%
% \begin{abstract}
% This package implements a new bookmark (outline) organization for
% package \xpackage{hyperref}. Bookmark properties such
% as style and color can now be set. Other action types
% are available (URI, GoToR, Named). The bookmarks are
% generated in the first compile run. Package \xpackage{hyperref}
% uses two runs.
% \end{abstract}
%
% \tableofcontents
%
% \section{Documentation}
%
% \subsection{Introduction}
%
% This package \xpackage{bookmark} tries to provide a more modern
% management for bookmarks:
% \begin{itemize}
% \item The bookmarks are already generated in the first \hologo{TeX} compile run.
% \item The font style and color of the bookmarks can be changed.
% \item More actions than simple GoTo actions are possible.
% \end{itemize}
%
% In the same way as \xpackage{hyperref} \cite{hyperref}
% the bookmarks are generated
% in the order of the bookmark generating macros (\cs{bookmark}).
% A level number is used to define the tree structure of the bookmarks.
% The restrictions are less strict:
% \begin{itemize}
% \item The level values may jump and omit values. A \cs{subsubsection}
%       may follow a \cs{chapter}. This was an error in \xpackage{hyperref},
%       that prints a warning and tries to fix this.
% \item Several bookmarks may point to the same destination.
%       In \xpackage{hyperref} this would mess up the bookmark tree
%       completely, because the algorithm assumes that the destination
%       names are keys (unique).
% \end{itemize}
%
% Note that this package is intended as experimentation platform
% for bookmark management. Feedback is welcome. Also the interfaces
% may change in future versions.
%
% \subsection{Options}
%
% Options can be given at four places:
% \begin{enumerate}
% \item \cs{usepackage}|[|\meta{options}|]{bookmark}|\\
%       This is the only place for driver options
%       and option \xoption{atend}.
% \item \cs{bookmarksetup}|{|\meta{options}|}|\\
%       This command is just for setting options.
% \item \cs{bookmarksetupnext}|{|\meta{options}|}|\\
%       The options are stored and called after the
%       options of the next \cs{bookmark} command.
% \item \cs{bookmark}|[|\meta{options}|]{|\meta{title}|}|\\
%       This command sets the bookmark. The option settings remain
%       limited to this bookmark.
% \end{enumerate}
% Exception: Driver options, option \xoption{atend} and
% options \xoption{draft}\slash\xoption{final}
% cannot be changed after the package is loaded.
%
% \subsubsection{Options \xoption{draft} and \xoption{final}}
%
% If a \LaTeX\ file is compiled several times, then a little
% time can be saved, if option \xoption{draft} is used to
% disable the bookmark stuff of this package. Default is
% \xoption{final}.
% Both options are boolean options, without
% value the value |true| is used. |draft=true| is the same
% as |final=false|.
%
% Options of package \xpackage{bookmark} are local options
% with the exception of driver options. Therefore \xoption{draft}
% or \xoption{final} given as class option is not seen by this
% package. If you want to optimize first \LaTeX\ runs depending
% on a global \xoption{draft}, then package \xpackage{ifdraft}
% and \LaTeX's \cs{PassOptionsToPackage}
% might help in the organization of the preamble, for example:
%\begin{quote}
%\begin{verbatim}
%\documentclass[draft]{article}
%\usepackage{ifdraft}
%\ifdraft{%
%   \PassOptionsToPackage{draft}{bookmark}%
%}{}
%\end{verbatim}
%\end{quote}
%
% \subsubsection{Driver options}
%
% Supported drivers are \xoption{pdftex}, \xoption{dvips},
% \xoption{dvipsone}, \xoption{textures},
% \xoption{dvipdfm} (\xoption{xetex}), and \xoption{vtex}.
% The \hologo{TeX} engines \hologo{pdfTeX}, \hologo{XeTeX},
% and \hologo{VTeX} are automatically detected.
% The default for the DVI drivers is \xoption{dvips}. This can
% be changed in the configuration file \xfile{bookmark.cfg} by
% \cs{BookmarkDefaultDriver}, e.g.:
% \begin{quote}
% |\def\BookmarkDefaultDriver{dvipdfm}|
% \end{quote}
%
% \paragraph{Open bookmarks with dvipdfmx.} Since 2007-04-25 the
% cvs version of dvipmdfmx contains a patch that extends the
% \cs{special} for bookmarks in order to specify the open status of
% an outline entry. Option \xoption{dvipdfmx-outline-open} notifies
% the package that the dvi driver program understands this kind
% of \cs{special}. Alternatively \cs{SpecialDvipdfmxOutlineOpen}
% can be defined as number one in the configuration file or before
% the package is loaded, e.g.:
% \begin{quote}
% |\chardef\SpecialDvipdfmxOutlineOpen=1\relax|
% \end{quote}
%
% \subsubsection{Layout options}
%
% \paragraph{Font options.}
%
% \begin{description}
% \item[\xoption{bold}:] The bookmark is shown with a bold font
%   if the PDF viewer supports this (since PDF 1.4).
% \item[\xoption{italic}:] An italic font is used (since PDF 1.4).
% \end{description}
% Both \xoption{bold} and \xoption{italic} can be used together.
% Using value |false| disables the font option.
%
% \paragraph{Color option.}
%
% Colored bookmarks are a feature of PDF 1.4, they are not supported
% by all PDF viewers.
% \begin{description}
% \item[\xoption{color}:] Here the color can be given as
%   color specification of packages \xpackage{color} or \xpackage{xcolor}.
%   An empty value means that the color property is not set.
%   Without package \xpackage{xcolor} the recognized values
%   are restricted to
%   \begin{itemize}
%   \item Empty value, no color is set,\\
%         example: |color={}|
%   \item Explicit color specification of color model rgb,\\
%         example for red: |color=[rgb]{1,0,0}|
%   \item Explicit color specification of color model gray,\\
%         example for dark gray: |color=[gray]{0.25}|
%   \end{itemize}
%   Note that this restriction also holds if package \xpackage{color}
%   is loaded. With \xpackage{xcolor}, however, the full range
%   of color specifications can be used.
% \end{description}
%
% \subsubsection{Action options}
%
% \begin{description}
% \item[\xoption{dest}:] Destination name.
% \item[\xoption{page}:] Page number, first page is 1.
% \item[\xoption{view}:] View specification, examples:\\
%   |view={FitB}|, |view={FitH 842}|, |view={XYZ 0 100 null}|
%   Some view specification parameters expect numbers as parameters
%   with unit bp. They can be given either as plain numbers or
%   as length expressions inside \cs{calc}. Expressions of
%   package \xpackage{calc} are supported if the package is loaded.
%   Otherwise \hologo{eTeX}'s \cs{dimexpr} is used. Example:\\
%   |view={FitH \calc{\paperheight-\topmargin-1in}}|\\
%   |view={XYZ 0 \calc{\paperheight} null}|\\
%   Note that \cs{calc} cannot be used for the third parameter
%   of |XYZ|. This parameter is the zoom value, not a length.
% \item[\xoption{named}:] Named action name:\\
%   |FirstPage|, |LastPage|, |NextPage|, |PrevPage|
% \item[\xoption{gotor}:] Name of the external PDF file.
% \item[\xoption{uri}:] URI specification.
% \item[\xoption{rawaction}:] Raw action specification.
%   Because these specification depends on the driver this option
%   should not be used.
% \end{description}
% The appropriate action for the bookmark is selected by
% analyzing the specified options. The actions
% are distinguished by different sets of options:
% \begin{quote}
% \begin{tabular}{@{}ll@{}}
%   \textbf{Action} & \textbf{Options}\\
%   \hline
%   \textsf{GoTo}: & \xoption{dest}\\
%   \textsf{GoTo}: & \xoption{page} + \xoption{view}\\
%   \textsf{GoToR}: & \xoption{gotor} + \xoption{dest}\\
%   \textsf{GoToR}: & \xoption{gotor} + \xoption{page} + \xoption{view}\\
%   \textsf{Named}: & \xoption{named}\\
%   \textsf{URI}: & \xoption{uri}
% \end{tabular}
% \end{quote}
%
% \paragraph{Missing actions.}
% If the action is missing package \xpackage{bookmark} throws
% an error message. Depending on the driver (\xoption{pdftex},
% \xoption{dvips} and friends) the package detects it quite late
% at the end of the document. Since version 2011/04/21 v1.21
% the package tries printing the line number and file name
% of the corresponding occurence of \cs{bookmark}.
% However, \hologo{TeX} does provide the line number, but
% unhappily the file name is a secret. The package supports
% some ways to get the file name:
% \begin{itemize}
% \item If \hologo{LuaTeX} (indenpendently from DVI or PDF modus)
%   is running, then its |status.filename| is used automatically.
% \item Package \cs{currfile} \cite{currfile} redefines \hologo{LaTeX}
%    internals to keep track of the file name. If the package
%    is loaded, then its \cs{currfilepath} is detected and used
%    automatically by package \xpackage{bookmark}.
% \item The file name can be set manually by option \xoption{scrfile}
%    in \cs{bookmarksetup} or \cs{bookmark}. But be careful,
%    manual setting disables the previous ways for file name
%    detection. And a wrong or missed file name setting might
%    get you a wrong source location in the error message.
% \end{itemize}
%
% \subsubsection{Level options}
%
% The order of the bookmark entries are defined by the
% appearance order of \cs{bookmark} commands. The tree structure
% is constructed by the property \xoption{level} of the bookmark nodes.
% The values of \xoption{level} are integers. If the level of a
% bookmark entry has a higher value than the previous node, then
% the entry becomes a child of the previous node. The absolute
% value of the difference does not matter.
%
% Package \xpackage{bookmark} remembers the level of the previous
% bookmark entry in a global property `current level'.
%
% The behaviour of the level system can be configured by following
% options:
% \begin{description}
% \item[\xoption{level}:]
%    Sets the level, see the description above. If option \xoption{level}
%    is given without value, then the default behaviour is restored,
%    that the `current level' is used as level value.
%    Since version 2010/10/19 v1.16 package \xpackage{bookmark}
%    also supports names |part|, |section| and other,
%    if the macros \cs{toclevel@part}, \cs{toclevel@section}
%    are defined (done by package \xpackage{hyperref}, see
%    option \xoption{bookmarkdepth}).
% \item[\xoption{rellevel}:]
%    Sets the level relative to the previous level.
%    A positive value means that the bookmark entry become
%    a child of the previous one.
% \item[\xoption{keeplevel}:]
%    Use the level, set by \xoption{level} or \xoption{rellevel},
%    but do not change the global property `current level'.
%    The option can be disabled by setting to |false|.
% \item[\xoption{startatroot}:]
%    At this time the bookmark tree starts at the top level again.
%    The next bookmark entry is not sorted as child to a previous entry.
%    Example scenario: A document uses part. However there are
%    last chapters that should not be put below the last part:
%    \begin{quote}
%\begin{verbatim}
%\documentclass{book}
%[...]
%\begin{document}
%  \part{First part}
%    \chapter{First chapter in first part}
%    [...]
%  \part{Second part}
%    \chapter{First chapter in second part}
%    [...]
%  \bookmarksetup{startatroot}
%  \chapter{Index}% does not belong to second part
%\end{document}
%\end{verbatim}
%    \end{quote}
% \end{description}
%
% \subsubsection{Style definitions}
%
% A style is a group of option settings. It can be defined
% by macro \cs{bookmarkdefinestyle} and is used by option \xoption{style}.
% \begin{declcs}{bookmarkdefinestyle} \M{name} \M{key value list}
% \end{declcs}
% The \meta{key value list} of option settings is assigned the
% style \meta{name}.
%
% \begin{description}
% \item[\xoption{style}:]
%   The value of option \xoption{style} is the name of a previously
%   defined style. Its option settings are now executed.
%   The options may include option \xoption{style}.
%   Endless recursion by calling the same style recursively
%   is prevented and throws an error.
% \end{description}
%
% \subsubsection{Hook support}
%
% A hook is called right after the processing the optional options
% of macro \cs{bookmark}.
% \begin{description}
% \item[\xoption{addtohook}:]
%   Code, given as value to this option is added to the hook.
% \end{description}
%
% \begin{declcs}{bookmarkget} \M{option}
% \end{declcs}
% Macro \cs{bookmarkget} extracts the value of the latest option
% setting of option \meta{option}. In case of boolean options number
% one is returned, if the boolean option is enabled, otherwise the
% result is zero.
% The resulting numbers can directly be used in \cs{ifnum} or \cs{ifcase}.
% If you want to have the digits \texttt{0} and \texttt{1}, then
% prefix \cs{bookmarkget} with \cs{number}.
% Macro \cs{bookmarkget} is expandable.
% In case of
% unsupported options an empty string is returned.
% Supported boolean options are
% \begin{quote}
%   \xoption{bold},
%   \xoption{italic},
%   \xoption{open}
% \end{quote}
% Other supported options:
% \begin{quote}
%   \xoption{depth},
%   \xoption{dest},
%   \xoption{color},
%   \xoption{gotor},
%   \xoption{level},
%   \xoption{named},
%   \xoption{openlevel},
%   \xoption{page},
%   \xoption{rawaction},
%   \xoption{uri},
%   \xoption{view},
% \end{quote}
% Additionally the following key is available:
% \begin{quote}
%   \xoption{text}
% \end{quote}
% It returns the text of the outline entry.
%
% \paragraph{Option setting.}
% Inside the hook an option can be set using \cs{bookmarksetup}.
%
% \subsection{Compatibility with \xpackage{hyperref}}
%
% Package \xpackage{bookmark} automatically disables
% \xpackage{hyperref}'s bookmarks. However the package
% uses some of the code of \xpackage{hyperref}. For example,
% the package redefines the hook \cs{Hy@writebookmark} that
% \xpackage{hyperref} inserts in \cs{addcontentsline} and
% other commands. Therefore
% \xpackage{hyperref}'s bookmarks should not be disabled.
%
% Package \xpackage{bookmark} uses \xpackage{hyperref}'s \cs{pdfstringdef}
% and does not provide a replacement.
%
% Some options of \xpackage{hyperref} are also implemented
% in package \xpackage{bookmark}:
% \begin{quote}
% \begin{tabular}{@{}ll@{}}
%   \xpackage{hyperref} & \xpackage{bookmark}\\
%   \hline
%   \xoption{bookmarksdepth} & \xoption{depth}\\
%   \xoption{bookmarksopen} & \xoption{open}\\
%   \xoption{bookmarksopenlevel} & \xoption{openlevel}\\
%   \xoption{bookmarksnumbered} & \xoption{numbered}\\
% \end{tabular}
% \end{quote}
%
% The following commands are also available:
% \begin{quote}
%   \cs{pdfbookmark}\\
%   \cs{currentpdfbookmark}\\
%   \cs{subpdfbookmark}\\
%   \cs{belowpdfbookmark}
% \end{quote}
%
% \subsection{Adding bookmarks at the end}
%
% Package option \xoption{atend} enables the following macro:
% \begin{declcs}{BookmarkAtEnd}
%   \M{stuff}
% \end{declcs}
% Macro \cs{BookmarkAtEnd} puts \meta{stuff} at the end
% of the document. \meta{stuff} means bookmark commands.
% Example:
% \begin{quote}
%\begin{verbatim}
%\usepackage[atend]{bookmark}
%\BookmarkAtEnd{%
%  \bookmarksetup{startatroot}%
%  \bookmark[named=LastPage, level=0]{Last page}%
%}
%\end{verbatim}
% \end{quote}
%
% Alternatively, option \xoption{startatroot} can be given

%
% \paragraph{Remarks.}
% \begin{itemize}
% \item
%   \cs{BookmarkAtEnd} hides the fact that the method for
%   adding bookmarks at the end of the document depends
%   on the driver.
%
%   Some drivers
%   (\xoption{pdftex}, \xoption{dvips}, \xoption{dvipsone},
%   \xoption{textures}) use package \xpackage{atveryend}'s
%   for this purpose. \cs{AtEndDocument} is too early,
%   the last page might not been shipped out. Because the \xext{aux}
%   file is needed, these drivers use \cs{AfterLastShipout}.
%
%   The implementation of the other drivers
%   (\xoption{dvipdfm}, \xoption{xetex}, \xoption{vtex})
%   depends on
%   \cs{special} that does not have an effect after the last
%   page. In this case \cs{AtEndDvi} of package \xpackage{atenddvi}
%   helps. It puts its argument on last page of the document.
%   Two \hologo{LaTeX} runs are necessary at least, because
%   the last page is detected by a reference.
% \item
%   The time of expansion of the argument of \cs{BookmarkAtEnd}
%   is not specified. This can happen immediately or at the end
%   of the document.
% \end{itemize}
%
% \subsection{Limitations/ToDos}
%
% \begin{itemize}
% \item Support for missing actions (Launch, \dots).
% \item Better design for \xpackage{hyperref}'s option
%       \xoption{bookmarkstype}.
% \end{itemize}

%    \xext{aux} file.
%    \begin{itemize}
%    \item
%      Driver \xoption{pdftex} uses \cs{pdfoutline} that can
%      be used after the last page.
%    \item
%      PostScript drivers such as
%      \xoption{dvips} use an external PostScript header file
%      for the bookmarks. File writing can be done after
%      the last shipout page, but before the \xext{aux} file is closed.

%    The other drivers implement \cs{bookmark} using \cs{special}
%    commands. Thus the last bookmarks must be put on the last page,
%    not afterwards.
%    \cs{AtEndDocument} cannot be used, because it is too late, the
%    last page can already be output. Therefore we use package
%    \xpackage{atenddvi} that uses the help of packages \xpackage{atbegshi}
%    and \xpackage{zref}. The argument of \cs{AtEndDvi} is put
%    at the end of the last page. At least two \hologo{LaTeX} runs are necessary.
%    \begin{macrocode}
%<*dvipdfm|vtex>

  \RequirePackage{atenddvi}%
  \AtEndDvi{\BKM@EndHook}%

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\url{http://ctan.org/pkg/bookmark}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/bookmark.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/bookmark.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 bookmark.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
% (\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 bookmark.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{bookmark.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 bookmark.dtx
%makeindex -s gind.ist bookmark.idx
%pdflatex bookmark.dtx
%makeindex -s gind.ist bookmark.idx
%pdflatex bookmark.dtx
%\end{verbatim}
% \end{quote}

    This package implements a new bookmark (outline) organization for
    package <xref refid='hyperref'>hyperref</xref>. Bookmark properties such
    as style and color can now be set. Other action types
    are available (URI, GoToR, Named). The bookmarks are
    generated in the first compile run. Package
    <xref refid='hyperref'>hyperref</xref> uses two runs.
    <p/>
    The package is part of the <xref refid='oberdiek'>oberdiek</xref>
    bundle.
