\rcsInfoDate} The date in the form \emph{YYYY/MM/DD},
%       when the file was \emph{checked out}.
%       Default: the current date.
% \item \DescribeMacro{\rcsInfoTime} The time, when the file was
%       \emph{checked out}.
%       Default: \texttt{--time--}.
% \item \DescribeMacro{\rcsInfoOwner} The user name of the file owner.
%       Default: \texttt{--owner--}.
% \item \DescribeMacro{\rcsInfoStatus} The stautus of the file, e.g.\
%       \texttt{Exp}.
%       Default: \texttt{--status--}.
% \item \DescribeMacro{\rcsInfoLocker} If the file is locked, the user name
%       of the locker.
%       If the file is not locked: \texttt{--not-locked--}.
%       Default: \texttt{--locker--}.
% \item \DescribeMacro{\rcsInfoYear} The year \emph{YYYY} of |\rcsInfoDate|.
%       Default: the current year.
% \item \DescribeMacro{\rcsInfoMonth} The month \emph{MM} of |\rcsInfoDate|.
%       Default: the current month.
% \item \DescribeMacro{\rcsInfoDay} The day \emph{DD} of |\rcsInfoDate|.
%       Default: the current day.
% \item \DescribeMacro{\rcsInfoLongDate} The date in the form of |\today|
%       when the file was \emph{checked out}. This is language dependend.
%       Default: the current date.
% \end{itemize}
%
% \subsection{\LatexToHtml}
%
% When converting a \LaTeX\ document to \texttt{HTML} using the
% \LatexToHtml\ tool,
% it's possible to use the \RCS\ information in the \texttt{HTML} document too.
% This functionality is offered by the extension file \texttt{rcsinfo.perl}
% which should be placed into the directory \texttt{LATEX2HTML/styles}.
% For more information have a look at the documentation of \LatexToHtml.
%
% An example is given in the file \texttt{rcsinfo2html.tex}.
%
% \noindent\underline{Notes}
% \begin{itemize}
% \item Use at least version \emph{99.1 release (March 30, 1999)} of
%       \LatexToHtml.
%
% \item You should |\usepackage{html}|.
%
% \item You must run \LaTeX\ on the input file before running \LatexToHtml.
%
% \item In order to make \LatexToHtml\ read the \verb|.aux| file, you must
%       either:
%       \begin{itemize}
%       \item call \LatexToHtml\ with the option
%                  \verb|-show_section_numbers| or
%       \item include the \verb|.aux| file explicitly in your \LaTeX-source, by
%             adding the lines in the preamble:\\
%               \verb|\begin{htmlonly}|\\
%               \verb|\input{|\emph{source}\verb|.aux}|\\
%               \verb|\end{htmlonly}|\\
%           which requires \verb|\usepackage{html}|.
%       \end{itemize}
%       If you don't do so, the \verb|\rcsInfo...| commands give no value.
%
% \item If using the \LatexToHtml\ tool, only the last |\rcsInfo| takes
%       effect, e.g.~if using several input files each having the |\rcsInfo|
%       command, only the vales of the last included file are used.
%       (If this is a serious problem for you, drop me a mail).
%
% \item If the \verb|fancy| / \verb|fancyhdr| option is given to the
%       \verb|rcsinfo| package,
%       the date of the \verb|ADDRESS| at the bottom of the \texttt{HTML}
%       page is set to the \RCS\ date.
%
% \item If you would like to set your own \verb|ADDRESS| text, you should
%       define a procedure, which sets \texttt{perl} \verb|$main::ADDRESS|
%       variable in your local \texttt{.latex2html} initialization file.
%       The routine may use the \texttt{perl}
%       variables shown below. Assign a reference of this procdure to the
%       \texttt{perl}-variable
%       \verb|$rcsinfo::SetAddressProc|.
%       E.g.\ if you have a \texttt{perl} routine \verb|&my_address_field|,
%       then \\
%       \verb|$rcsinfo::SetAddressProc = &my_address_field|.
% \end{itemize}

% \section{The Implementation}
% %%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% The implementation is based on cracking the \Id\ string. To support
% \LatexToHtml\ some macro definitions are written to the |.aux| file.
% These macros are the used by \LatexToHtml\ and |rcsinfo.perl| to extract
% the \RCS\ info.
%
% What do we need, and who we are:
%    \begin{macrocode}
%<*package>
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{rcsinfo}[2005/02/20 v1.10]
%    \end{macrocode}
%
% Declare some local counters to store the \RCS\ date
%    \begin{macrocode}
\newcount\@rcsInfoDay
\newcount\@rcsInfoMonth
\newcount\@rcsInfoYear
%    \end{macrocode}
% Declare some local counters to hold some temporary information
%    \begin{macrocode}
\newcount\@rcsInfoYearTmp
\newcount\@rcsInfoMonthTmp
\newcount\@rcsInfoDayTmp
%    \end{macrocode}
%
% To memorize, that we want to set |\today| to the date obtained by the
% \RCS\ information.
%    \begin{macrocode}
\newif\if@rcsInfoToday@
%    \end{macrocode}
%
% |\today| should return the date obtained by the \RCS\ information.
%    \begin{macrocode}
\DeclareOption{today}{
  \@rcsInfoToday@true
}
%    \end{macrocode}
%
% Ok we don't want do use it.
%    \begin{macrocode}
\DeclareOption{notoday}{
  \@rcsInfoToday@false
}
%    \end{macrocode}
%
% To memorize, that we want to have the old \texttt{fancyheadings}, the new
% \texttt{fancyhdr}, or \texttt{srcpage2} footline filled with \RCS\
% information.
%    \begin{macrocode}
\newif\if@rcsInfoUseFancy@
\newif\if@rcsInfoUseFancyhdr@
\newif\if@rcsInfoUseScrpage@
%    \end{macrocode}
%
% We want to use the old \texttt{fancyheadings} or the  new \texttt{fancyhdr}
% package, and set the footline with the \RCS\ information.
% Only one option may be in effect.
%    \begin{macrocode}
\DeclareOption{fancy}{
  \@rcsInfoUseFancy@true
  \@rcsInfoUseFancyhdr@false
  \@rcsInfoUseScrpage@false
}
\DeclareOption{fancyhdr}{
  \@rcsInfoUseFancy@false
  \@rcsInfoUseFancyhdr@true
  \@rcsInfoUseScrpage@false
}
\DeclareOption{scrpage2}{
  \@rcsInfoUseFancy@false
  \@rcsInfoUseFancyhdr@false
  \@rcsInfoUseScrpage@true
}
%    \end{macrocode}
%
% Ok we don't want do use it.
%    \begin{macrocode}
\DeclareOption{nofancy}{
  \@rcsInfoUseFancy@false
  \@rcsInfoUseFancyhdr@false
  \@rcsInfoUseScrpage@false
}
%    \end{macrocode}
%
% To memorize, that we want to use the long date format.
%    \begin{macrocode}
\newif\if@rcsInfoLong@
%    \end{macrocode}
%
% We want to use the long date format.
%    \begin{macrocode}
\DeclareOption{long}{
  \@rcsInfoLong@true
}
%    \end{macrocode}
%
% Ok we don't want do use it.
%    \begin{macrocode}
\DeclareOption{short}{
  \@rcsInfoLong@false
}
%    \end{macrocode}
%
%
% To memorize, that we want to use the date format with hypens.
%    \begin{macrocode}
\newif\if@rcsInfoDateHyphen@
\DeclareOption{datehyphen}{
  \@rcsInfoDateHyphen@true
}
%    \end{macrocode}
%
% Use these default options,
%    \begin{macrocode}
\ExecuteOptions{today,long}
%    \end{macrocode}
%
% read the configuration file, to set the default fancy headings package,
%    \begin{macrocode}
\IfFileExists{rcsinfo.cfg}{\input{rcsinfo.cfg}}{}
%    \end{macrocode}
%
% and the process the user options.
%    \begin{macrocode}
\ProcessOptions
%    \end{macrocode}
% Load \texttt{fancyheadings} / \texttt{fancyhdr} if neccessary.
%    \begin{macrocode}
\if@rcsInfoUseFancy@
    \RequirePackage{fancyheadings}
\fi
\if@rcsInfoUseFancyhdr@
    \RequirePackage{fancyhdr}
\fi
\if@rcsInfoUseScrpage@
    \RequirePackage{scrpage2}
\fi
%    \end{macrocode}
%
% If no language for the |babel| package is given in the document,
% we have to redefine |\today| (otherwise the changed |\year|, |\month| and
% |\day| won't work). In this case use the english version of |\today|.
%    \begin{macrocode}
\def\today{\ifcase\month\or

  July\or August\or September\or October\or November\or December\fi
  \space\number\day, \number\year}
%    \end{macrocode}
%
% We have a problem, since the number of arguments of |\rcsInfo| vary from
% zero to seven.
% To deal with that, we use some kind ``contuinuation passing'' style of
% programming.
% |\@rcsInfoNext| contains the action to be done next.
%
% Some packages (e.g.\ the |babel|-package with the |french|-option)
% change the catcode of |:| (colon). If this happens, we have to
% undo this in order to parse the \Id\ string (which contains a colon)
% and restore its original catcode afterwards.
% This flag is used to store whether the state of the colon was changed to
% be active.
%    \begin{macrocode}
\newif\if@rcsInfoColonIsActive@
%    \end{macrocode}

%\begin{macro}{\rcsInfo}
% Extract the \RCS\ information, and give commands shown above their values.
% Check the catcode of |:| and set the flag. The restoration is done after the

\maketitle

\section{Notes}
%%%%%%%%%%%%%%%

\begin{itemize}
\item Use at least version \emph{99.1 release (March 30, 1999)} of
      \LatexToHtml.

\item You should \verb|\usepackage{html}|.

\item You must run \LaTeX\ on the input file before running \LatexToHtml.

\item In order to make \LatexToHtml\ read the \verb|.aux| file, you must
      either:
      \begin{itemize}
      \item call \LatexToHtml\ with the option
                 \verb|-show_section_numbers| or
      \item include the \verb|.aux| file explicitly in your \LaTeX-source, by
            adding the lines in the preamble:\\
                \verb|\begin{|\verb|htmlonly}|\\  % looks ulgy, but otherwise
                \verb|\input{|\emph{source}\verb|.aux}|\\
                \verb|\end{|\verb|htmlonly}|\\    % latex2html fails.
            which requires \verb|\usepackage{html}|.
      \end{itemize}
      If you don't do so, the \verb|\rcsInfo...| commands give no value.

\item If using the \LatexToHtml\ tool, only the last \verb|\rcsInfo| takes
      effect, e.g.~if using several input files each having the \verb|\rcsInfo|
      command, only the vales of the last included file are used.
      (If this is a serious problem for you, drop me a mail).

\item If the \verb|fancy| / \verb|fancyhdr| option is given to the
      \verb|rcsinfo| package,
      the date of the \verb|ADDRESS| at the bottom of the \texttt{HTML}
      page is set to the \RCS\ date.

\item If you would like to set your own \verb|ADDRESS| text, you should
      define a procedure, which sets \texttt{perl} \verb|$main::ADDRESS|
      variable in your local \texttt{.latex2html} initialization file.
      The routine may use the \texttt{perl}
      variables shown below. Assign a reference of this procdure to the
      \texttt{perl}-variable
      \verb|$rcsinfo::SetAddressProc|.
      E.g.\ if you have a \texttt{perl} routine \verb|&my_address_field|,
      then \\
      \verb|$rcsinfo::SetAddressProc = &my_address_field|.

      For example the follownig \texttt{perl}-code does the job:
\begin{verbatim}
sub my_address_field
{
 $ADDRESS = '<hr>This file was last updated on ' .
            $rcsinfo::Date  .
            '&nbsp; by ' .
            '<a href="mailto: Juergen.Vollmer@informatik-vollmer.de">' .
            'Dr. Juergen Vollmer ' .
            '&lt;Juergen.Vollmer@informatik-vollmer.de&gt;</a>';
}
$rcsinfo::SetAddressProc = \&my_address_field;
\end{verbatim}
\end{itemize}
