+% \begin{abstract}
+% The \Lpack{pdfflip} package extends pdf\LaTeX\ making it possible
+% to typeset a ``mirrored'' version of the document. This is
+% sometimes required by publishers who want ``camera-ready''
+% documents to be printable on transparent films, so that one reads
+% the pages correctly by looking \emph{through} the film (i.e., with
+% the \emph{unprinted} side of the film towards his eyes. This
+% package requires \Lpack{everypage} by the same author and works
+% with pdf\LaTeX\ only.

+%
+% \section{Introduction}
+%
+% This \LaTeX\ package makes it possible to typeset a document
+% horizontally flipping its pages. This is sometimes required by
+% publishers who want ``camera-ready'' documents to be printable on
+% transparent films, so that one reads the pages correctly by looking
+% \emph{through} the film (i.e., with the \emph{unprinted} side of the
+% film towards his eyes.
+%
+% It is also possible to activate the mirroring capability on a page
+% by page basis.
+%
+% This package requires \Lpack{everypage} by the same author and works
+% with pdf\LaTeX\ only.
+%
+% \section{User interface}
+% By default, once loaded as:
+% \begin{quote}
+% |\usepackage{pdfflip}|
+% \end{quote}
+% the \Lpack{pdfflip} becomes immediately \emph{active} (i.e., starts
+% flipping horizontally every page). Conversely, by selecting the
+% \Lopt{off} option as in
+% \begin{quote}
+% |\usepackage[off]{pdfflip}|
+% \end{quote}
+% The package is loaded but remains inactive.
+%
+% \DescribeMacro{\FlipPDF}\DescribeMacro{\UnFlipPDF}
+% The |\FlipPDF| command lets one switch on page flipping. Conversely,
+% |\UnFlipPDF| switches off page flipping.
+%
+% \StopEventually {}
+%
+% \section{Implementation}
+%
+% Announce the name and version of the package, which requires
+% \LaTeXe (actually pdfLaTeX).
+% \begin{macrocode}
+\NeedsTeXFormat{LaTeX2e}
+\ProvidesPackage{flippdf}%
+ [2006/06/30 1.0 Horizontal flipping of pages with pdfLaTeX]
+% \end{macrocode}
+%
+% Reminds the dependence on \Lpack{everypage}.
+% \begin{macrocode}
+\RequirePackage{everypage}
+% \end{macrocode}
+% \begin{macro}{\if@sc@flippdf}
+%
+% Defines a boolean variable to remember if pages are to be flipped or
+% not.
+% \begin{macrocode}
+\newif\if@sc@flippdf
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\FlipPDF}\begin{macro}{\UnFlipPDF}
+% Define the commands used to switch on and off the horizontal
+% flipping of the document pages.
+% \begin{macrocode}
+\newcommand\FlipPDF{\@sc@flippdftrue}
+\newcommand\UnFlipPDF{\@sc@flippdffalse}
+% \end{macrocode}
+% \end{macro}\end{macro}
+%
+% By default activate the flipping:
+% \begin{macrocode}
+\FlipPDF
+% \end{macrocode}
+%
+% Set up the processing of options:
+% \begin{macrocode}
+\DeclareOption{off}{\UnFlipPDF}
+\ProcessOptions
+% \end{macrocode}
+%
+% And eventually, tell \LaTeX\ to flip every page, by using the
+% \Lpack{everypage} hook:
+% \begin{macrocode}
+\AddEverypageHook{%
+ \if@sc@flippdf
+ \pdfliteral direct {-1 0 0 1 \strip@pt\paperwidth\space 0 cm}
+ \fi}
+\endinput
+% \end{macrocode}
