Many thanks are owed to Jean-Sebastien for his assistance in this 
area.   I would like to echo, however, Pearu's suggestion that there is 
no need to convert working Fortran code to C for inclusion into scipy.   
f2py actually makes the process of integrating fortran code into SciPy 
easier than integrating C code.

So, unless there is an important reason to convert to C (dynamic memory 
allocation for example), I would think it is better to keep Fortran code 
in Fortran when possible.

Thanks again,  Jean,

-Travis
