-% \begin{abstract}
-% This package provides macros for adding and reordering
-% graphics extensions of package \xpackage{graphics}.
-% \end{abstract}

-%
-% \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{Option support for package \xpackage{graphicx}}
-%
-% Package \xpackage{graphicx} uses the interface of package
-% \xpackage{keyval} in order to specify options for
-% \cs{includegraphics}. The options can also be set using
-% \begin{quote}
-% |\setkeys{Gin}{|\meta{options}|}|
-% \end{quote}
-% The four user macros with the two star forms are available
-% as options in family |Gin| as well:
-% \begin{quote}
-% |AppendGraphicsExtensions={|\meta{ext-list}|}|\\
-% |AppendGraphicsExtensions*={|\meta{ext-list}|}|\\
-% |PrependGraphicsExtensions={|\meta{ext-list}|}|\\
-% |PrependGraphicsExtensions*{|\meta{ext-list}|}|\\
-% |RemoveGraphicsExtensions={|\meta{ext-list}|}|\\
-% |PrintGraphicsExtensions|
-% \end{quote}
-% This makes it easier to locally change the extension list
-% for an included graphics, e.g.:
-% \begin{quote}
-% |\includegraphics[RemoveGraphicsExtensions={.pdf,PDF}]{image}|
-% \end{quote}
-%
-% \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

-% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{grfext}}:
-% \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[\CTANinstall{install/macros/latex/contrib/oberdiek.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{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}
-%
-% \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):

-% 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{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
