% \begin{abstract}
% Color support for dvips in \xfile{dvips.def} involves the
% color stack of dvips. The package tries to remove unnecessary
% uses of the stack to avoid the error ``out of coor stack space''.
% \end{abstract}
%

%
% \section{Documentation}
%
% \subsection{Introduction}
%
% This package tries a solution, if the program
% dvips complains:
% \begin{quote}
% |! out of color stack space|
% \end{quote}
% The driver file \xfile{dvips.def} contains the
% low level color commands for the package \xpackage{color}.
% Each time a color is set, the current color is
% pushed on the color stack before and after the
% current group the old color is popped from
% the stack and set again (via \cs{aftergroup}).
% But the color stack size of dvips is limited,
% so a stack overflow can occur, if there are
% too many color setting operations in a group.
%
% Only at the bottom group level (no group),
% the color can be set directly without pushing
% the current color on the stack before, because
% there is no group at bottom level that can end.
%
% With \eTeX\ the group level can easily be
% detected (\cs{currentgrouplevel}).  Alone with
% \TeX\ this is not possible.
%
% \subsection{Usage}
%
% \subsubsection{With \eTeX}
%
% With e-TeX the package fixes \cs{set@color}, therefore
% no interaction with the user is required. Just load the package:
% \begin{quote}
% |\usepackage[dvips]{color}|\\
% |\usepackage{dvipscol}|
% \end{quote}
%
% \subsubsection{Without \eTeX}
%
% \begin{quote}
% |\usepackage[dvips]{color}|\\
% |\usepackage{dvipscol}|
% \end{quote}
% Without \eTeX\ the package does not know, which \cs{color}
% do not need the stack. Therefore it defines \cs{nogroupcolor},
% that the user can use manually instead of \cs{color}.
% But caution: it should only be used outside of all
% groups, for example the following will not work:
% \begin{quote}
%   |\textcolor{black}{\nogroupcolor{blue}...}|
% \end{quote}
%
% The use of \eTeX is strongly recommended.

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