#ifndef _PYGAME_H
#define _PYGAME_H
/** This header file includes all the definitions for the
** base pygame extensions. This header only requires
** SDL and Python includes. The reason for functions
** prototyped with #define's is to allow for maximum
** python portability. It also uses python as the
** runtime linker, which allows for late binding. For more
** information on this style of development, read the Python
** docs on this subject.
** http://www.python.org/doc/current/ext/using-cobjects.html
**
** If using this to build your own derived extensions,
** you'll see that the functions available here are mainly
** used to help convert between python objects and SDL objects.
** Since this library doesn't add a lot of functionality to
** the SDL libarary, it doesn't need to offer a lot either.
**
** When initializing your extension module, you must manually
** import the modules you want to use. (this is the part about
** using python as the runtime linker). Each module has its
** own import_xxx() routine. You need to perform this import
** after you have initialized your own module, and before
** you call any routines from that module. Since every module
** in pygame does this, there are plenty of examples.
**
** The base module does include some useful conversion routines
** that you are free to use in your own extension.
**
** When making changes, it is very important to keep the
** FIRSTSLOT and NUMSLOT constants up to date for each
** section. Also be sure not to overlap any of the slots.
** When you do make a mistake with this, it will result
** is a dereferenced NULL pointer that is easier to diagnose
** than it could be :]
