+% \maketitle
+%
+% \begin{abstract}
+% The package provides additional rerun warnings if some
+% auxiliary files have changed. It is based on MD5 checksum,
+% provided by \pdfTeX.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% \LaTeX\ informs the user, when to run \LaTeX\ again, if the
+% references have changed. It has the old references from the
+% first reading of the \xext{aux} files already in memory, thus
+% it compares them with the new version of the \xext{aux} file
+% at the end of the document. However this rerun warnings are
+% not given for the table of contents and other data stored
+% in the \xext{aux} files or other auxiliary files.
+% Usually many of these data as the table of contents is not keep
+% in memory. If someone wants to detect changes, he has either
+% to keep the data in memory. This does not scale well with huge
+% documents. Or he copies the file before they are changed. Slow
+% I/O operations cost time.
+%
+% Since version 1.30.0 \pdfTeX\ provides \cs{pdfmdfivesum}
+% and \cs{pdffilesize}.
+% These features are also available in \LuaTeX, provided by package
+% \xpackage{pdftexcmds}.
+% Thus this package \xpackage{rerunfilecheck} uses these features to
+% detect file changes. This saves the packages from keeping
+% the whole files in memory or in file copies.
+% The drawback are different files with the same size and the
+% same MD5 checksum (seldom, hopefully).
+%
+% \subsection{Options}
+%
+% All options are key value options of boolean type.
+% No option or |true| turns an option on, |false| disables
+% an option.
+% \begin{description}
+% \item[\xoption{mainaux}:]
+%   Check the main \xext{aux} file.
+% \item[\xoption{partaux}:]
+%   Check the \xext{aux} files from \cs{include} files.
+% \item[\xoption{starttoc}:]
+%   Add the rerun checks in \cs{@starttoc} that is called by
+%   \cs{tableofcontents}, \cs{listoffigures}, \dots
+% \item[\xoption{index}, \xoption{glossary}:]
+%   \LaTeX's original \cs{makeindex} and \cs{makeglossary} are
+%   redefined to add the rerun checks. The options do not have
+%   an effect, if \cs{makeindex}/\cs{makeglossary} are already
+%   called or if a package or class had redefined or will
+%   redefine them.
+% \item[\xoption{aux}:]
+%   This option turns all previous options on or off.
+%   ``aux'' means auxiliary file.
+% \end{description}
+% The default for the options is |false|, because
+% some internals must be redefined to insert the
+% rerun checks.
+% The options can be set in \cs{usepackage} or
+% the configuration file \xfile{rerunfilecheck.cfg}.
+% Global options are ignored (since 1.4).
+%
+% \begin{declcs}{RerunFileCheckSetup} \M{key value list}
+% \end{declcs}
+% Options can also be set using \cs{RerunFileCheckSetup}.
+% Currently all options are disabled after the package
+% is loaded. Thus \cs{RerunFileCheckSetup} makes sense in
+% the configuration file only.
+%
+% Example for the configuration file:
+%    \begin{macrocode}
+%<*cfg>
+\ProvidesFile{rerunfilecheck.cfg}[2019/12/05 Default configuration]%
+\RerunFileCheckSetup{aux}
+%</cfg>
+%    \end{macrocode}
+%
+% \subsection{Interface for class/package authors}
+%
+% \begin{declcs}{RerunFileCheck} \M{file} \M{file closing action} \M{rerun warning}
+% \end{declcs}
+% If you want to add a rerun check, call \cs{RerunFileCheck} right before
+% an output file is opened for writing. The macro first remembers
+% the current checksum of \meta{file}.
+% The file is checked again right before the end of the job.
+% Macro \cs{AtVeryEndDocument} of package \xpackage{atveryend}
+% is used to place the check after the main aux file is closed
+% in |\end{document}|. Before reading the file again, it must be
+% closed. Provide the code for closing in argument \meta{file closing action}.
+% Do not forget \cs{immediate} before \cs{openout}. Otherwise the
+% closing action would be delayed to the next shipout that never happens
+% (the last page is already shipped out).
+% If the file has changed, \cs{RerunFileCheck} informs the user with
+% a warning that the file has changed and says the magic word ``Rerun''.
+% If the last argument \meta{rerun warning} is not empty, then
+% the rerun sentence is replaced by it. Usually the phrase
+% ``to get something right'' is added.
+% As example the relevant part of the redefined \cs{makeindex}
+% is shown, see package code:
+%\begin{quote}
+%\begin{verbatim}
+%\newwrite\@indexfile
+%\RerunFileCheck{\jobname.idx}{%
+%  \immediate\closeout\@indexfile
+%}{%
+%  Rerun LaTeX/makeindex to get index right%
+%}%
+%\immediate\openout\@indexfile=\jobname.idx %
+%\end{verbatim}
+%\end{quote}

+%% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{rerunfilecheck}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/rerunfilecheck/rerunfilecheck.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/rerunfilecheck/rerunfilecheck.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `rerunfilecheck'
+% are also available in a TDS compliant ZIP archive. There
+% the packages are already unpacked and the documentation files
+% are generated. The files and directories obey the TDS standard.
+% \begin{description}
+% \item[\CTANinstall{install/macros/latex/contrib/rerunfilecheck.tds.zip}]
+% \end{description}
+% \emph{TDS} refers to the standard ``A Directory Structure
+% for \TeX\ Files'' (\CTANpkg{tds}). Directories
+% with \xfile{texmf} in their name are usually organized this way.
+%
+% \subsection{Bundle installation}
+%
+% \paragraph{Unpacking.} Unpack the \xfile{rerunfilecheck.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+%   |unzip rerunfilecheck.tds.zip -d ~/texmf|
+% \end{quote}
+%
+% \subsection{Package installation}
+%
+% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
+% \docstrip\ archive. The files are extracted by running the
+% \xfile{.dtx} through \plainTeX:
+% \begin{quote}
+%   \verb|tex rerunfilecheck.dtx|
+% \end{quote}
+%
+% \paragraph{TDS.} Now the different files must be moved into
+% the different directories in your installation TDS tree
+% (also known as \xfile{texmf} tree):

+% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
+% TDS installing feature, then some files can already be in the right
+% place, see the documentation of \docstrip.
+%
+% \subsection{Refresh file name databases}
+%
+% If your \TeX~distribution
+% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
+% these. For example, \TeX\,Live\ users run \verb|texhash| or
+% \verb|mktexlsr|.
+%
+% \subsection{Some details for the interested}
+%
+% \paragraph{Unpacking with \LaTeX.}
+% The \xfile{.dtx} chooses its action depending on the format:
+% \begin{description}
+% \item[\plainTeX:] Run \docstrip\ and extract the files.
+% \item[\LaTeX:] Generate the documentation.
+% \end{description}
+% If you insist on using \LaTeX\ for \docstrip\ (really,
+% \docstrip\ does not need \LaTeX), then inform the autodetect routine
+% about your intention:
+% \begin{quote}
+%   \verb|latex \let\install=y\input{rerunfilecheck.dtx}|
+% \end{quote}
+% Do not forget to quote the argument according to the demands
+% of your shell.
+%
+% \paragraph{Generating the documentation.}
+% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
+% the documentation. The process can be configured by the
+% configuration file \xfile{ltxdoc.cfg}. For instance, put this
+% line into this file, if you want to have A4 as paper format:
+% \begin{quote}
+%   \verb|\PassOptionsToClass{a4paper}{article}|
+% \end{quote}
+% An example follows how to generate the
+% documentation with pdf\LaTeX:
+% \begin{quote}
+%\begin{verbatim}
+%pdflatex rerunfilecheck.dtx
+%makeindex -s gind.ist rerunfilecheck.idx
+%pdflatex rerunfilecheck.dtx
+%makeindex -s gind.ist rerunfilecheck.idx
+%pdflatex rerunfilecheck.dtx
+%\end{verbatim}
+% \end{quote}

+%     The options of this package are recognized only if they are
+%     package options. Global options are ignored. This avoids

+%     (for example, class option `index=totoc').

+%   \begin{Version}{2010/03/15 v1.5}
+%   \item
+%     Call of \cs{pdffivesum} is wrapped in \cs{IfFileExists} to avoid

+%     However \cs{IfFileExists} has file name limitations.
+%   \end{Version}
+%   \begin{Version}{2010/03/16 v1.6}
+%   \item
+%     Reverted to version 1.4 and \cs{IfFileExists} wrapper of
+%     version 1.5 is removed.
