% \begin{abstract}
% This package embeds files to a PDF document.
% Currently \pdfTeX\ >= 1.30 in PDF mode is supported only.
% \end{abstract}
%
% \tableofcontents
%
% \section{Documentation}
%
% \subsection{Introduction}
%
%    The PDF format (\cite{pdfspec}) allows the inclusion of files
%    inside the PDF document. The included files can be bound to an
%    annotation on a page. Or they can be recorded in a sorted
%    list of embedded files. The packages \xpackage{attachfile}
%    or \xpackage{attachfile2} follow the first approach, this
%    package uses the latter method.
%
% \subsubsection{Future development}
%
%    My dream is a large package that merges the features of
%    all these packages meantioned before:
%    \begin{itemize}
%    \item Files can be attached to a page.
%    \item Files can be attached to the document.
%    \item An easy user interface for simple, common tasks and
%          beginners.
%    \item An interface for the advanced users that want to setup
%          every detail.
%    \item Support of many drivers (pdftex, dvips, dvipdfm, \dots).
%    \item \dots
%    \end{itemize}
%    However, I have not managed to take the time for this project.
%    Instead:
%    \begin{itemize}
%    \item First I experimented with package \xpackage{attachfile},
%          adding driver support, fixing bugs, \dots. The result is
%          currently named as \xpackage{attachfile2}. It uses an external
%          script to get file properties (size, date, checksum, \dots).
%    \item In order to avoid an external program for getting basic
%          file properties I provided a patch ``EscapeAndOther'' for
%          pdfTeX that was accepted for version 1.30.
%    \item This package closes a gap left by the packages for attaching
%          files and allows the embedding of files to the document.
%          Also it makes use of the new primitives of \pdfTeX.
%    \end{itemize}
%
% \subsection{User interface}
%
%    This package \xpackage{embedfile} can be used with both
%    \LaTeX\ and \plainTeX. See \autoref{sec:plain} that
%    explains the use with \plainTeX\ by an example.
%    In \LaTeX\ the package is loaded as usually. There are no options.
%    \begin{quote}
%      \verb|\usepackage{embedfile}|
%    \end{quote}
%
%    \begin{declcs}{embedfile}
%      |[|\meta{options}|]| \M{file}
%    \end{declcs}
%    The macro \cs{embedfile} includes file \meta{file} and
%    attaches it to the PDF document. At the end of the document
%    the sorted list of embedded files are written. Thus you can
%    safely use \cs{embedfile} before \verb|\end{document}|.
%    Embedding files using \cs{AtEndDocument} will only work,
%    if \cs{AtEndDocument} is called before loading the package
%    \xpackage{embedfile}
%
%    The \meta{options} are give as key value pairs. The following
%    keys are supported:
%    \begin{description}
%    \item[\xoption{filespec}]
%      This allows to override the file name
%      that appears in the PDF file. If you are using other than
%      simple file names (8bit, path separators, \dots), look into
%      the PDF specification (\cite{pdfspec}).
%      There are rules how these file names
%      must be written/encoded.
%    \item[\xoption{filesystem}]
%      This sets the entry \verb|/FS| in
%      the file specification dictionary, see PDF specification
%      (\cite{pdfspec}).
%      Example: \verb|filesystem=URL|.
%    \item[\xoption{mimetype}]
%      This sets the mime type (\cite{mime}) of the file,
%      see \autoref{sec:plain} for examples and \cite{types}
%      for a list of officially registered types.
%    \item[\xoption{desc}]
%      The description for the file.
%    \item[\xoption{stringmethod}]
%      The package must convert the values of the keys \xoption{filespec}
%      and \xoption{desc} into a PDF string. If \xpackage{hyperref}
%      is found, then its \cs{pdfstringdef} will be used, otherwise
%      \pdfTeX's \cs{pdfescapestring} is used. Value \verb|psd|
%      forces the use of \cs{pdfstringdef}, value \verb|escape|
%      the use of \cs{pdfescapestring}.
%    \end{description}
%
% \subsection{Examples}
%
% \subsubsection{\plainTeX}\label{sec:plain}
%
%    The package can be used with \plainTeX. Because is uses
%    package \xpackage{keyval} and \cs{@ifnextchar}, it needs
%    a little help from \xfile{miniltx.tex}.
%
%    If additionally package \xpackage{keyval} (\xpackage{graphicx})
%    is needed, load it first. Then package \xpackage{embedfile} avoids
%    a duplicate loading of package \xpackage{keyval}.
%
%    Because \plainTeX\ does not provide a hook at end of the document,
%    you have to call \cs{embedfilefinish} manually at the end
%    after the last embedded file.
%    \begin{macrocode}
%<*exampleplain>
  % Load packages
\input miniltx
  % \def\Gin@driver{pdftex.def}
  % \input graphicx.sty
\input embedfile.sty
\resetatcatcode

  % default setting
\embedfilesetup{
  mimetype=text/plain
}

  % Embed files
\embedfile[
  filespec=example.tex,
  desc={Source code (plain-TeX) of this example}
]{embedfile-example-plain.tex}

\embedfile[
  desc={Source of package `embedfile'}
]{embedfile.dtx}

\embedfile[
  mimetype=application/pdf,
  desc={Documentation of package `embedfile'}
]{embedfile.pdf}

  % Some text
This example document contains three embedded files.

  % End of document
\embedfilefinish % don't forget
\bye
%</exampleplain>
%    \end{macrocode}
%
% \subsection{Package \xpackage{dtx-attach}}
%
% Package \xpackage{dtx-attach} is just a small application of
% package \xpackage{embedfile}. I am using it for the CTAN
% documentation of my packages in \CTAN{macros/latex/contrib/oberdiek/}.
% It also serves as small example for the use of the package with \LaTeX.

% \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/embedfile.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/embedfile.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}
%
% \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 embedfile.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@{}}
%   embedfile.sty & tex/latex/oberdiek/embedfile.sty\\
%   dtx-attach.sty & tex/latex/oberdiek/dtx-attach.sty\\
%   embedfile.pdf & doc/latex/oberdiek/embedfile.pdf\\
%   embedfile-example-plain.tex & doc/latex/oberdiek/embedfile-example-plain.tex\\
%   embedfile.dtx & source/latex/oberdiek/embedfile.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.
%
% \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 embedfile.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{embedfile.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 embedfile.dtx
%makeindex -s gind.ist embedfile.idx
%pdflatex embedfile.dtx
%makeindex -s gind.ist embedfile.idx
%pdflatex embedfile.dtx
%\end{verbatim}
% \end{quote}
