+% \maketitle
+%
+% \begin{abstract}
+% Package \xpackage{pdflscape} adds PDF support to the
+% environment \texttt{landscape} of package \xpackage{lscape}
+% by setting the PDF page attribute \texttt{/Rotate}.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% \subsection{Supported drivers}
+%
+% \begin{itemize}
+% \item \xoption{pdftex},\xoption{luatex}
+% \item \xoption{dvips}, \xoption{dvipsone},
+%       \xoption{pctex32}, \xoption{pctexps}
+%       (and other drivers that provide a non-empty \cs{Gin@PS@raw})
+% \item \xoption{dvipdfm}
+% \end{itemize}
+%
+% \subsection{Caveat}
+%
+% Depending on the configuration Ghostscript
+% adds a guessed rotation entry by its own.
+% This can lead to two |/Rotate| entries per page.
+% To prevent this behaviour set the parameter
+% |AutoRotatePages| to |/None|, eg:
+% \begin{quote}
+%   |ps2pdf -dAutoRotatePages=/None|
+% \end{quote}
+%
+% \subsection{Requirements}
+%
+% \begin{itemize}
+% \item The package \xpackage{lscape}.
+% \item The package \xpackage{atbegshi} for all drivers
+%        except \xoption{pdftex},\xoption{luatex}.
+% \end{itemize}
+%
+% \subsection{Usage}
+%
+% Load this package instead of or after package \xpackage{lscape}:
+% \begin{quote}
+%   |\usepackage{pdflscape}|\\
+%   |\begin{landscape}|\dots|\end{landscape}|
+% \end{quote}

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