+ * This file is a template which generates the OpenGL API entry point

+ * 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
