-<h2>Object Graphics Library</h2>
-
-The Object Graphics Library is a library supporting the creation and
-manipulation of simple and complex graphic images on a canvas.
-
-<p>The OGL library was originally written in C++ and provided to
-wxPython via an extension module wrapper as is most of the rest of
-wxPython. The code has now been ported to Python (with many thanks to
-Pierre Hjälm!) in order to make it be more easily maintainable and
-less likely to get rusty because nobody cares about the C++ lib any
-more.
