% \begin{abstract}
% This packages adds support of handling eps images
% to package \xpackage{graphics} or \xpackage{graphicx}
% with option \xoption{pdftex}. If an eps image is detected,
% epstopdf is automatically called to convert it to pdf format.

% \section{Documentation}
%
% \subsection{Requirements}
%
% \begin{itemize}
% \item
%   The program \xprogram{epstopdf} for the conversion from EPS
%   to PDF. However, other programs can
%   be used and configured by \cs{DeclareGraphicsRule}.
% \item
%   The feature \cs{write18} must be enabled. This allows the
%   running of external programs during \TeX's compile run.
%   Keep in mind that this is a security risk. The feature is an
%   addition to \cs{TeX}. Mik\TeX, te\TeX, \TeX\ Live support it.
%   In Web2C based \TeX\ distributions (te\TeX, \TeX\ Live) it can be
%   enabled in the configuration file \xfile{texmf.cnf}:
%   \begin{quote}
%     |shell_escape = 1|
%   \end{quote}
%   Because of the security risk, it is better to do it on the
%   command line only:
%   \begin{quote}
%   \texttt{-shell-escape} (te\TeX, \TeX\ Live)\\
%   \texttt{--enable-write18} (MiK\TeX)
%   \end{quote}
%   Example:
%   \begin{quote}
%     |pdflatex -shell-escape test.tex|
%   \end{quote}
% \end{itemize}
%
% \section{Usage}
%
% The package is loaded after graphic\{s,x\}, e.g.:
% \begin{quote}
%   |\usepackage[pdftex]{graphicx}|\\
%   |\usepackage{epstopdf}|
% \end{quote}
% Now images with extension `.eps' are detected
% and supported:
% \begin{itemize}
% \item
%   Implicitly: |\includegraphics{bild}|\\
%   If \xfile{bild.eps} is present, but \xfile{bild.pdf} is missed,
%   then \xfile{bild.eps} is converted to \xfile{bild.pdf} that
%   is then included by \pdfTeX.
%   On the next ocurrences or on the next \pdfTeX\ run,
%   the PDF file is already available, so the
%   conversion step is skipped.
% \item
%   Explicitly: |\includegraphics{bild.eps}|\\
%   Each time the conversion program is called.
% \end{itemize}
%
% \subsection{Configuration}
%
% Package \xpackage{epstopdf} implements the forth argument
% of \cs{DeclareGraphicsRule} for \pdfTeX. There conversion programs
% can be configured and package \xpackage{epstopdf} declares:
% \begin{quote}
%   |\DeclareGraphicsRule{.eps}{pdf}{.pdf}{`epstopdf #1}|
% \end{quote}
% Additionally the extension \xfile{.eps} is added to the
% list of extensions that are recognized by package \xpackage{graphics},
% see \cs{GraphicsExtensions}.
%
% Instead of \xprogram{epstopdf} other programs can be used,
% for example \xprogram{ghostscript}:
% \begin{quote}
%   |\DeclareGraphicsRule{.eps}{pdf}{.pdf}{`ps2pdf -dEPSCrop #1}|
% \end{quote}
%
% \subsection{Other image formats}
%
% The support that package \xpackage{epstopdf} implements is not
% limited to EPS files. Other image conversions can be declared.
% The following example shows it for GIF images under Unix with
% ImageMagick's \xprogram{convert}:
%\begin{quote}
%\begin{verbatim}
%\DeclareGraphicsRule{.gif}{png}{.png}{%
%  `convert #1 `basename #1 .gif`.png%
%}
%\end{verbatim}
%\end{quote}
% Or without \xprogram{basename}:
%\begin{quote}
%\begin{verbatim}
%\makeatletter
%\DeclareGraphicsRule{.gif}{png}{.png}{%
%  `convert #1 \noexpand\Gin@base.png%
%}
%\makeatother
%\end{verbatim}
%\end{quote}
% The file extension \xfile{.gif} can be added to the extension list that
% package \xpackage{graphics} searches if the file extension
% is not given in \cs{includegraphics}.
% The list can be set by \cs{GraphicsExtensions}.
% The following example shows another way by adding \xfile{.gif} to the
% list:
%\begin{quote}
%\begin{verbatim}
%\makeatletter
%\g@addto@macro\Gin@extensions{,.gif}
%\makeatother
%\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/epstopdf.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/epstopdf.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 epstopdf.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

% 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 epstopdf.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{epstopdf.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 epstopdf.dtx
%makeindex -s gind.ist epstopdf.idx
%pdflatex epstopdf.dtx
%makeindex -s gind.ist epstopdf.idx
%pdflatex epstopdf.dtx
%\end{verbatim}
