+%
+% \begin{abstract}
+% Package \xpackage{luacolor} implements color support based
+% on \LuaTeX's node attributes.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% \subsection{Introduction}
+%
+% This package uses a \LuaTeX's attribute register to
+% to annotate nodes with color information.
+% If a color is set, then the attribute register
+% is set to this color and all nodes created in its scope
+% (current group) are annotated with this attribute.
+% Now the color property behaves much the same way
+% as the font property.
+%
+% \subsection{Usage}
+%
+% Package \xpackage{color} is loaded automatically by this
+% package \xpackage{luacolor}. If you need a special driver
+% option or you prefer package \xpackage{xcolor}, then load
+% it before package \xpackage{luacolor}, for example:
+% \begin{quote}
+%   |\usepackage[dvipdfmx]{xcolor}|
+% \end{quote}
+% The package \xpackage{luacolor} is loaded without options:
+% \begin{quote}
+%   |\usepackage{luacolor}|
+% \end{quote}
+% It is able to detect PDF mode and DVI drivers are
+% differentiated by its color specials. Therefore the
+% package do need driver options.
+%
+% Then it redefines the color setting commands to set
+% attributes instead of whatsits for color.
+%
+% At last the attribute annotations of the nodes in the
+% output box must be analyzed to insert the necessary color whatsits.
+% Currently \LuaTeX\ lacks an appropriate callback function.
+% Therefore package \xpackage{atbegshi} is used to get control
+% before a box is shipped out.
+%
+% \begin{declcs}{luacolorProcessBox} \M{box}
+% \end{declcs}
+% Macro \cs{luacolorProcessBox} processes the box \meta{box}
+% in the previously described manner. It is automatically
+% called for pages, but not for XForm objects.
+% Before passing a box to \cs{pdfxform}, call \cs{luacolorProcessBox}
+% first.
+%
+% \subsection{Limitations}
+%
+% \begin{description}
+% \item[Ligatures with different colored components:]
+%   Package \xpackage{luacolor} sees the ligature after
+%   the paragraph building and page breaking, when a
+%   page is to be shipped out. Therefore it cannot
+%   break ligatures, because the components might occupy
+%   different space. Therefore it is the respondibility
+%   of the ligature forming process to deal with different
+%   colored glyphs that form a ligature. The user can avoid
+%   the problem entirely by explicitly breaking the ligature
+%   at the places where the color changes.
+%  \item \dots

+% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{luacolor}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/luacolor/luacolor.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/luacolor/luacolor.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `luacolor'
+% 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/luacolor.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{luacolor.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+%   |unzip luacolor.tds.zip -d ~/texmf|
+% \end{quote}
+%
+% \paragraph{Script installation.}
+% Check the directory \xfile{TDS:scripts/luacolor/} for
+% scripts that need further installation steps.
+%
+% \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 luacolor.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{luacolor.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 luacolor.dtx
+%makeindex -s gind.ist luacolor.idx
+%pdflatex luacolor.dtx
+%makeindex -s gind.ist luacolor.idx
+%pdflatex luacolor.dtx
+%\end{verbatim}
+% \end{quote}
+%

+%   \begin{Version}{2007/12/12 v1.0}
+%   \item

+%     \cs{pdfliteral} and \cs{special} nodes that might contain
+%     typesetting material.
+%   \item
+%     Bug fix by Manuel P\'egouri\'e-Gonnard: Now colors are also
