[f2py] example of setup.py

Hi,

Does anyone have an example of a simple setup.py file to build a  
module which includes both python and fortran sources?

It seems that numpy.distutils should be used, not scipy_distutils  
(which doesn't seem to exist anymore), but I can't manage to find a  
simple example. Say I have three files:

mymodule/__init__.py
mymodule/somecode.py
src/fastcalc.f90

What is the simplest setup.py file I can use to build this module?

Thanks!

Thomas
