+% \section{Documentation}
+%
+% \subsection{Introduction}
+%
+% If you are not familiar with \LaTeX's graphics bundle, please
+% read its documentation \xfile{grffile} \cite{graphics}.
+% The bundle contains two packages for graphics inclusion:
+% \xpackage{graphics} and \xpackage{graphicx}. The first one
+% is loaded by the second one that adds a key value interface.
+%
+% Graphics files are included in both cases by macro
+% \cs{includegraphics}. The file name extension can be omitted.
+% Then the graphics package goes through a list of known
+% extensions until it finds the graphics file. This extension list
+% is set by \cs{DeclareGraphicsExtensions}. The previous contents
+% of the list is overwritten.
+%
+% \subsection{User interface}
+%
+% This package \xpackage{grfext} provides macros that adds entries
+% to the list or remove them. The list may be empty or even
+% undefined before. It is always defined afterwards, but can
+% be empty (especially after removing entries).
+%
+% \begin{declcs}{AppendGraphicsExtensions} * \M{ext-list}\\
+% \cs{PrependGraphicsExtensions} * \M{ext-list}
+% \end{declcs}
+% The argument \meta{ext-list} is a comma separated list whose
+% entries are file name extensions including the dot.
+% But first the entries are removed from
+% \xpackage{graphics}' extension list to avoid multiple
+% occurences of the same extension.
+%
+% Then macro \cs{AppendGraphicsExtensions} adds the entries
+% after the end of \xpackage{graphics}' list, whereas
+% macro \cs{PrependGraphicsExtensions} puts them in front
+% of the list.
+% The order matters if a graphics file is available in
+% different acceptable formats. Then the first extension
+% wins.
+%
+% The star version of these commands only adds an extensions,
+% if a specific graphics rule exists for that extension.
+%
+% \begin{declcs}{RemoveGraphicsExtensions} \M{ext-list}
+% \end{declcs}
+% All occurences of file extensions in \meta{ext-list} are
+% removed from \xpackage{graphics}' extension list.
+%
+% \subsection{Package loading}
+%
+% The package does not define any options. It is loaded
+% as usual in \LaTeX, e.g.:
+% \begin{quote}
+% |\usepackage{grfext}|
+% \end{quote}
+%
+% \begin{declcs}{PrintGraphicsExtensions}
+% \end{declcs}
+% Macro \cs{PrintGraphicsExtensions} writes the current
+% graphics extensions list in the \xfile{.log} file.
+% The macros described before do this automatically
+% after their operation.
+%
+% \subsection{\plainTeX}
+%
+% \LaTeX's graphics packages can also be used with \plainTeX.
+% The necessary basic \LaTeX\ macros are defined in
+% \xfile{miniltx.tex}. This package \xpackage{grfext} also
+% relies on it. Example:
+%\begin{quote}
+%\begin{verbatim}
+%\input miniltx.tex\relax
+%\def\Gin@driver{pdftex.def}
+%\input graphicx.sty\relax
+%\input grfext.sty\relax
+%\resetatcatcode
+%\end{verbatim}
+%\end{quote}

+% \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/grfext.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/oberdiek/grfext.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{macros/latex/contrib/oberdiek/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 grfext.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}
+% \def\t{^^A
+% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}}

+% 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 grfext.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{grfext.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 grfext.dtx
+%makeindex -s gind.ist grfext.idx
+%pdflatex grfext.dtx
+%makeindex -s gind.ist grfext.idx
+%pdflatex grfext.dtx
+%\end{verbatim}
+% \end{quote}
