+% \begin{abstract}
+% The PDF format has some graphics parameter like
+% line width or text rendering mode. This package
+% provides an interface for setting these parameters.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% This package \xpackage{pdfrender} defines an interface for
+% PDF specific parameters that affects the rendering of
+% graphics or text. The interface and its implementation
+% uses the same technique as package \xpackage{color}
+% for color settings. Therefore this package is loaded to
+% enable \LaTeX's color interface.
+%
+% At different places \LaTeX\ uses \cs{normalcolor} to avoid that
+% header, footer or floats are print in the current color of the
+% main text. \cs{setgroup@color} is used to start a save box
+% with the color that is set at box saving time.
+% Package \xpackage{pdfrender} extends these macros to
+% add its own hooks of its parameters. Therefore \LaTeX3 should
+% generalize \LaTeXe's color interface.
+%
+% \subsection{Usage}
+%
+% In \LaTeX\ the package is loaded as normal package. Options
+% are not defined for this package.
+% \begin{quote}
+% |\usepackage{pdfrender}|
+% \end{quote}
+%
+% This package can also be used in \plainTeX\ and even ini\TeX:
+% \begin{quote}
+% |input pdfrender.sty|
+% \end{quote}
+%
+% \subsection{Macros}
+%
+% \begin{declcs}{pdfrender} \M{key value list}
+% \end{declcs}
+% The first parameter \meta{key value list} contains a
+% list of parameter settings. The key entry is the parameter name.
+% The macro works like
+% \cs{color} (without optional argument) for color setting.
+%
+% \begin{declcs}{textpdfrender} \M{key value list} \M{text}
+% \end{declcs}
+% In the same way as \cs{pdfrender} the first argument
+% specifies the parameters that should be set. This parameter
+% setting affects \meta{text} only. Basically it works
+% the same way as \cs{textcolor} (without optional argument).
+%
+% \subsection{Parameters}
+%
+% The following table shows an overview for the supported
+% parameters and values:
+%
+% \begin{longtable}{@{}l|l|l@{}}

+%
+% \subsubsection{Details}
+%
+% The description and specification of these parameters
+% are available in the PDF specification \cite{pdf-spec}.
+% Therefore they are not repeated here.
+%
+% \begin{description}
+% \item[Value:]
+% The values in the second column lists or describe
+% the values that are specified by the PDF specification.
+% \item[Alias:] Instead of magic numbers the package also
+% defines some aliases that can be given as value.
+% Example: |LineCapStyle=Round| has the same effect as
+% |LineCapStyle=1|.
+% \item[Number:] The term \emph{number} means an integer
+% or real number. The real number is given as plain
+% decimal number without exponent. The decimal separator is a period.
+% At least one digit must be present.
+% \item[\xoption{LineWidth}:] As alias a \TeX\ dimen specification
+% can be given. This includes explicit specifications with number
+% and unit, e.g. |LineWidth=0.5pt|. Also \LaTeX\ length registers
+% may be used. If \eTeX's \cs{dimexpr} is available, then it is
+% automatically added. However package \xpackage{calc} is not
+% supported.
+% \item[\xoption{FillColor}, \xoption{StrokeColor}:]
+% Package \xpackage{color} or \xpackage{xcolor} must be loaded
+% before these options can be used (since version 1.2).
+% \LaTeX's color support sets both colors at the same time
+% to the same value. However parameter \xoption{TextRenderingMode}
+% offers the value \texttt{FillStroke} that makes only sense, if
+% the two color types can be set separately.
+% If one of the options \xoption{FillColor} or \xoption{StrokeColor}
+% is specified, then also the color is set. For compatibility
+% with the \LaTeX\ color packages (\xpackage{color} or \xpackage{xcolor}),
+% always both colors must be set. Thus if one of them is not specified,
+% it is taken from the current color.
+%
+% Both options \xoption{FillColor} and \xoption{StrokeColor}
+% expect a \LaTeX\ color specification as value.
+% Also the optional color model argument is supported.
+% Example:
+% \begin{quote}
+% |FillColor=yellow|,\\
+% |StrokeColor=[cmyk]{1,.5,0,0}|\\
+% \end{quote}
+% \end{description}
+%
+% \subsection{Color stack}
+%
+% If the \pdfTeX\ version provides color stacks, then each
+% parameter is assigned a page based color stack. The assignment
+% of a stack takes place, when its parameter is set the first time.
+% This avoids the use of color stacks that are not needed.

+%
+% \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}

+%
+% \paragraph{TDS.} Now the different files must be moved into
+% the different directories in your installation TDS tree
+% (also known as \xfile{texmf} tree):

+% \subsection{Refresh file name databases}
+%
+% If your \TeX~distribution

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