% \section{Documentation}
%
% \subsection{Introduction}
%
% This package uses a mark register in order to solve the
% problem of a missing color stack of \pdfTeX\ prior 1.40.0.
% Since this version of \pdfTeX\ a color stack is available
% and supported by \xfile{pdftex.def} 2007/01/01 v0.04a.
% In this case this package is obsolete and the package
% stops its loading.
%
% \subsection{Background}
%
% After the Dante meeting (Clausthal 2000) I have started
% to experiment with the eTeX method of a \emph{colour} mark.
% One of the major problems is the understanding of the
% output routine and the need to rewrite it because of
% missing hooks. Currently I have made some tests in
% in onecolumn and twocolumn mode, but the state is
% experimental.
%
% \subsection{Limitations}
%
% \begin{itemize}
% \item Mark limitations: page breaks in math.
% \item \LaTeX's output routine is redefinded.
%   \begin{itemize}
%   \item Changes in the output routine of newer versions
%         of LaTeX are not detected.
%   \item Packages that change the output routine are not
%         supported.
%   \end{itemize}
% \item It does not support several independent text
%       streams like footnotes.
% \item Limitations in float and marginpar support.
% \end{itemize}
%
% \subsection{Recommendation}
%
% \eTeX\ (for additional mark register)
% Without \eTeX\ \LaTeX's mark commands are redefined
% to store an additional color value.
%
% \subsection{Usage}
%
% Load after package color:
% \begin{quote}
%   |\usepackage[pdftex]{color}|\\
%   |\usepackage{pdfcolmk}|
% \end{quote}
%
% \subsection{Compatibility}
%
% \begin{itemize}
% \item Load the following packages after \xpackage{pdfcolmk}:
%   \begin{quote}
%       \xpackage{mparhack.sty}
%   \end{quote}
% \item Load the following packages before \xpackage{pdfcolmk}:
%   \begin{quote}
%       \xpackage{marn.sty}\\
%       \xpackage{newmarn.sty}
%   \end{quote}
% \item Supported \cs{@addmarginpar} patch:
%   \begin{quote}
%       \xpackage{latex/base/latex.ltx}\\
%       \xpackage{memoir.cls}\\
%       \xpackage{poemscol/marn.sty}, \xpackage{poemscol/newmarn.sty}\\
%       \xpackage{mparhack.sty}
%   \end{quote}
% \item Unsupported \cs{@addmarginpar} patch:
%   \begin{quote}
%       \xpackage{lineno.sty}\\
%       \xpackage{sttools/marginal.sty}\\
%       \xpackage{revtex4.cls}
%   \end{quote}

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\url{http://ctan.org/pkg/pdfcolmk}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/pdfcolmk.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/pdfcolmk.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 pdfcolmk.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}

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

% The following XML file can be used as source for the
% \href{http://mirror.ctan.org/help/Catalogue/catalogue.html}{\TeX\ Catalogue}.
% The elements \texttt{caption} and \texttt{description} are imported
% from the original XML file from the Catalogue.
% The name of the XML file in the Catalogue is \xfile{pdfcolmk.xml}.

  <description>
    The package provides macros that emulate the &#x2018;colour stack&#x2019;
    functionality of dvips.  The colour stack deals with colour
    manipulations when asynchronous events (like page-breaking) occur;
    pdftex does not (yet) have such a stack, but dvips does, and the
    <xref refid='color'>color</xref> package makes extensive use of
    it.
    <p/>
    This package is an experimental solution to the problem, and works
    best with pdf-e-tex.
    <p/>
    The package is part of the <xref refid='oberdiek'>oberdiek</xref> bundle.
