% \maketitle
%
% \begin{abstract}
% This packages fixes bugs in \xpackage{parallel} and
% improves color support by using several color stacks
% that are provided by \pdfTeX\ since version 1.40.
% \end{abstract}
%
% \tableofcontents
%
% \section{Usage}
%
% \begin{quote}
% |\usepackage{pdfcolparallel}|
% \end{quote}
% The package \xpackage{pdfcolparallel} loads package \xpackage{parallel}
% \cite{parallel} and redefines some macros to fix bugs.
%
% If color stacks are available then package \xpackage{parallel}
% is further patched to support them.
%
% \subsection{Option \xoption{rulebetweencolor}}
%
% Package \xpackage{pdfcolparallel} also fixes the color for the
% rule between columns.
% Default color is \cs{normalcolor}. But this can be changed by using
% option \xoption{rulebetweencolor} for |\setkeys{parallel}|
% (see package \xpackage{keyval}). The option takes a color specification
% as value. If the value is empty, then the default (\cs{normalcolor})
% is used.
% Examples:
% \begin{quote}
%   |\setkeys{parallel}{rulebetweencolor=blue}|,\\
%   |\setkeys{parallel}{rulebetweencolor={red}}|,\\
%   |\setkeys{parallel}{rulebetweencolor={}}|,
%     \textit{\% \cs{normalcolor} is used}\\
%   |\setkeys{parallel}{rulebetweencolor=[rgb]{1,0,.5}}|
% \end{quote}
%
% \subsection{Future}
%
% If there will be a new version of package \xpackage{parallel}
% that adds support for color stacks, then this package may become
% obsolete.

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