Extendin/Embedding architecture diagram

[Marcelo A. Camelo]

Hi!

I remember running into a nice diagram of the layered architecture of
Python embedding/extending that I'd like to use in a presentation. It
was probably on some embedding or extending tutorial, but I can't
remember where. I couldn't find it on google, neither. 

Does anyone on the list knows about it? Or was I dreaming?

Cheers,

Marcelo A. Camelo
