% \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}
% 
% If the PDF management is loaded by the use of \verb+\DocumentMetadata{}+ at
% the beginning of the document, the engines and backends supported by \texttt{l3backend}
% can be used. Driver options are passed to graphics and are typically only needed if
% \LaTeX{} is used with \texttt{dvipdfmx}. 
% 
% Without the PDF management the following driver options can be used (many are
% simply aliases to each other):
%
% \begin{itemize}
% \item \xoption{pdftex},\xoption{luatex}
% \item \xoption{dvips}, \xoption{dvipsone},
%       \xoption{pctexps}
%       (and other drivers that provide a non-empty \cs{Gin@PS@raw})
% \item \xoption{dvipdfm}, \xoption{dvipdfmx}, \xoption{xetex} 
% \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}
%
% \StopEventually{

% as it would use \cs{pdfpageattr} which is incompatible with the pdf management.
%    \begin{macrocode}
\DeclareOption*{\PassOptionsToPackage\CurrentOption{graphics}}
\ProcessOptions
\RequirePackage{lscape}
%    \end{macrocode}
% this always turns in the same direction as the original code 
% of pdflscape does. left and right would need
% \verb+\pdfmanagement_add:nnn{ThisPage}{Rotate}{..}+
% on every page (e.g. in a shipout hook) and some option to control the wanted
% orientation.

%    \begin{macrocode}
\tl_new:N\g__pdflscape_saverotate_tl
\hook_gput_code:nnn {env/landscape/begin}{pdflscape}

% 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}
