% \section{Usage}
%
% \subsection{Bookmarks restrictions}\label{sec:restrictions}
%    Outline entries (bookmarks) are written to a file and have
%    to obey the pdf specification.
%    Therefore they have several restrictions:
%    \begin{itemize}
%    \item Bookmarks have to be encoded in PDFDocEncoding^^A
%          \footnote{\Package{hyperref} doesn't support
%            Unicode.}.
%    \item They should only expand to letters and spaces.
%    \item The result of expansion have to be a valid pdf string.
%    \item Stomach commands like \cmd{\relax}, box commands, math,
%          assignments, or definitions aren't allowed.
%    \item Short entries are recommended, which allow a clear view.
%    \end{itemize}
%
% \subsection{\texorpdfstring{\cmd{\texorpdfstring}}{^^A
%    \textbackslash texorpdfstring}}
%    The generic way in package \Package{hyperref} is the use
%    of \cmd{\texorpdfstring}^^A
%    \footnote{In versions of \Package{hyperref} below 6.54 see
%      \cmd{\ifbookmark}.}:
%    \begin{quote}
%\begin{verbatim}
%\section{Pythagoras:
%  \texorpdfstring{$a^2+b^2=c^2}{%
%    a\texttwosuperior\ + b\texttwosuperior\ =
%    c\texttwosuperior}%
%}
%\end{verbatim}
%    \end{quote}
%
% \subsection{Sectioning commands}
%    The package \Package{hyperref} automatically generates
%    bookmarks from the sectioning commands,
%    unless it is suppressed by an option.
%    Commands that structure the text are here called
%    ``sectioning commands'':
%    \begin{quote}
%    \cmd{\part}, \cmd{\chapter},\\
%    \cmd{\section}, \cmd{\subsection}, \cmd{\subsubsection},\\
%    \cmd{\paragraph}, \cmd{\subparagraph}
%    \end{quote}
%
% \subsection{Places\texorpdfstring{ for sectioning strings}{}}
%    \label{sec:places}
%    The argument(s) of these commands are used on several places:
%    \begin{description}
%    \item[\type{text}]
%      The current text without restrictions.
%    \item[\type{toc}]
%      The headlines and the table of contents with the
%      restrictions of ``moving arguments''.
%    \item[\type{out}]
%      The outlines with many restrictions: The outline
%      have to expand to a valid pdf string with PDFDocEncoding
%      (see \ref{sec:restrictions}).
%    \end{description}
%
% \subsection{\texorpdfstring{Solution with o}{O}ptional arguments}
%    If the user wants to use a footnote within a sectioning command,
%    the \LaTeX{} solution is an optional argument:
%    \begin{quote}
%      |\section[Title]{Title\footnote{Footnote text}}|
%    \end{quote}
%    Now |Title| without the footnote is used in the headlines and
%    the table of contents. Also \Package{hyperref} uses it for the
%    bookmarks.
%
%    This package \Package{\filename} offers two possibilities to
%    specify a separate outline entry:
%    \begin{itemize}
%    \item An additional second optional argument in square brackets.
%    \item An additional optional argument in parentheses (in
%          association with a pdf string that is internally surrounded
%          by parentheses, too).
%    \end{itemize}
%    Because \Package{\filename} stores the original meaning of the
%    sectioning commands and uses them again, there should be no
%    problems with packages that redefine the sectioning commands, if
%    these packages doesn't change the syntax.
%
% \subsection{Syntax}
%    The following examples show the syntax of the sectioning
%    commands. For the places the strings appear the abbreviations
%    are used, that are introduced in \ref{sec:places}.
%
% \subsubsection{\texorpdfstring{Star form}{^^A
%    \textbackslash section*\{\}}}
%    The behaviour of the star form isn't changed. The string
%    appears only in the current text:
%    \begin{article}{Syntax}
%    \begin{quote}
%      |\section*{text}|
%    \end{quote}
%    \end{article}
%
% \subsubsection{\texorpdfstring{Without optional arguments}{^^A
%    \textbackslash section\{\}}}
%    The normal case, the string in the mandatory argument is
%    used for all places:
%    \begin{article}{Syntax}
%    \begin{quote}
%      |\section{text, toc, out}|
%    \end{quote}
%    \end{article}
%
% \subsubsection{\texorpdfstring{One optional argument}{^^A
%    \textbackslash section[]\{\}}}
%    Also the form with one optional parameter in square brackets isn't
%    new; for the bookmarks the optional parameter is used:
%    \begin{article}{Syntax}
%    \begin{quote}
%      |\section[toc, out]{text}|
%    \end{quote}
%    \end{article}
%
% \subsubsection{\texorpdfstring{Two optional arguments}{^^A
%    \textbackslash section[][out]\{\}}}\label{sec:two}
%    The second optional parameter in square brackets is introduced
%    by this package to specify an outline entry:
%    \begin{article}{Syntax}
%    \begin{quote}
%      |\section[toc][out]{text}|
%    \end{quote}
%    \end{article}
%
% \subsubsection{\texorpdfstring{Optional argument in parentheses}{^^A
%    \textbackslash section(out)\{\}}}
%    Often the \type{toc} and the \type{text} string would be the same.
%    With the method of the two optional arguments in square brackets
%    (see \ref{sec:two}) this string must be given twice,
%    if the user only wants to specify a different outline entry.
%    Therefore this package offers another possibility:
%    In association with the internal representation in the pdf file
%    an outline entry can be given in parentheses.
%    So the package can easily distinguish between
%    the two forms of optional arguments and the order does not matter:
%    \begin{article}{Syntax}
%    \begin{quote}
%      |\section(out){toc, text}|\\
%      |\section[toc](out){text}|\\
%      |\section(out)[toc]{text}|
%    \end{quote}
%    \end{article}
%
% \subsection{Without \Package{hyperref}}
%    Package \Package{\filename} uses \Package{hyperref} for support of
%    the bookmarks, but this package is not required.
%    If \Package{hyperref} isn't loaded, or
%    is called with a driver that doesn't support bookmarks,
%    package \Package{\filename} shouldn't be removed,
%    because this would lead to
%    a wrong syntax of the sectioning commands.
%    In any cases package \Package{\filename}
%    supports its syntax and ignores the outline entries,
%    if there are no code for bookmarks.
%    So it is possible to write texts,
%    that are processed with several drivers to get different output
%    formats.
%
% \subsection{Protecting parentheses}
%    If the string itself contains parentheses, they have to be hidden
%    from \TeX's argument parsing mechanism.
%    The argument should be surrounded
%    by curly braces:
%    \begin{quote}
%      |\section({outlines(bookmarks)}){text, toc}|
%    \end{quote}
%    With version 6.54 of \Package{hyperref} the other standard method
%    works, too: The closing parenthesis is protected:
%    \begin{quote}
%      |\section(outlines(bookmarks{)}){text, toc}|
%    \end{quote}
%
% \StopEventually{

%    \item store the sectioning command |#1| in \cmd{\hbs@seccmd}

%          read by \cmd{\hbs@getsquare}
%    \item An optional argument in parentheses is an outline entry.
%          This is worked off by \cmd{\hbs@getbookmark}.
%    \item If there are no more optional arguments, \cmd{\hbs@process}
%          reads the mandatory argument and calls the original

% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\CTANpkg{hypbmsec}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/hypbmsec.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/hypbmsec.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[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
% \end{description}
% \emph{TDS} refers to the standard ``A Directory Structure
% for \TeX\ Files'' (\CTANpkg{tds}). 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}
%
% \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 hypbmsec.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):

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