+ *
+ * The Mesa Main module consists of all the files in the main/ directory.
+ * Among the features of this module are:
+ * <UL>
+ * <LI> Structures to represent most GL state </LI>
+ * <LI> State set/get functions </LI>
+ * <LI> Display lists </LI>
+ * <LI> Texture unit, object and image handling </LI>
+ * <LI> Matrix and attribute stacks </LI>
+ * </UL>
+ *
+ * Other modules are responsible for API dispatch, vertex transformation,
+ * point/line/triangle setup, rasterization, vertex array caching,
+ * vertex/fragment programs/shaders, etc.
+ *
+ *
+ * \section AboutDoxygen About Doxygen
+ *
+ * If you're viewing this information as Doxygen-generated HTML you'll
+ * see the documentation index at the top of this page.
+ *
+ * The first line lists the Mesa source code modules.
+ * The second line lists the indexes available for viewing the documentation
+ * for each module.
