Brief recipe:

Start with xxmodule.c (in the Modules directory in the source 
distribution).  Modify as needed to define your module's functions 
and data types (refer to the embedding/extending docs).

Build a CodeWarrior shared library project that includes xxmodule.c 
and the PythonCore shared library from your system folder.  Name the 
output shared library "xx.ppc.slb".  Put it somewhere in the module 
search path.

In xxmodule.c, export the function "initxx" (where xx is the module 
name).  This is most simply done by bracketing it with #pragma export.

#pragma export on
extern "C" void		// I'm using C++ so extern "C" is neede
initxx()
{
	...
}
#pragma export off

Hope I didn't forget anything :)
