+ * This file is a template which generates the OpenGL API entry point
+ * functions.  It should be included by a .c file which first defines
+ * the following macros:
+ *   KEYWORD1 - usually nothing, but might be __declspec(dllexport) on Win32
+ *   KEYWORD2 - usually nothing, but might be __stdcall on Win32
+ *   NAME(n)  - builds the final function name (usually add "gl" prefix)
+ *   DISPATCH(func, args, msg) - code to do dispatch of named function.
+ *                               msg is a printf-style debug message.
+ *   RETURN_DISPATCH(func, args, msg) - code to do dispatch with a return value
+ *
+ * Here is an example which generates the usual OpenGL functions:
+ *   #define KEYWORD1
+ *   #define KEYWORD2
+ *   #define NAME(func)  gl##func
