-\begin{document}
-\maketitle
-
-The \code+ocgx+ package extends and documents the \code+ocg+ package
-(which comes with Asymptote) which allows you to create OCGs
-(\emph{Optional Content Group}) in PDF documents.
-
-Every OCG includes \TeX{} material into a layer of the PDF file. Each of
-these layers can be displayed or not. Links can enable or disable the
-display of OCGs.
-
-The \code+ocgx+ package does not use Javascript embedded in the PDF
-document to enable or disable OCGs. Thus, it is usable with several PDF
-readers (to date, it has been successfully tested with \emph{Acrobat
-  Reader}, \emph{Foxit Reader}, and \emph{Evince}).
-
-\section{Usage}
-
-Here is a simple example.
-
-\TeXexample{ocgx-example-1.tex}{}
-
-This document creates an OCG called \emph{ocg1} containing the text
-``\emph{first example.}''  which is visible. You can show or hide this
-OCG by clicking the link ``\emph{Button.}''.
-
-\subsection{Create OCGs}
-
-\begin{note}
-  The \code+ocg+ package written by Michael \textsc{Ritzert} comes
-  without documentation. In my knowledge, the only documentation for
-  this package is offered (by Kjell Magne Fauske) on the weblog of
-  TeXample.net:
-  \url{http://www.texample.net/weblog/2008/nov/02/creating-pdf-layers/}.

-\DescribeEnv{ocg}%
-The \code+ocg+ environment (provided by the package \code+ocg+) creates
-OCGs. It requires three arguments. The first argument is the name of the
-OCG as it appears in the PDF viewer. The second argument is the internal
-name used to reference this OCG. The third argument is a flag that
-indicates whether the OCG should be visible or not (1 for visible, 0 for
-invisible). The content of the environment (any \TeX material) is added
-into the OCG.
-
-The following code creates an OCG named \emph{OCG name} with
-\emph{refocg} as internal reference. The content of this OCG is
-``\emph{content...}''. This OCG is visible (the third argument is 1).
-
-\begin{lstlisting}[style=TeXcode]
-  \begin{ocg}{OCG name}{refocg}{1}
-    content...
-  \end{ocg}
-\end{lstlisting}
-
-\begin{note}
-  The same reference can be used with several \code+ocg+ environments (not
-  necessarily in the same page). All materials are grouped in the same
-  OCG. Only the first name provided will be used.
-\end{note}
-
-\begin{note}
-  A reference of an OCG consists of letters (A-Z, a-z), numbers (0-9)
-  and possibly the \code+@+ character.
-\end{note}
-
-\begin{note}
-  The content of the \code+ocg+ environment should not span across
-  multiple pages. Currently, nothing prevents you to try it but the
-  result will certainly not be the one you were expecting!
-\end{note}
-
-\begin{note}
-  It is possible to nest an OCG in another OCG. To display the internal
-  OCG, both the internal and external OCGs need to be in the visible
-  state.
-\end{note}
-
-\subsection{Manage the visibility of OCGs}
-
-\DescribeMacro{\switchocg}%
-The \code+\switchocg+ macro turns its second argument into a clickable
-link that toggles the visibility status of all listed OCGs (by their
-reference) in its first argument: if an OCG was visible, it becomes
-invisible, and conversely, if an OCG was invisible, it becomes visible.
-
-The following code creates the link \emph{toggle} that switches the
-visibility status of OCGs whose references are \emph{ocg1} and
-\emph{ocg2}:
-
-\begin{lstlisting}[style=TeXcode]
-  \switchocg{ocg1 ocg2}{toggle}
-\end{lstlisting}
-
-\DescribeMacro{\showocg}%
-The \code+\showocg+ macro turns its second argument into a clickable
-link that make visible all OCGs whose references are listed in its first
-argument: an invisible OCG becomes visible and an OCG already visible
-remains visible.
-
-The following code creates the link \emph{show} which makes visible the
-OCGs whoses references are \emph{ocg1} and \emph{ocg2}:
-
-\begin{lstlisting}[style=TeXcode]
-  \showocg{ocg1 ocg2}{show}
-\end{lstlisting}
-
-\DescribeMacro{\hideocg}%
-The \code+\hideocg+ macro turns its second argument into a clickable
-link that make invisible all OCGs whose references are listed in its
-first argument: a visible OCG becomes invisible and an OCG already
-invisible remains invisible.
-
-The following code creates the link \emph{hide} which makes invisible
-the OCGs whoses references are \emph{ocg1} and \emph{ocg2}:
-\begin{lstlisting}[style=TeXcode]
-  \hideocg{ocg1 ocg2}{hide}
-\end{lstlisting}
-
-\DescribeMacro{\actionsocg}%
-The \code+\actionsocg+ macro transforms its fourth argument in a
-clickable link. Its three first arguments are lists of references of
-OCGs. The first list contains references of OCGs which visibility status
-is to be toggled. The second list contains references of OCGs to be set
-visible. The third list contains references of OCGs to be set invisible.
-
-The following code creates the link \emph{actions} to toggle the
-visibility status of the OCG named \emph{ocg1}, to make visible the OCG
-named \emph{ocg3}, and to make invisible OCG named \emph{ocg2}:
-
-\begin{lstlisting}[style=TeXcode]
-  \actionsocg{ocg1}{ocg3}{ocg2}{actions}
-\end{lstlisting}
-
-\subsection{Usage with \TikZ{}}
-
-You can use the \code+ocgx+ package with \TikZ{}. The package provides a
-\TikZ{} library offering five specific styles to transform a path
-(\code+\path+ or \code+\node+) in a clickable link. To use it, simply
-add the following lines in your preamble:
-
-\begin{lstlisting}[style=TeXcode]
-  \usepackage{tikz}
-  \usetikzlibrary{ocgx}
-\end{lstlisting}
-
-\begin{list}{}
-\item
-\noindent\style+/tikz/switch ocg+\argument{=\{\emph{<OCGs list>}\}}
-
-This style transforms the path or the current node in a link acting as
-if it was produced by the macro \code+\switchocg+ (the visibility status
-of referenced OCGs is reversed).
-
-\noindent\style+/tikz/show ocg+\argument{=\{\emph{<OCGs list>}\}}
-
-This style transforms the path or the current node in a link acting as
-if it was produced by the macro \code+\showocg+ (the referenced OCGs are
-made visible).
-
-\noindent\style+/tikz/hide ocg+\argument{=\{\emph{<OCGs list>}\}}
-
-This style transforms the path or the current node in a link acting as
-if it was produced by the macro \code+\hideocg+ (the referenced OCGs are
-made invisible).
-
-\noindent\style+/tikz/actions ocg+\argument{=\{\emph{<OCGs
-    list>}\}\{\emph{<OCGs list>}\}\{\emph{<OCGs list>}\}}
-
-This style transforms the path or the current node in a link acting as
-if it is produced by the macro \code+\actionsocg+ (the visibility status
-of OCGs of the first list is reversed, the OCGs in the second list are
-made visible and those of the third list are made invisible).
-
-\noindent\style+/tikz/switch ocg with mark on+\argument{=\{\emph{<ocg reference>}\}\{\emph{<OCGs list>}\}}
-
-\noindent\style+/tikz/switch ocg with mark off+\argument{=\{\emph{<ocg reference>>}\}\{\emph{<OCGs list>}\}}
-
-These styles transform the path or the current node in a link acting as
-if it is produced by the macro \code+\switchocg+ (the visibility status
-of referenced OCGs in the list is reversed).
-
-A mark (currently a simple cross) is drawn over the current path or node
-in an OCG whose reference is \texttt{\emph{ocg reference}}. The
-visibility status of this OCG will be reversed as those of the entire
-list.
-
-If the OCG whose reference is \texttt{\emph{ocg reference}} does not
-exist, it is created with an empty name and its initial visibility state
-is true with \code+on+ and false with \code+off+.
-\end{list}
-
-\begin{note}
-  Whatever the shape of the current path or node is, it is its
-  \emph{bounding box} that is used to make the link (the link is always
-  \emph{rectangular} and \emph{horizontal}).
-\end{note}
-
-\section{Examples}
-
-The document \code+demo-ocgx.tex+ provides several examples of usage of
-package \code+ocgx+ with \TikZ{} (and \code+beamer+).
-
-\section{Limits and bugs}
-
-\begin{enumerate}
-\item Links are always horizontal rectangles!
-\item An \code+ocg+ environment spanning across multiple pages are not
-  detected and don't work correctly.
-\item The list of OCGs created by \code+ocg+ is seen by viewers as a
-  long flat list. Their possible hierarchy is not displayed.
-\item The packages \code+ocg+ and \code+ocgx+ are not compatible with Plain-\TeX{}.
-\end{enumerate}
-
-\section{Development}
-This package is still experimental. It is released on CTAN. You can
-recover the latest version on \url{https://github.com/polgab/ocgx}. Any
-help to participate in its development is welcome: contact the
-maintainer (\url{paul.gaborit@gmail.com}).
