%
% \begin{abstract}
% This package adds hyper features to the package
% \xpackage{doc} that is used in the documentation
% system of \LaTeXe. Bookmarks are added and references
% are linked as far as possible.
% \end{abstract}
%
% \tableofcontents
%
% \section{Features}
%
% The package adds the following features:
% \begin{description}
% \item[Bookmarks:]
%   For supporting bookmarks package \verb|hyperref| is loaded.
%   Some \TeX\ code inside section titles can cause problems
%   during bookmark processing; these can be warnings, ugly
%   bookmark titles or even errors. With the help of
%   \verb|\pdfstringdefDisableCommands| or \verb|\texorpdfstring|
%   you can manage these things, see \verb|hyperref|'s package
%   documentation.
% \item[Additional bookmarks:]
%   Unnumbered bookmark entries are generated for:
%   \begin{itemize}
%   \item Table of contents
%   \item List of figures
%   \item List of tables
%   \item Index
%   \item Glossary
%   \end{itemize}
%   Option \texttt{numbered} controls, whether these section or
%   chapters should be numbered. The exception is the table
%   of contents if this it would be the first numbered
%   section. Then just a bookmark is added.
% \item[Metadata:]
%   The loaded package \verb|hyperref|, enforced by
%   option \verb|pdfusetitle|, tries to detect \verb|\title|
%   and \verb|\author| and sets the corresponding PDF
%   information fields. In case of problems see the previous
%   item about bookmarks.
%   These enries can be overwritten or new ones added by
%   \verb|\hypersetup| after the packages is loaded, see
%   documentation of package \verb|hyperref|.
% \item[References, links:] Because of package \verb|\hyperref|
%   |\ref| become links, also \verb|\url|, footnote referencing
%   are supported.
% \item[Index:]
%   The main part of this package deals with index links in order
%   to support the kind of index that package \verb|doc| provides.
% \item[Thumbnails:]
%   Package \verb|thumbpdf| is loaded for the case that the
%   PDF file also should contain thumbnails, see the documentation
%   of this package. But thumbnail embedding is not really
%   necessary, because nowadays AcrobatReader is able to
%   generate and view thumbnails on the fly.
% \end{description}
%
% \section{Usage}
%
% The purpose of this packages is to add PDF features to
% the documentation of LaTeX packages. Thus just load
% the package in the driver file that generates the
% documentation:
% \begin{quote}
%   \verb|\usepackage{hypdoc}|
% \end{quote}
% Package \verb|doc| is loaded by \verb|hypdoc|, thus you
% also can replace a \verb|\usepackage{doc}| with this line.
% At any case, the package must be loaded before macros of
% package \verb|doc| such as \verb|\CodelineIndex| or
% \verb|\PageIndex| are used.
%
% If the class \verb|ltxdoc| is used, you can also use
% the configuration file for this class to add
% package \verb|hypdoc|. Add the following line
% to the file \verb|ltxdoc.cfg| (or create a new one):
% \begin{quote}
%\begin{verbatim}
%\AtEndOfClass{\RequirePackage{hypdoc}}
%\end{verbatim}
% \end{quote}
%
% \subsection{Options}
%
% There is one option \texttt{numbered}. It controls,
% whether the starred versions of section or chapter
% inside \cs{tableofcontents}, \cs{listoffigures}, \dots
% should be replaced by the non-star versions.
%
% \subsection{Simple example}
% Example of a simple driver file \verb|foobar.drv|
% of a package \verb|foobar|. Often the driver file
% is packed in the file \verb|foobar.dtx| and can
% be extracted by docstrip or if an instruction file
% for docstrip is provided by:
% \begin{quote}
% \verb|tex foobar.ins|
% \end{quote}
% Note that although docstrip doesn't rely on \LaTeX,
% sometimes you need to run the \verb|.ins| file through
% \LaTeX. Oddly enough, often the only \LaTeX\ feature
% in use is \verb|\NeedsTeXFormat{LaTeX2e}| in the first line.
% \begin{quote}
%\begin{verbatim}
%\documentclass{ltxdoc}
%\usepackage{hypdoc}
%\RecordChanges
%\EnableCrossrefs
%\CodelineIndex
%\begin{document}
%\title{Title for package \texttt{foobar}}
%\author{Author of package \texttt{foobar}}
%\date{...}
%\maketitle
%\tableofcontents
%\DocInput{foobar.dtx}
%\PrintChanges
%\PrintIndex
%\end{document}
%\end{verbatim}
% \end{quote}
%
% Then compile it, for example with pdf\LaTeX.
% \begin{quote}
%\begin{verbatim}
%pdflatex foobar.drv
%makeindex -s gind.ist foobar.idx
%makeindex -s gglo.ist -o foobar.gls foobar.glo
%pdflatex foobar.drv
%\end{verbatim}
% \end{quote}
% You will need several cycles until the cross references
% and similar things are correct.
%
% \subsection{Example \texttt{source2e.tex}}
%
% The source code of the base of \LaTeX\ is available as
% a bunch of \verb|.dtx| files. \LaTeX\ provides the file
% \verb|source2e.tex| to merge them all together.
%
% Now you can either load package \verb|hypdoc| in a private copy
% of this file (please, respect the LPPL) or use the configuration
% file \verb|ltxdoc.cfg|. Example that also sets A4 paper size:
% \begin{quote}
%\begin{verbatim}
%\PassOptionsToClass{a4paper}{article}
%\AtEndOfClass{\RequirePackage{hypdoc}}
%\end{verbatim}
% \end{quote}
%
% Then \verb|source2e.tex| can be compiled by pdf\TeX, for example:
% \begin{quote}
%\begin{verbatim}
%pdflatex source2e
%makeindex -s gind.ist source2e.idx
%makeindex -s gglo.ist -o source2e.glo source2e.gls
%pdflatex source2e
%makeindex -s gind.ist source2e.idx
%makeindex -s gglo.ist -o source2e.glo source2e.gls
%pdflatex source2e
%\end{verbatim}
% \end{quote}

% \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/hypdoc.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/hypdoc.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 hypdoc.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}
% \def\t{^^A
% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}}

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