%
% \subsection{Introduction}
%
% \LaTeX\ provides its graphics bundle to include graphics files.
% Both packages \xpackage{graphics} or \xpackage{graphicx} may
% be used. the latter one loads the first and adds options
% in key value style for \cs{includegraphics}.
%
% Usually the drivers do not support all kind of graphics files.
% Other image types must be converted, before they become
% usuable. In case of driver \xprogram{dvips}, the graphics
% rule may contain a conversion rule. Then all that package
% \xpackage{graphics} must know is the bounding box, the command
% is passed to \xprogram{dvips} that calls it and embeds the
% converted image.
%
% However, \pdfTeX\ has its driver for PDF output already
% build in. It's graphics inclusion commands (\cs{pdfximage})
% does not allow the execution of external commands.
% Therefore commands in the last argument of
% \cs{DeclareGraphicsRule} were of no use.
% But external programs can be called within \pdfTeX.
% This feature is called ``shell escape'' or ``write 18''
% and must usually enabled explicitely because of security reasons.
% Now, this package \xpackage{epstopdf} hooks
% into package \xpackage{graphics}' code to catch
% that argument with the external command and executes it
% to convert the graphics file to a supported format and
% passes the control of graphics inclusion back to package
% \xpackage{graphics}.
%
% \subsection{Requirements}
%
% \begin{itemize}
% \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 \TeX. Mik\TeX\ and \TeX\ Live support it.
%   In Web2C based \TeX\ distributions (\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} (\TeX\ Live)\\
%   \texttt{--enable-write18} (MiK\TeX)
%   \end{quote}
%   Example:
%   \begin{quote}
%     |pdflatex -shell-escape test.tex|
%   \end{quote}
% \item
%   The program \xprogram{epstopdf} for the conversion from EPS
%   to PDF. However, other programs can
%   be used and configured by \cs{DeclareGraphicsRule}.
%   Example:
%   \begin{quote}
%   |\epstopdfDeclareGraphicsRule{.eps}{pdf}{.pdf}{%|\\
%   |  ps2pdf -dEPSCrop #1 \OutputFile|\\
%   |}|
%   \end{quote}
% \end{itemize}
%
% \subsection{Usage}
%
% The package is loaded after graphic\{s,x\}, e.g.:
% \begin{quote}
%   |\usepackage[pdftex]{graphicx}|\\
%   |\usepackage{epstopdf}|
% \end{quote}
% Now images with file name extension \xfile{.eps} are detected
% and supported using \cs{includegraphics}.
%
% If the graphics file name is explicitly specified with extension
% \xfile{.eps} the new rule for EPS files is called and
% the conversion performed. If option \xoption{update} is in force
% then the conversion step is dropped if the target file already
% exists and is not older then the EPS file.
%
% The situation is more complicate if the graphics file is
% given without file name extension. Then the \xpackage{graphics}
% package must search for a supported image file.
% The possible extensions are stored in the graphics extension
% list, that can be set by \cs{DeclareGraphicsExtensions}.
% The algorithm:
% \begin{quote}
%    \def\>{\mbox{}\quad}
%    function search( \meta{filebase} )\\
%    \>foreach \meta{ext} in \meta{graphics extensions}\\
%    \>\>foreach \meta{dir} in \meta{current directory}, \meta{\cs{graphicspath}}\\
%    \>\>\>\meta{file} := \meta{dir} + \meta{filebase} + \meta{ext}\\
%    \>\>\>if exist \meta{file}\\
%    \>\>\>\>return found\\
%    \>return not found
% \end{quote}
% Package \xpackage{epstopdf} puts \xfile{.eps} at the end of the
% graphics extension search list. This is the behaviour of option
% \xoption{append} that is enabled by default.
% That means, the conversion is called last
% unless a supported file type cannot be found earlier. This avoids
% unnecessary conversion steps that slow down the \LaTeX\ run.
% If you want to use option \xoption{update} and your \pdfTeX\ supports
% it, then an outdated PDF file also would be found earlier unless
% \xoption{suffix} is used that is the default since version 2.0.
%
% With an empty option \xoption{suffix} and option
% \xoption{prepend} there is a risk that an original PDF file is overwritten:
%
% If the original image file is the PDF file and there is also a generated
% EPS file, then the original PDF file can be regenerated (depending
% on the option settings) and the original PDF file gets lost.
% Therefore option \xoption{suffix} is introduced in version 1.9
% to create a separate name space for generated output files.
%
% \textbf{Note:} Usually the conversion program needs the exact location
% of the image file. Usually the current directory works.
% Also if the image file is found using \cs{graphicspath}, the
% location is known. However, if the image is somewhere
% in a directory of environment variable |TEXINPUTS|, then
% the package does not know the exact location and the
% conversion program will not find the image file unless it
% implements a search using |TEXINPUTS| (program \xprogram{kpsewhich}
% may be of help in this task).
%
% \subsection{Options}
%
% Options can be given as package options or later using:
% \begin{declcs}{epstopdfsetup} \M{key value list}
% \end{declcs}
% \LaTeX\ expands the option list before passing the option list
% to the package's option handling code. This can fail
% for option \xoption{suffix} if it contains some of the macros
% described below. Use \cs{epstopdfsetup} after the package is loaded.
% Or load package \xpackage{kvoptions-patch} before. This package
% is also loaded by option \xoption{patch} of package \xpackage{kvoptions}.
% \LaTeX's option code is redefined to respect key value options and
% let the values untouched.
%
% \begin{description}
% \def\It#1{\item[\xoption{#1}:]}^^A
% \It{update}
%   The conversion program is only called, if the target file
%   does not exist or is older than the source image file.
% \It{append}
%   Puts the extension \xfile{.eps} at the end of the graphics extension list
%   (default).
% \It{prepend}
%   Puts the extension \xfile{.eps} at the begin of the graphics extension list.
% \It{outdir}
%   The converted file may put in an other output directory.
%   The value of \xoption{outdir} must include the directory separator.
%   Example for the current directory:
%   \begin{quote}
%   |\epstopdfsetup{outdir=./}|
%   \end{quote}
%   For other directories ensure, that they can be found.
%   See \cs{graphicspath} or |TEXINPUTS|.
% \It{suffix}
%   This option takes a string that is put between the file name base
%   and the extension of the output file. Rationale: It can happen,
%   that a PDF file is the original file and the EPS file the
%   generated file. If now the package thinks, that the PDF file
%   is the generated file, it will `regnerate' it. But in reality
%   the original file is lost. Therefore I recommend to use this
%   option always to generate a separate name space for generated
%   files. Proposed value is \texttt{-generated} or \texttt{.generated}.
%   The suffix \texttt{.generated} will also work here without the need for
%   package \xpackage{grffile}).
%
%   Example:
%   \begin{quote}
%   |\epstopdfsetup{suffix=-generated}|\\
%   Then \xfile{foo.eps} is converted to \xfile{foo-generated.pdf}.
%   \end{quote}
%   \cs{SourceExt} can be used inside the suffix string.
%   It's will be replaced by the extension of the image source
%   file without the leading dot, for instance:
%   \begin{quote}
%   |\epstopdfsetup{suffix=-\SourceExt-converted-to}|\\
%   \xfile{foo.eps} $\Rightarrow$ \xfile{foo-eps-converted-to.pdf}
%   \end{quote}
%   See also the next option \xoption{prefersuffix} that
%   modifies the behaviour of option \xoption{suffix} in some
%   cases.
%
%   Default for \xoption{suffix} is `|-\SourceExt-converted-to|'.
%
% \It{prefersuffix}
%   If a suffix is set by option \xoption{suffix}, then there can be
%   two image file names that could be taken into account for inclusion:
%   A image file name with the suffix string inside
%   its name and a image file name without; e.g. for \xfile{foo.eps}
%   the names could be:
%   \begin{quote}
%   \xfile{foo-suffix.pdf}, \xfile{foo.pdf}
%   \end{quote}
%   If option \xoption{perfersuffix} is turned on, the
%   file \xfile{foo-suffix.pdf} and its generation is preferred
%   over using \xfile{foo.pdf}. Otherwise \xfile{foo.pdf} is included
%   without generating \xfile{foo-suffix.pdf}.
%   The default of option \xoption{prefersuffix} is \texttt{true}.
% \It{program@epstopdf}
%   The name for the conversion program from EPS to PDF,
%   default is `|epstopdf|'.
% \It{verbose}
%   It prints some information about the image in the \xfile{.log} file
%   (default).
% \end{description}
%
% \subsection{Configuration}
%
% \subsubsection{System configuration file \xfile{epstopdf-sys.cfg}}
%
% If \xfile{epstopdf-sys} exists it is loaded at the end of the
% package \xpackage{epstopdf-base} and before the user configuration
% file. It's intended for TeX distributors. Thus they could add
% additional conversion rules (e.g., .gif -> .png) or set options.
%
% \subsubsection{User configuration file \xfile{epstopdf.cfg}}
%
% A configuration file \xfile{epstopdf.cfg} is loaded at the end
% of the package if it exists. It can be used for changing
% the default option setting. Example:
% \begin{quote}
% |\epstopdfsetup{verbose=false}|
% \end{quote}
%
% \subsubsection{Conversion program}
%
% You can use \cs{DeclareGraphicsRule} in a similar way as the
% route via \xprogram{dvips} to specify the conversion
% command line.
% The conversion argument starts with a back tick, followed
% by the conversion command including parameters.
%
% The whole conversion argument should also be wrapped inside
% \cs{epstopdfcall}. This reduces the problem with packages
% (e.g. \xpackage{pst-pdf}) that use the conversion argument
% and expands it. Macros \cs{SourceFile}, \cs{OutputFile}, and
% \cs{SourceExt} are not defined outside \xpackage{epstopdf-base}'s
% \cs{Gin@setfile} and error messages because of undefined
% command names are the result. If \cs{epstopdfcall} detects that
% it is called outside \xpackage{epstopdf-base}'s \cs{Gin@setfile}
% then it replaces the conversion argument by
% package \xpackage{graphics}'s
% default, usually the image file.
%
% The following macros are available inside:
% \begin{description}
% \def\It#1{\item[\cs{#1}:]}
% \It{OutputFile}: output file name (with known path and extension)
% \It{SourceFile}: source file name (with known path and extension),
%                  usually the same as |#1|,
% \It{SourceExt}: source extension without leading dot.
% \end{description}
%
% \paragraph{Conversion from EPS to PDF.}
% Other programs than \xprogram{epstopdf} can be used to convert from
% EPS to PDF. Example that uses \xprogram{Ghostscript}:
% \begin{quote}
%   |\DeclareGraphicsRule{.eps}{pdf}{.pdf}{%|\\
%   | \epstopdfcall{`ps2pdf -dEPSCrop #1 \noexpand\OutputFile}%|\\
%   |}|
% \end{quote}
% \cs{DeclareGraphicsRule} expands the argument, therefore \cs{noexpand}
% is necessary. As convenience package \xpackage{epstopdf-base} defines
% \cs{epstopdfDeclareGraphicsRule}. Then the conversion argument
% is not expanded, \cs{epstopdfcall} and the back tick are added:
% \begin{quote}
%   |\epstopdfDeclareGraphicsRule{.eps}{pdf}{.pdf}{%|\\
%   |  ps2pdf -dEPSCrop #1 \OutputFile|\\
%   |}|
% \end{quote}
%
% Also \cs{OutputFile} respects the setting of option \xoption{outdir}.
%
% \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}
%\epstopdfDeclareGraphicsRule{.gif}{png}{.png}{%
%  convert #1 \OutputFile
%}
%\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}.
% \begin{quote}
% |\AppendGraphicsExtensions{.gif}|\\
% or\\
% |\PrependGraphicsExtensions{.gif}|
% \end{quote}

% \subsubsection{Load packages}
%
% This package is split into \xpackage{epstopdf-base} and \xpackage{epstopdf}
% The base version is called directly by the \xpackage{graphics} package. Unfortunately
% it still includes many contributed packages  which breaks the layering of the core
% \LaTeX\ graphics release.
%
% Compatibility concerns mean refactoring the package to only have options 
% in \xpackage{epstopdf}  is tricky, so from release 2.8, if no options have been passed in
% to \xpackage{epstopdf-base}, the package loading and option setting are skipped and the default
% settings are set directly. In the case of Lua\TeX, the Lua portion of \xpackage{pdftexcmds}
% is used to provide the file handling functionality.

%
%
% \paragraph{Bundle.} All the packages of the bundle `epstopdf'
% 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.

% \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{epstopdf.tds.zip} in the
% TDS tree (also known as \xfile{texmf} tree) of your choice.
% Example (linux):
% \begin{quote}
%   |unzip epstopdf.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 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):

% 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{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}
