+% \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 (8-bit, path separators, \dots), look into
+% the PDF specification (\cite{pdfspec}).
+% There are rules how these file names must be written/encoded.
+% Avoid 8-bit characters
+% and other special characters, the behaviour is currently undefined.
+% Use option \xoption{ucfilespec} for more funny file names.
+% The string method, see below, is |escape| since version 2.4.
+%
+% This name is also used as entry in a name tree
+% (see PDF specification: |/EmbeddedFiles|). Therefore the
+% value for \xoption{filespec} must be unique among all
+% embedded files. Also key \xoption{initialfiles} refers
+% to this name, if the file name and the value of \xoption{filespec}
+% are different.
+% \item[\xoption{ucfilespec}]
+% Since PDF 1.7 the file name may be provided in Unicode.
+% The conversion of the option value into a PDF string
+% is controlled by option \xoption{stringmethod}.
+% \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{ucfilespec}
+% and \xoption{desc} into a PDF string (before version 2.4: \xoption{filespec}
+% and \xoption{desc}). 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}.
+% \item[\xoption{\meta{key}.value}] Sets the value of a collection
+% item property, see section \ref{sec:collection}.
+% \item[\xoption{\meta{key}.prefix}]
+% Sets the prefix of a collection item property,
+% see section \ref{sec:collection}.
+% \item[\xoption{id}]
+% The value must be an unique name. Macros
+% \cs{embedfileifobjectexists} and \cs{embedfilegetobject}
+% are using this name later.
+% \end{description}
+%
+% \begin{declcs}{embedfilefinish}
+% \end{declcs}
+% The list of all embedded files must be added as data structure
+% in the PDF file. In case of \LaTeX\ this is automatically done.
+% The package uses \cs{AtEndDocument}. Then the list of all
+% files should be known. However, \plainTeX\ does not know
+% about \cs{AtEndDocument}. Thus the user must call
+% \cs{embedfilefinish} at the end of the document
+% after the last file is embedded.
+%
+% \begin{declcs}{embedfilesetup} \M{options}
+% \end{declcs}
+% Options for \cs{embedfile} and collection support
+% can be set in \cs{embedfilesetup}.
+%
+% \subsection{Collection support (PDF 1.7)}
+% \label{sec:collection}
+%
+% Since PDF 1.7 the embedded files can form a \emph{collection}
+% (sometimes referred as \emph{package}), the main document
+% is called \emph{cover sheet}. See PDF specification
+% 8.2.4 ``Collections'' and 3.10.5 ``Collection items'' \cite{pdfspec}.
+%
+% Usually Acrobat Reader 7 or 8 shows the
+% embedded files in a table at the bottom with the following columns:
+% \begin{quote}
+% \begin{tabular}{@{}l|l|l|l@{}}
+% Name & Description & Modified & Size\\
+% \hline
+% \dots & \dots & \dots & \dots\\
+% \end{tabular}
+% \end{quote}
+% Acrobat Reader 10 shows the embeded files in the left panel
+% and adds a new column for the compressed size.
+%
+% If the files form a collection, then they are displayed
+% in a table left or top (depending on option \xoption{view},
+% see \cs{embedfilesetup}).
+%
+%
+% Collection support is enabled automatically, if
+% it is used.
+%
+% \begin{declcs}{embedfilesetup} \M{options}
+% \end{declcs}
+% The following options are supported in addition
+% to options for \cs{embedfile}:
+% \begin{description}
+% \item[\xoption{view}]
+% If the PDF file contains a collection, then Acrobat Reader 8
+% shows a line at the top below the menu bar and the toolbar.
+% It shows the current selected file, icons for changing the
+% view mode, an options menu.
+% The initial mode how the collection is presented is
+% set by this option \xoption{view}.
+% The following modes/values are supported, the default is |details|:
+% \begin{description}
+% \item[\texttt{details}] The full collection table is displayed
+% at the top below the collection bar.
+% \item[\texttt{tile}] The files of the collection are shown
+% in tile mode on the left.
+% \item[\texttt{hidden}] The collection table is not shown.
+% \end{description}
+% \item[\xoption{initialfile}]
+% Selects the file that is initially presented. Especially
+% useful for an embedded PDF file that is then shown instead
+% of the cover document. There must be an \cs{embedfile} command
+% somewhere whose value for key \xoption{filespec} is used here.
+% The \cs{embedfile} command can drop option \xoption{filespec}
+% if the file name is not different.
+% \end{description}
+%
+% \begin{declcs}{embedfilefield} \M{key} \M{options}
+% \end{declcs}
+% Macro \cs{embedfilefield} defines a column/field in the collection table.
+% The name of the field is \meta{key}.
+% \begin{description}
+% \item[\xoption{type}]
+% sets the type of the field. The supported values are:
+% \begin{description}
+% \item[\texttt{text}] A text field. Its value is set in
+% \cs{embedfile} by option \xoption{\meta{key}.value}.
+% \item[\texttt{date}] A date field. Its value is set in
+% \cs{embedfile} by option \xoption{\meta{key}.value}.
+% A special format is required, see ``3.8.3 Dates'' \cite{pdfspec}.
+% \item[\texttt{number}] A field with an integer or float number.
+% Its value is set in \cs{embedfile} by option
+% \xoption{\meta{key}.value}.
+% \item[\texttt{file}] The file name of the embedded file.
+% \item[\texttt{desc}] The description text of the embedded file. It is
+% set in \cs{embedfile} by option \xoption{desc}.
+% \item[\texttt{moddate}] The modification date of the embedded file.
+% \item[\texttt{size}] The size of the embedded file.
+% \end{description}
+% All types allow the use of a prefix that is disregarded by
+% sorting. The prefix for this field is set in \cs{embedfile} by
+% option \xoption{\meta{key}.prefix}.
+% \item[\xoption{title}] sets the column title.
+% \item[\xoption{visible}] controls whether the column is presented:
+% \begin{description}
+% \item[\texttt{true}] shows the column.
+% \item[\texttt{false}] hides the column.
+% \end{description}
+% Default: \texttt{true}
+% \item[\xoption{edit}]
+% Allows the editing of field values. Does not seem to have an
+% effect for Acrobat Reader.
+% \begin{description}
+% \item[\texttt{true}] enables the feature, if available (depends
+% on the PDF viewer).
+% \item[\texttt{false}] disables the feature.
+% \end{description}
+% Default: \texttt{false}
+% \end{description}
+% The order of \cs{embedfilefield} statements defines the order
+% of the columns.
+%
+% \begin{declcs}{embedfilesort} \M{key-sort-list}
+% \end{declcs}
+% The sort order of the embedded files are controlled by
+% macro \cs{embedfilesort}. \meta{key-sort-list} defines
+% the sort order. The key is a field name defined by \cs{embedfilefield}.
+% Its value is either \texttt{ascending} or \texttt{descending}.
+% The default is \texttt{ascending}.
+%
+% \subsection{Export of object references}
+%
+% Caution: This feature is still experimental. It may be even removed
+% in future versions. Therefore feedback would be nice, if someone
+% has a useful application for this feature.
+%
+% Object numbers are saved, if \xoption{id} is given in \cs{embedfile}.
+% The following objects are supported:
+% \begin{itemize}
+% \item \texttt{EmbeddedFile}
+% \item \texttt{Filespec}
+% \end{itemize}
+%
+% \begin{declcs}{embedfileifobjectexists} \M{id} \M{type}
+% \M{then} \M{else}
+% \end{declcs}
+% Macro \cs{embedfileifobjectexists} tests whether object of \meta{type}
+% is available for the embedded file identified by \meta{id}.
+%
+% \begin{declcs}{embedfilegetobject} \M{id} \M{type}
+% \end{declcs}
+% Macro \cs{embedfilegetobject} expands to the full object reference
+% object of \meta{type} for the embedded file identified by \meta{id}.
+%
+% \subsubsection{Example}
+%
+%\begin{quote}
+%\begin{verbatim}
+%\embedfile[id={foo}]{foo.pdf}
+%\embedfileifobjectexists{foo}{Filespec}{%
+% \typeout{%

+% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{embedfile}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/embedfile/embedfile.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/embedfile/embedfile.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `embedfile'
+% 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[\CTANinstall{install/macros/latex/contrib/embedfile.tds.zip}]
+% \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{embedfile.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+% |unzip embedfile.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 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):

+% 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{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}
