[Python-checkins] CVS: python/dist/src/Mac/Modules/cf CFmodule.c,NONE,1.1

[Jack Jansen]

Update of /cvsroot/python/python/dist/src/Mac/Modules/cf
In directory usw-pr-cvs1:/tmp/cvs-serv24696/Python/Mac/Modules/cf

Added Files:
	CFmodule.c 
Log Message:
First small step towards bgen-generated CoreFoundation. there is hardly any real functionality yet, but method chains seem to work, and so do Retain/Release semantics.

--- NEW FILE: CFmodule.c ---
