+==================================
+ The `ocgx2' LaTeX Package
+
+ Version 0.6 [2015/06/18]
+
+ (C) 2015--\today Alexander Grahn
+==================================
+
+
+1. Introduction
+===============
+
+The intent of this package is to be a drop-in replacement for the already
+existing package `ocgx' by Paul Garborit.
+
+It re-implements the functionality of the `ocg', `ocgx' and `ocg-p' packages
+and adds support for all known engines and back-ends including:
+
+  *  LaTeX --> dvips --> ps2pdf/Distiller
+  *  (Xe)LaTeX --> (x)dvipdfmx
+  *  pdfLaTeX, luaLaTeX
+
+To enable dvipdfmx support, pass `dvipdfmx' globally as a class option.
+
+Also, it adds some minor improvements, such as package options,
+remembering option settings of re-opened ocgs, correct behaviour of ocg
+switching links that were themselves placed on layers, compatibility
+with the `animate' and `media9' packages.
+
+`ocgx2' uses code from file `tikzlibraryocgx.code.tex' by P. Garborit to
+enable TikZ styles for creating PDF Layers and clickable layer switching
+links in the `tikzpicture' context.
+
+Just say:
+
+  \usepackage[tikz]{ocgx2}
+
+instead of
+
+  \usepackage{tikz}
+  \usetikzlibrary{ocgx}
+
+to enable these TikZ styles and read the `ocgx' documentation about their usage:
+
+  texdoc ocgx
+
+
+2. Usage
+========
+
+\usepackage[<options>]{ocgx2}
+
+\begin{ocg}[<options>]{<layer name>}{<layer id>}{<initial visibility>}
+  ... material to be put on a PDF layer ...
+\end{ocg}
+
+With <options> : viewocg = always | never | ifvisible
+                 printocg =  always | never | ifvisible
+                 exportocg =  always | never | ifvisible
+                 listintoolbar= always | never | iffirstuse
+
+                 tikz  (package-only option, see above)
+
+Package options have global scope. Environment options override package
+options locally.  `ocg' environments can be nested.
+
+See the `ocg-p' manual about the environment usage and the meaning of
+the available options:
+
+  texdoc ocg-p
+
+Clickable links for switching PDF layer visibility are created with:
+
+  \switchocg{<layer IDs to toggle, space separated>}{<link text>}
+  \showocg{<layer IDs to switch ON, space separated>}{<link text>}
+  \hideocg{<layer IDs to switch OFF, space separated>}{<link text>}
+  \actionsocg{<IDs to toggle>}{<IDs to switch ON>}{<IDs to switch OFF>}{<link text>}
+
+For details about their usage, read the `ocgx' package manual:
+
+  texdoc ocgx
+
+For compatibility with the `ocg-p' package, the following aliases for
+the above commands have been provided:
+
+  \toggleocgs
+  \showocgs
+  \hideocgs
+  \setocgs
