%
% \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.
% \end{abstract}
%
% \tableofcontents
%
% \section{Usage}
%\begin{verbatim}
% Required:  * The program `epstopdf'.
%            * The feature `\write18' has to be enabled to get
%              the conversion via the program epstopdf work:
%              * command line option: -shell-escape
%                example: pdflatex -shell-escape test.tex
%              * configuraton file `texmf.cnf': shell_escape = 1
%
% Use:       The package is loaded after graphic{s,x}, eg:
%              \usepackage[pdftex]{graphicx}
%              \usepackage{epstopdf}
%            Images with extension `.eps' are now detected
%            and supported:
%            * Implicitly: \includegraphics{bild}
%              If `bild.eps' can only be found,
%              then it is converted to the file `bild.pdf',
%              that will be used by pdfTeX.
%              On the next ocurrences or on the next pdfTeX run,
%              the pdf file is already available, so the
%              conversion step is skipped.
%            * Explicitly: \includegraphics{bild.eps}
%              Each time the conversion program is called.

%    \end{macrocode}
% \section{Installation}
%
% \paragraph{CTAN.} 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{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}
% \sbox0{^^A
% \begin{tabular}{@{}>{\ttfamily}l@{$\quad\rightarrow\quad$}>{\ttfamily}l@{}}
%   epstopdf.sty & tex/latex/oberdiek/epstopdf.sty\\
%   epstopdf.pdf & doc/latex/oberdiek/epstopdf.pdf\\
%   epstopdf.dtx & source/latex/oberdiek/epstopdf.dtx\\
% \end{tabular}^^A
% }%
% \ifdim\wd0>\linewidth
%   \mbox{}\nobreak\hskip0pt minus\leftmargin
%   \usebox0
%   \nobreak\hskip0pt minus\rightmargin
% \else
%   \usebox0
% \fi
% \end{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.
%
% \paragraph{Refresh file databases.} If your \TeX~distribution
% (\teTeX, \mikTeX, \dots) rely on file 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}
% \end{quote}
%
% \begin{History}
%   \begin{Version}{2001/01/06 v1.0}
%   \item
%     First public version,
%     published in the \pdfTeX\ mailing list.
%   \end{Version}
%   \begin{Version}{2001/02/04 v1.1}
