% \begin{abstract}
% The package extends the file name processing of package \xpackage{graphics}
% to support a larger range of file names. For example, the file name
% may contain several dots. Or in case of \pdfTeX\ in PDF mode the file name may
% contain spaces.
% \end{abstract}
%
% \tableofcontents
%
% \section{Usage}
%
% \subsection{Option \xoption{multidot}}
%
% The file name parsing of package \xpackage{graphics} is changed, in order
% to detect known extensions. This allows both the use of dots inside the
% base file name and extensions with several dots.
%
% Assume there are two files in the currect directory: \texttt{Hello.World.eps}
% and \texttt{Hello.World.pdf}.  \verb|\includegraphics{Hello.World}| will find
% \verb|Hello.World.pdf| with driver \xoption{pdftex} or
% \verb|Hello.World.eps| with driver \xoption{dvips}.
%
% \paragraph{Limitations:} Problem could occur on systems, which don't
% use the dot as extension delimiter. These systems needs an own
% \verb|texsys.cfg| containing definitions for \verb|\filename@parse|.
% The author could not test that, due to a missing example.
%
% \subsection{Option \xoption{babel}}
%
% This option allows the use of shorthand characters of package
% \xpackage{babel} inside the graphics file name. Additionally
% the tilde `\textasciitilde' is supported. The option
% is turned on as default. (In version v1.1 or below of this package,
% the features of this option were part of option \xoption{extendedchars}.)
%
% Example:
% \begin{quote}
%\begin{verbatim}
%\usepackage[frenchb]{babel}
%\usepackage{grffile}
%Image: \includegraphics{C:/path/image}
%\end{verbatim}
% \end{quote}
%
% \subsection{Option \xoption{extendedchars}}
%
% If the input encoding is the same encoding as the encoding that
% is used for file names and the driver allows non-ascii characters.
% Without option \xoption{extendedchars} the 8-bit characters
% are expanded, if they are active characters. For example,
% see the \LaTeX\ package \xpackage{inputenc}. However a
% file name is not input for \LaTeX. Therefore this option
% \xoption{extendedchars} removes the active status and
% the 8-bit characters are not expandable any more.
%
% Example:
% \begin{quote}
%   |\usepackage[latin1]{inputenc}|\\
%   |\usepackage[extendedchars]{grffile}|\\
%   |\includegraphics{|\texttt{B\"ackerstra\ss e}|}|
% \end{quote}
%
% If the \verb|draft| option of the graphics package is enabled, the
% file name is printed with the current font encoding for \verb|\ttfamily|.
% Thus it is possible, that such characters are omitted or the wrong
% characters are displayed, if the font encoding is not the same as
% the file name encoding.
%
% \subsection{Option \xoption{encoding}}
%
% Consider the following scenario. Your file system is using
% UTF-8 as encoding for file names. But you use \xoption{latin1}
% as input encoding for your \TeX\ files, because some packages
% are not ready for multi-byte encodings (\xpackage{listings}, \dots).
%
% Then this option \xoption{encoding} loads support for converting
% encodings by loading package \xpackage{stringenc}.
% The option is not defined after the preamble, because
% \LaTeX\ limits package loading to the preamble.
%
% File names are converted, if package \xpackage{stringenc} is loaded
% and the encodings are known, see options \xoption{inputencoding} and
% \xoption{filenameencoding}.
%
% \subsubsection{Option \xoption{inputencoding}}
%
% Option \xoption{inputencoding} specifies the encoding
% of the file name in your \TeX\ input file.
%
% Package \xpackage{inputenx} and package \xpackage{inputenc}
% since version 2006/02/22 v1.1a remember the name of
% the input encoding that is looked up by this package.
% Therefore option \xoption{inputencoding} is usually
% not mandatory.
%
% \subsubsection{Option \xoption{filenameencoding}}
%
% This is the encoding of the filename of your file
% system. This option is mandatory, file names
% are not converted without this option. The option
% is disabled, if the value is empty.
%
% \subsubsection{Example}
%
% Back to the scenario where the file system uses UTF-8 and
% the \LaTeX\ input files are encodind in latin1.
% \begin{quote}
%\begin{verbatim}
%\usepackage[latin1]{inputenc}[2006/02/22]
% % \usepackage[latin1]{inputenx}
%\usepackage{graphicx}
%\usepackage[encoding,filenameencoding=utf8]{grffile}
%\end{verbatim}
% \end{quote}
%
% For older versions of package \xoption{inputenc} option
% \xoption{inputencoding} provides the necessary informations.
% \begin{quote}
%\begin{verbatim}
%\usepackage[latin1]{inputenc}
%\usepackage{graphicx}
%\usepackage{grffile}
%\grffilesetup{
%  encoding,
%  inputencoding=latin1,
%  filenameencoding=utf8,
%}
%\end{verbatim}
% \end{quote}
%
% \subsection{Option \xoption{space}}
%
% This option allows graphics file names that contain spaces
% if possible.
%
% In general it is not possible to use space inside file names,
% because \TeX\ considers the space character as termination in its
% syntax for commands that expect a file name.
%
% Regarding graphics inclusion with the package \xpackage{graphics}
% file names are used in two or three contexts:
% \begin{enumerate}
% \item The basic \cs{special} statement or primitive command for
%       graphics inclusion. The \cs{special} statements for
%       drivers \xoption{dvips} or \xoption{dvipdfm} do not allow
%       spaces. However \pdfTeX's primitive \cs{pdfximage}
%       uses curly braces to delimit the file name and allows spaces.
%       In case of \hologo{XeTeX} file names can be enclosed in quotes
%       to support spaces (at the cost that quotes no longer work).
% \item \cs{includegraphics} checks the existence of the file.
%       Also it looks for the right extension if the extension is
%       not given.
%
%       If \pdfTeX\ 1.30 is given, the file existence test
%       can be rewritten using a new primitive that allows spaces.
%       This works in both modes DVI and PDF.
%
%       In case of \hologo{XeTeX} the file existence test is rewritten
%       to automatically add quotes.
% \item Sometimes files are read as \TeX\ input files. For example,
%       \verb|.bb| files or MPS files.
% \end{enumerate}
% If \pdfTeX\ 1.30 or greater is used in PDF mode then the
% graphics file names may contain spaces except for MPS files.
% Therefore option \xoption{space} is only enabled by default,
% if the supported \pdfTeX\ in PDF mode is detected or \hologo{XeTeX}
% is running.
% You can enable the option manually, if you know, your DVI driver
% supports spaces in its \cs{special} syntax and if there is no
% need to read the image file as \TeX\ input file (third context).
%
% \subsection{General use}
%
% The options can be given at many places:
%
% \begin{enumerate}
% \item As package options:\\
%       \verb|\usepackage[<options>]{grffile}|
% \item Setup command of package \xpackage{grffile}:\\
%       \verb|\grffilesetup{<options>}|
% \item The options are also available as options
%       for package \xpackage{graphicx}:\\
%       \verb|\setkeys{Gin}{<options>}|
% \item If package \xpackage{graphicx} is loaded the options can also be
%       applied for a single image:\\
%       \verb|\includegraphics[<options>]{...}|
% \end{enumerate}
%

% \section{Implementation}
%
% \subsection{New Package status.}
% Changes to the core \verb|graphics| code have made the main features of this package
% (supporting multiple dots and spaces in filenames) unneeded as they
% are supported in the core code. The changes in the core also mean
% some patches in this package no longer work.
%
% So by default this package does nothing but (especially if you have
% rolled back other aspects of the latex code) you may want the
% original version, which is available as

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\url{http://ctan.org/pkg/grffile}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/grffile/grffile.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/grffile/grffile.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{install/macros/latex/contrib/grffile.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 grffile.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
% (\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 grffile.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{grffile.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 grffile.dtx
%makeindex -s gind.ist grffile.idx
%pdflatex grffile.dtx
%makeindex -s gind.ist grffile.idx
%pdflatex grffile.dtx
%\end{verbatim}
% \end{quote}

    The package extends the file name processing of package
    <xref refid='graphics'>graphics</xref> to support a larger range
    of file names. For example, the file name may contain several dots.

    Or in case of <xref refid='pdftex'>pdfTeX</xref> in PDF mode the
    file name may contain spaces.
    <p/>
    The package is part of the <xref refid='oberdiek'>oberdiek</xref>
    bundle.
