+%
+% \maketitle
+%
+% \begin{abstract}
+% The \LaTeX\ package addresses packages that are dealing with
+% references to titles (\cs{section}, \cs{caption}, \dots).
+% The package tries to remove \cs{label} and other
+% commands from title strings.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% \subsection{Macros}
+%
+% \begin{declcs}{GetTitleStringSetup} \M{key value list}
+% \end{declcs}
+% The options are given as comma separated key value pairs.
+% See section \ref{sec:options}.
+%
+% \begin{declcs}{GetTitleString} \M{text}\\
+% \cs{GetTitleStringExpand} \M{text}\\
+% \cs{GetTitleStringNonExpand} \M{text}
+% \end{declcs}
+% Macro \cs{GetTitleString} tries to remove unwanted stuff from \meta{text}
+% the result is stored in Macro \cs{GetTitleStringResult}.
+% Two methods are available:
+% \begin{description}
+% \item[\cs{GetTitleStringExpand}:]
+% The \meta{text} is expanded in a context where the unwanted
+% macros are redefined to remove themselves.
+% This is the method used in packages \xpackage{titleref}~\cite{titleref},
+% \xpackage{zref-titleref}~\cite{zref}
+% or class \xclass{memoir}~\cite{memoir}.
+% \cs{protect} is supported, but fragile material might break.
+% \item[\cs{GetTitleStringNonExpand}:]
+% The \meta{text} is not expanded. Thus the removal of unwanted
+% material is more difficult. It is especially removed at the
+% start of the \meta{text} and spaces are removed from the end.
+% Currently only \cs{label} is removed in the whole string,
+% if it is not hidden inside curly braces or part of macro
+% definitions. Thus the removal of unwanted stuff might not be
+% complete, but fragile material will not break.
+% (But the result string can break at a later time, of course).
+% \end{description}
+% Option \xoption{expand} controls which method is used by
+% macro \cs{GetTitleString}.
+%
+% \begin{declcs}{GetTitleStringDisableCommands} \M{code}
+% \end{declcs}
+% The \meta{code} is called right before the
+% text is expanded in \cs{GetTitleStringExpand}.
+% Additional definitions can be given for macros that
+% should be removed.
+% Keep in mind that expansion means that the definitions
+% must work in expandable context. Macros like
+% \cs{@ifstar} or \cs{@ifnextchar} or optional arguments
+% will not work. The macro names in \meta{code} may contain
+% the at sign |@|, it has catcode 11 (letter).
+%
+% \subsection{Options}\label{sec:options}
+%
+% \begin{description}
+% \item[\xoption{expand}:] Boolean option, takes values |true| or |false|.
+% No value means |true|. The option specifies the method to remove
+% unwanted stuff from the title string, see below.
+% \end{description}
+% Options can be set at the following places:
+% \begin{itemize}
+% \item \cs{usepackage}
+% \item Configuration file \xfile{gettitlestring.cfg}.
+% \item \cs{GetTitleStringSetup}
+% \end{itemize}

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

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