% \begin{abstract}
% The package replaces \cs{includeonly} and selects the files for
% \cs{include} by inspecting the time stamp of the \xext{aux} file.
% The file is selected for inclusion if the \xext{aux} file does
% not yet exist or is older than the corresponding \xext{tex} file.
% \end{abstract}
%
% \tableofcontents
%
% \section{Documentation}
%
% \subsection{Introduction}
% \label{sec:intro}
%
% \LaTeX\ provides two commands \cs{include} and \cs{includeonly}
% that helps in organizing large projects.
% Example for a master file:
%\begin{quote}
%\begin{verbatim}
%\documentclass{book}
%  % \includeonly{}
%\begin{document}
% \include{fileA}
% \include{fileB}
% \include{fileC}
%\end{document}
%\end{verbatim}
%\end{quote}
% All files are read and compiled if \cs{includeonly} is not
% executed. Otherwise you can give \cs{includeonly} a list
% of files in the preamble, e.g.:
% \begin{quote}
%   |\includeonly{fileA,fileC}|
% \end{quote}
% Now only files \xfile{fileA.tex} and \xfile{fileC.tex} are read
% and compiled.
%
% If you change file \xfile{fileB.tex} and want to see only this
% file, then you must change the line with \cs{includeonly} to
% \begin{quote}
%   |\includeonly{fileB}|
% \end{quote}
% It is tedious to do this again and again, if different files
% are changed.
%
% Package \xpackage{askinclude} \cite{askinclude}
% offers a solution for this problem. It interactively asks
% for the files to be included and saves the user from
% editing the master file.
%
% This package \xpackage{stampinclude} goes another way.
% \LaTeX\ reads and writes a separate \xext{aux} file for each
% file that is included by \cs{include}. There \LaTeX\ remembers
% counter valuses. Changed \xext{tex}
% files can therefore be detected by comparing the file date stamp of
% the \xext{tex} file with the date stamp of its \xext{aux} file.
% Since version 1.30.0 \pdfTeX\ provides \cs{pdffilemoddate}
% that reads the file date stamp. Thus this package uses this
% command and redefines
% \cs{include} to include the files that do not have \xext{aux}
% files yet or that are newer than its \xext{aux} file.
% \cs{includeonly} is ignored.
%
% \subsection{Usage}
%
% The package is loaded as normal \LaTeX\ package without options:
% \begin{quote}
%   |\usepackage{stampinclude}|
% \end{quote}
% Alternatively the package may be loaded on the command line
% (Example for shell `bash'):
% \begin{center}
%   |latex '\AtBeginDocument{\usepackage{stampinclude}}\input{master}'|
% \end{center}
% Without \cs{AtBeginDocument} (and \cs{RequirePackage} instead of
% \cs{usepackage}) \TeX\ would name the document \xfile{stampinclude.dvi}
% instead of \xfile{master.dvi}.
%
% \subsection{Limitations}
%
% \subsubsection{Other file dependencies}
%
% A file that is included by \cs{include} may input ore reference
% other files:
% \begin{itemize}
% \item other \TeX\ files using \cs{input},
% \item graphics files (\cs{includegraphics}),
% \item listings of external files,
% \item ...
% \end{itemize}
% Updates of those files are not detected by this package.
% It limits the date stamp comparison of an \xext{aux} file
% to its \xext{tex} file.
%
% \subsubsection{\cs{include} dependencies}
%
% In the example, given in the introduction \ref{sec:intro},
% three files \xfile{fileA}, \xfile{fileB}, and \xfile{fileC}
% are included in this order. Now file \xfile{fileA} is changed by adding
% four pages, \xfile{fileB} remains untouched, and \xfile{fileC} is
% also updated. Then the package only selects \xfile{fileA} and
% \xfile{fileC} for inclusion. File \xfile{fileB} is not included.
% But \LaTeX\ has stored the counter values that are active
% at the end of \xfile{fileB} in \xfile{fileB.aux} in one of the
% previous runs when \xfile{fileB} was included.
% However the later addition of four pages in \xfile{fileA}
% was not known at that time. Therefore \xfile{fileB.aux}
% is out of date and the inclusion of file \xfile{fileC}
% starts with wrong counter values (especially the page counter).
%
% \subsubsection{Summary}
%
% This package \xpackage{stampinclude} and the \cs{include} feature
% helps in accelerating the \LaTeX\ compilation.
% But it is not intended for generating the final version.
% For the final version of the document it is better to include
% \emph{all} files to get all counter values right.
% Then this package and any \cs{includeonly} lines should be commented out:
%\begin{quote}
%  |% \usepackage{stampinclude}|\\
%  |% \includeonly{...}|
%\end{quote}
%
% \subsection{Requirements}
%
% \begin{itemize}
% \item \pdfTeX\ v1.30.0 (because of \cs{pdffilemoddate}
%   and \cs{pdfstrcmp}),\\
%   both modes for DVI and PDF are supported.
% \item Alternatively Lua\TeX\ may be used.
%   It lacks \cs{pdffilemoddate} and \cs{pdfstrcmp}. But its services
%   are provided by package \xpackage{pdftexcmds} \cite{pdftexcmds}
%   that is automatically loaded.
% \end{itemize}

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\url{ftp://ftp.ctan.org/tex-archive/}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/stampinclude.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/stampinclude.pdf}] Documentation.
% \end{description}
%
%
% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
% 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[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}]
% \end{description}
% \emph{TDS} refers to the standard ``A Directory Structure
% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). Directories
% with \xfile{texmf} in their name are usually organized this way.
%
% \subsection{Bundle installation}
%
% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
% TDS tree (also known as \xfile{texmf} tree) of your choice.
% Example (linux):
% \begin{quote}
%   |unzip oberdiek.tds.zip -d ~/texmf|
% \end{quote}
%
% \paragraph{Script installation.}
% Check the directory \xfile{TDS:scripts/oberdiek/} for
% scripts that need further installation steps.
% Package \xpackage{attachfile2} comes with the Perl script
% \xfile{pdfatfi.pl} that should be installed in such a way
% that it can be called as \texttt{pdfatfi}.
% Example (linux):
% \begin{quote}
%   |chmod +x scripts/oberdiek/pdfatfi.pl|\\
%   |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/|
% \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 stampinclude.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
% (\teTeX, \mikTeX, \dots) relies on file name databases, you must refresh
% these. For example, \teTeX\ users run \verb|texhash| or
% \verb|mktexlsr|.
%
% \subsection{Some details for the interested}
%
% \paragraph{Attached source.}
%
% The PDF documentation on CTAN also includes the
% \xfile{.dtx} source file. It can be extracted by
% AcrobatReader 6 or higher. Another option is \textsf{pdftk},
% e.g. unpack the file into the current directory:
% \begin{quote}
%   \verb|pdftk stampinclude.pdf unpack_files output .|
% \end{quote}
%
% \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{stampinclude.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 stampinclude.dtx
%makeindex -s gind.ist stampinclude.idx
%pdflatex stampinclude.dtx
%makeindex -s gind.ist stampinclude.idx
%pdflatex stampinclude.dtx
%\end{verbatim}
