%
% \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}

% 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}
