% \begin{abstract}
% Package \xpackage{hypdestopt} supports \xpackage{hyperref}'s
% \xoption{pdftex} driver. It removes unnecessary destinations
% and shortens the destination names or uses numbered destinations
% to get smaller PDF files.
% \end{abstract}
%
% \tableofcontents
%
% \section{User interface}
%
% \subsection{Introduction}
%
% Before PDF-1.5 annotations and destinations cannot be compressed.
% If the destination names are not needed for external use, the
% file size can be decreased by the following means:
% \begin{itemize}
% \item Unused destinations are removed.
% \item The destination names are shortened (option \xoption{name}).
% \item Using numbered destinations (option \xoption{num}).
% \end{itemize}
%
% \subsection{Requirements}
%
% \begin{itemize}
% \item Package \xpackage{hyperref} 2006/06/01 v6.75a or newer
%       (\cite{hyperref}).
% \item Package \xpackage{alphalph} 2006/05/30 v1.4 or newer
%       (\cite{alphalph}), if option \xoption{name} is used.
% \item Package \xpackage{ifpdf} (\cite{ifpdf}).
% \item \pdfTeX\ 1.30.0 or newer.
% \item \pdfTeX\ in PDF mode.
% \item \eTeX\ extensions enabled.
% \item Probably an additional compile run of \pdfLaTeX\ is necessary.
% \end{itemize}
%
% In the first compile runs you can get warnings such as:
%\begin{quote}
%\begin{verbatim}
%! pdfTeX warning (dest): name{...} has been referenced ...
%\end{verbatim}
%\end{quote}
% These warnings should vanish in later compile runs.
% However these warnings also can occur without this package.
% The package does not cure them, thus these warnings will remain,
% but the destination name can be different. In such cases test
% without package, too.
%
% \subsection{Use}
%
% If the requirements are met, load the package:
%\begin{quote}
%\verb|\usepackage{hypdestopt}|
%\end{quote}
%
% The following options are supported:
% \begin{description}
% \item[\xoption{verbose}:] Verbose debug output is enabled and written
%   in the protocol file.
% \item[\xoption{num}:] Numbered destinations are used. The file size
%   is smaller, because names are no longer used.
%   This is the default.
% \item[\xoption{name}:] Destinations are identified by names.
% \end{description}
%
% \subsection{Limitations}
%
% \begin{itemize}
% \item Forget this package, if you need preserved destination names.
% \item Destination name strings use all bytes (0..255) except
%       the carriage return (13), left parenthesis (40), right
%       parenthesis (41), and backslash (92), because they
%       must be quoted in general and therefore occupy two bytes
%       instead of one.
%
%       Further the zero byte (0) is avoided for programs
%       that implement strings using zero terminated C strings.
%       And 255 (0xFF) is avoided to get rid of a possible
%       unicode marker at the begin.
%
%       So far I have not seen problems with:
%       \begin{itemize}
%       \item AcrobatReader 5.08/Linux
%       \item AcrobatReader 7.0/Linux
%       \item xpdf 3.00
%       \item Ghostscript 8.50
%       \item gv 3.5.8
%       \item GSview 4.6
%       \end{itemize}
%       But I have not tested all and all possible PDF viewers.
% \item Use of named destinations (\cs{pdfdest}, \cs{pdfoutline},
%       \cs{pdfstartlink}, \dots) that are not supported by this
%       package.
% \item Currently only \xpackage{hyperref} with \pdfTeX\ in PDF
%       mode is supported.
% \end{itemize}
%
% \subsection{Future}
%
% A more general approach is a PDF postprocessor that takes
% a PDF file, performs some transformations and writes the
% result in a more optimized PDF file. Then it does not depend,
% how the original PDF file was generated and further improvements
% are easier to apply. For example, the destination names could be sorted:
% often used destination names would then be shorter than seldom used ones.

% \subsubsection{Options \xoption{num} and \xoption{name}}
%
%    The options \xoption{num} or \xoption{name} specify

%
%    First \pdfTeX\ must running in PDF mode.
%    \begin{macrocode}

%
% \subsection{Preamble for auxiliary file}
%
%    Provide dummy definitions for the macros that are used in the

%
%    \begin{macro}{\HypDest@PrependDocument}
%    We add our stuff in front of the \cs{AtBeginDocument} hook

% \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/hypdestopt.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/hypdestopt.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/oberdiek.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 hypdestopt.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}

% 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 hypdestopt.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{hypdestopt.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 hypdestopt.dtx
%makeindex -s gind.ist hypdestopt.idx
%pdflatex hypdestopt.dtx
%makeindex -s gind.ist hypdestopt.idx
%pdflatex hypdestopt.dtx
%\end{verbatim}
