+%
+% \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@{}}
+% \bfseries Parameter & \bfseries Value & \bfseries Alias\\*

+%
+% \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.

+%
+% \paragraph{Package.} This package is available on

+%
+% \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 pdfrender.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{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}
+%

+% \item[Friedrich Vosberg] asked in the
+%   newsgroup \textsf{de.comp.text.tex} for the font
+%   outline feature \cite{news-Vosberg}.
+% \item[Gaius Pupus] proposed the basic method
+%   using \cs{pdfliteral} in this thread \cite{news-Pupus}.
