combining large C-programme with Python

[Pieter De Ceuninck]

Hello,

I'd like to know if anyone can give some projects where existing C-code
was modularized using Python. I'm planning to redesign (refactor) a
large C-code with a new top-layer of Python and the necessary
adaptations (as few as possible) in the underlying (numerical,
scientific computing) C-code. I'm not talking about writing _new_
scientific computing python-code with numpy or so, just using existing
C-code.
If no such projects are known, what would be a good way to refactor that
huge code ? Complete re-implementation is not an option :-)

thx,
Pieter
