As an aside, I've often wanted to wrap the gretl library code in Python

much of the numerical python stack is BSD-compatible and this makes me wary
to introduce a GPL library. (No license flame war comments intended.)

Interesting. Thanks. Cython had made great strides since this was written and might make a nice addendum to this note. f2py is more or less abandonware now to be superseded (eventually) by fwrap, though it does work well for what it does. If I can find some spare cycles, I'd like to play around with this idea.
