Mark Lutz's _Programming Python_ book explains this quite well (I still
use these parts today in fact).  He has two chapters on embedding and
extending Python.

But the documentation on extending Python is pretty well known
deficiency.  Luckily it is far easier than most languages, both to
accomplish and to understand (yet more kudos to Guido).  Actually, in
responce to your earlier posting, I started writing a _SHORT_ webpage
explaining what is needed, which I hope to have available later today.
I plan (and hope) to make it into a How-To later.
