#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 :]
