+% \maketitle
+%
+% \begin{abstract}
+% Since version 1.40 \pdfTeX\ supports several color stacks.
+% This package uses them to fix color problems in
+% package \xpackage{parcolumns}.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Usage}
+%
+% \begin{quote}
+% |\usepackage{pdfcolparcolumns}|
+% \end{quote}
+% The package \xpackage{pdfcolparcolumns} loads package \xpackage{parcolums}
+% \cite{parcolumns}. If color stacks are available then the
+% macros of \xpackage{parcolumns} are patched to add support
+% for color stacks.
+%
+% \subsection{Option \xoption{rulebetweencolor}}
+%
+% Package \xpackage{pdfcolparcolumns} also fixes the color for the
+% rule between columns (if \xoption{rulebetween} is set).
+% Default color is \cs{normalcolor}. But this can be changed by using
+% option \xoption{rulebetweencolor}. It takes a color specification
+% as value. If the value is empty, then the default (\cs{normalcolor})
+% is used.
+% Examples:
+% \begin{quote}
+% |rulebetweencolor=blue|,\\
+% |rulebetweencolor={red}|,\\
+% |rulebetweencolor={}|, \textit{\% \cs{normalcolor} is used}\\
+% |rulebetweencolor=[rgb]{1,0,.5}| \textit{\% see below}
+% \end{quote}
+% If used inside the optional argument of environment \textsf{parcolumns}
+% and the value contains an optional argument, then whole value
+% must be put in curly braces:
+%\begin{quote}
+%\begin{verbatim}
+%\begin{parcolumns}[
+% rulebetween,
+% rulebetweencolor={[rgb]{1,0,.5}},
+%]{2}
+% ...
+%\end{parcolumns}
+%\end{verbatim}
+%\end{quote}
+% This option \xoption{rulebetweencolor} can also be set using
+% \cs{setkeys}:
+%\begin{quote}
+%\begin{verbatim}
+%\setkeys{parcolumns}{rulebetweencolor=green}
+%\end{verbatim}
+%\end{quote}
+%
+% \subsection{Future}
+%
+% Currently package \xpackage{parcolumns} does not seem to be
+% maintained. Nevertheless if there will be a new version that
+% adds support for color stacks, then this package may become
+% obsolete.

+%
+% \subsection{Load packages}
+%
+% \subsubsection{Package \xpackage{parcolumns}}
+%
+% Currently package \xpackage{parcolumns} does not define options.
+% Thus it is just a precaution that the options of
+% package \xpackage{pdfcolparcolumns} are passed to
+% package \xpackage{parcolumns}.
+% \begin{macrocode}
+\DeclareOption*{%
+ \PassoptionsToPackage{\CurrentOption}{parcolumns}%
+}
+\ProcessOptions\relax
+\RequirePackage{parcolumns}[2004/11/25]
+% \end{macrocode}
+%
+% \subsubsection{Package \xpackage{pdfcol}}
+%
+% \begin{macrocode}
+\RequirePackage{pdfcol}[2007/09/09]
+\ifpdfcolAvailable
+\else
+ \PackageInfo{pdfcolparcolumns}{%
+ Loading aborted, because color stacks are not available%
+ }%
+ \expandafter\endinput
+\fi
+% \end{macrocode}
+%
+% \subsubsection{Package \xpackage{infwarerr}}
+%
+% \begin{macrocode}
+\RequirePackage{infwarerr}[2007/09/09]
+% \end{macrocode}
+%
+% \subsection{Color stack macros}
+%
+% \begin{macro}{\pcpc@MaxStack}
+% Macro \cs{pcpc@MaxStack} holds the highest number of
+% allocated stacks.
+% \begin{macrocode}
+\global\chardef\pcpc@MaxStack=\z@
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\pcpc@InitStacks}
+% Macro \cs{pcpc@InitStacks} takes the number of columns
+% as argument and ensures that there are enough color
+% stacks for all columns.
+% \begin{macrocode}
+\def\pcpc@InitStacks#1{%
+ \ifnum#1>\pcpc@MaxStack
+ \begingroup
+ \count@\pcpc@MaxStack
+ \loop
+ \advance\count@\@ne
+ \pdfcolInitStack{pcpc@\the\count@}%
+ \ifnum#1>\count@
+ \repeat
+ \global\chardef\pcpc@MaxStack=\count@
+ \endgroup
+ \fi
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\pcpc@SwitchStack}
+% \begin{macrocode}
+\def\pcpc@SwitchStack#1{%
+ \pdfcolSwitchStack{pcpc@\number#1}%
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\pcpc@SetCurrent}
+% \begin{macrocode}
+\def\pcpc@SetCurrent#1{%
+ \pdfcolSetCurrent{pcpc@\number#1}%
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Patches}
+%
+% Now the color stack macros are patched into the macros
+% of package \xpackage{parcolumns}.
+%
+% \subsubsection{Init stacks}
+%
+% \cs{pcpc@InitStacks} should go into the definition of
+% environment |parcolumns|. \cs{pc@alloccolumns} is executed
+% there and nowhere else, thus we hook into it.
+% \begin{macrocode}
+\g@addto@macro\pc@alloccolumns{%
+ \pcpc@InitStacks\pc@columncount
+}
+% \end{macrocode}
+%
+% \subsubsection{Switch stack}
+%
+% \cs{pcpc@SwitchStack} should be called by marco \cs{colchunk@}.
+% However it is easier to patch \cs{pc@setcolumnwidth} that
+% is executed in \cs{colchunk@} only.
+% \begin{macrocode}
+\g@addto@macro\pc@setcolumnwidth{%
+ \pcpc@SwitchStack\pc@columnctr
+}
+% \end{macrocode}
+%
+% \subsubsection{Set current stack color}
+%
+% \cs{pcpc@SetCurrent} is set at the begin of each line.
+% It must be inserted into \cs{pc@placeboxes}. Unhappily
+% there is no easy way. Therefore we check and
+% redefine \cs{pc@placeboxes}.

+% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\url{http://ctan.org/pkg/pdfcolparcolumns}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/oberdiek/pdfcolparcolumns.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/oberdiek/pdfcolparcolumns.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 pdfcolparcolumns.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}
+% \def\t{^^A
+% \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 pdfcolparcolumns.pdf unpack_files output .|

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