% \begin{abstract}
% This package can be used to attach files to a PDF document.
% It is a further development of Scott Pakin's package
% \xpackage{attachfile} for \pdfTeX. Apart from bug fixes,
% package \xpackage{attachfile2} adds support for \xoption{dvips},
% some new options, gets and writes meta information data about
% the attached files.

% \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,
%    package \xpackage{embedfile} 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 Package \xpackage{embedfile} 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}
%    Until this future becomes true, I provide the intermediate
%    step \xpackage{attachfile2} at its current state.
%    There are many things to do:
%    \begin{itemize}
%    \item Documentation, documentation, \dots
%    \item Improving portability of the Perl script \xfile{pdfatfi.pl}
%          (Windows, non-GNU, \dots).
%    \item Comfortable program for extracting embeddd files.
%    \item Embedding files to the document, see package \xpackage{embedfile}.
%    \item Additionally use featurs of \pdfTeX\ 1.30. With a recent
%          \pdfTeX\ the Perl script step is then obsolete.
%    \item GoToE links.
%    \item Layout of PinPush, especially the tip does not scale well.
%    \item Driver for \xoption{dvipsone}, similar to \xoption{dvips}, changes:
%          \begin{itemize}
%          \item coordinate transformation need to be fixed here,
%                \xfile{hdvipson.def} contains:
%                \begin{quote}
%\begin{verbatim}
%/DvipsToPDF { 65781 div  } def
%/PDFToDvips { 65781 mul } def
%\end{verbatim}
%                \end{quote}
%          \item Syntax for \cs{special}: \xfile{hdvipson.def} contains
%                both \verb|\special{! #1}| and
%                \verb|\special{headertext= #1}|. Are bothe the same?
%          \end{itemize}
%    \item File name conversion, see PDF specification:
%          \begin{quote}
%            \verb|c:\somewhere\foobar.txt| $\rightarrow$
%            \verb|/c/somewhere/foobar.txt|
%          \end{quote}
%    \item Option \xoption{scale} for icons?
%    \item Compatibility for \plainTeX.
%    \item ToDos for \xfile{atfidvips.def}.
%    \end{itemize}
%
% \subsection{User interface}
%
%    Basically this package \xpackage{attachfile2} follows the
%    user interface of package \xpackage{attachfile},
%    look into its documentation (\cite{attachfile}).
%
% \subsubsection{New options}
%    \begin{itemize}
%    \item Driver options \xoption{dvips}, \xoption{pdftex},
%          \xoption{dvipdfmx} and \xoption{xetex} that is an
%          alias for \xoption{dvipdfmx}.
%    \item Option \xoption{driverfallback} specifies a DVI driver
%          if the driver cannot be detected automatically.
%    \item New options \xoption{final} and \xoption{draft}.
%    \item New option \xoption{scale} for scaling the annotation rectangle.
%    \item Options \xoption{file} and \xoption{nofile} for controlling
%          the generation of the auxiliary file \xfile{.atfi}.
%    \item New option \xoption{ucfilespec} for file names with
%          characters outside ASCII (PDF 1.7).
%    \end{itemize}
%
% \subsubsection{Option \xoption{color}}
%
%    Package \xpackage{attachfile}'s option \xoption{color} only
%    understands explicit RGB values as three space separated
%    real numbers in the range from 0 to 1.
%
%    This package \xpackage{attachfile2} extends the syntax.
%    The usual color specifications of packages \xpackage{color}
%    or \xpackage{xcolor} may be used. The latter one requires
%    that package \xpackage{xcolor} is loaded.
%    Without package \xpackage{xcolor} a limited range of
%    explicit color specifications are supported, the color models
%    \texttt{rgb} and \texttt{gray} (and \texttt{cmyk} if
%    package \xpackage{hyperref}'s option \xoption{pdfversion} is set
%    to \texttt{1.7} or greater.
%
%    Example without package \xpackage{xcolor}:
%\begin{quote}
%\begin{verbatim}
%\documentclass{article}
%\usepackage[color={1 0 .5}]{attachfile2}
% % Spaces in option values in \usepackage or \documentclass
% % must be protected by curly braces. Otherwise LaTeX strips
% % the spaces and the package would see `color=10.5'.
% % This protection is not necessary for \attachfilesetup.
%\attachfilesetup{color=1 0 .5}
%\attachfilesetup{color=[rgb]{1,0,.5}}
%\attachfilesetup{color=[gray]{.5}}
%\end{verbatim}
%\end{quote}
%
%    The following example with package \xpackage{xcolor} shows
%    additional color specifications:
%\begin{quote}
%\begin{verbatim}
%\documentclass{article}
%\usepackage{xcolor}
%\definecolor{attachfilecolor}{cmyk}{.1,.2,.3,.4}
%\usepackage{color=red}{attachfile2}
%\attachfilesetup{color=red}
%\attachfilesetup{color=attachfilecolor}
%\end{verbatim}
%\end{quote}
%
% \paragraph{For experts.}%
% If the color is used in annotations, the color is converted
% with the help of package \xpackage{xcolor} to RGB.
% PDF versions 1.7 or later also understand color models Gray and
% CMYK. The PDF version is detected if the experimental
% option \xoption{pdfversion}
% of package \xpackage{hyperref} is used, example:
%\begin{quote}
%\begin{verbatim}
%\documentclass{article}
%\usepackage[pdfversion=1.7]{hyperref}
%\usepackage{attachfile2}
%\end{verbatim}
%\end{quote}
% However, currently only driver \xoption{pdftex} also supports
% the actual setting of the PDF version in the output PDF file.
%
% \subsubsection{Perl script \xfile{pdfatfi.pl}}
%
%    This package also tries to get and add meta information data,
%    such as file size, file date, checksum, \dots.
%    As package \xpackage{embedfile} shows the new features
%    of \pdfTeX\ 1.30 are very useful for getting this kind of
%    data. Since version 2.6 these data are used if available.
%
%    For older versions of \pdfTeX\ and \XeTeX\ the Perl script
%    \xfile{pdfatfi.pl} is provided to get this data.
%    The use of the Perl script is not mandatory. This data can be shown
%    by PDF viewers, but they are not a requirement of the PDF specification.
%
%    Package \xpackage{attachfile2} and the Perl script communicate
%    via an auxiliary file with file extension \xfile{.atfi}. The script
%    is used between two \LaTeX\ runs and updates the auxiliary file,
%    example for \xoption{dvips}:
%    \begin{quote}
%\begin{verbatim}
%latex test
%pdfatfi test
%latex test
%dvips test
%ps2pdf test.ps test.pdf
%\end{verbatim}
%    \end{quote}
%
% \subsection{Changes to \xpackage{attachfile}}
%
%    Some of the changes I can remember:
%    \begin{itemize}
%    \item Support for dvips.
%    \item Support for dvipdfmx/\XeTeX.
%    \item Setting and filling the /Param entry for files
%          (file date, file size, \dots).
%    \item Perl script \xfile{pdfatfi.pl}.
%    \item New options.
%    \item Bug fixes.
%    \item \dots
%    \end{itemize}

.SH NAME
pdfatfi \- Help program for the LaTeX package attachfile2.
.SH SYNOPSIS
pdfatfi <command> [<options>] <file[.atfi]>]
.SH DESCRIPTION
Helper program for the LaTeX package attachfile2.

This package also tries to get and add meta information data,
such as file size, file date, checksum, ....

The script pdfatfi.pl is provided for use with old versions of
pdfTeX and XeTeX that do not provide access
to  file metadata.

The use of the Perl script is not mandatory. This data can be shown
by PDF viewers, but they are not a requirement of the PDF specification.

Package attachfile2 and the Perl script communicate
via an auxiliary file with file extension .atfi. The script
is used between two LaTeX runs and updates the auxiliary file.

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\CTANpkg{attachfile2}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/attachfile2/attachfile2.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/attachfile2/attachfile2.pdf}] Documentation.
% \end{description}
%
%
% \paragraph{Bundle.} All the packages of the bundle `attachfile2'
% 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/attachfile2.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{attachfile2.tds.zip} in the
% TDS tree (also known as \xfile{texmf} tree) of your choice.
% Example (linux):
% \begin{quote}
%   |unzip attachfile2.tds.zip -d ~/texmf|
% \end{quote}
%
% \paragraph{Script installation.}
% Check the directory \xfile{TDS:scripts/attachfile2/} 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/attachfile2/pdfatfi.pl|\\
%   |cp scripts/attachfile2/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 attachfile2.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):

% \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
% (\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{Script installation}
%    This package comes with a Perl script \xfile{pdfatfi.pl}.
%    Install it somewhere so that it is executed, when it is called
%    as \verb|pdfatfi| on the command line. Example for
%    installing it under Linux:
%    \begin{quote}
%\begin{verbatim}
%cp pdfatfi.pl /usr/local/bin/pdfatfi
%chmod +x /usr/local/bin/pdfatfi
%\end{verbatim}
%    \end{quote}
%
%
% \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{attachfile2.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 attachfile2.dtx
%makeindex -s gind.ist attachfile2.idx
%pdflatex attachfile2.dtx
%makeindex -s gind.ist attachfile2.idx
%pdflatex attachfile2.dtx
%\end{verbatim}
% \end{quote}
