% \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.
% The LaTeX hook \texttt{enddocument/info}
% 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}
%
%
% \subsection{Package installation}
% Typically the package should be installed with the package manager of your \TeX-system.
% A manual installation as described below is needed only very rarely and is described
% only for historical reasons.
%
% \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):
% \begin{quote}

% 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}

% \begin{History}

%     The first version.
%   \end{Version}
%   \begin{Version}{2009/12/12 v1.1}
%   \item
%     Short info shortened.
%   \end{Version}
%   \begin{Version}{2009/12/18 v1.2}
%   \item
%     Required date for package \xpackage{uniquecounter} updated
%     because of bug in this package.
%   \end{Version}

%   \end{Version}
%   \begin{Version}{2010/02/22 v1.4}
%   \item
%     The options of this package are recognized only if they are
%     package options. Global options are ignored. This avoids
%     name clashes with class and other package options
%     (for example, class option `index=totoc').
%   \end{Version}
%   \begin{Version}{2010/03/15 v1.5}
%   \item
%     Call of \cs{pdffivesum} is wrapped in \cs{IfFileExists} to avoid
%     calls of \textsf{mktextex} if this feature is enabled.
%     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.
