Look at a combination of the SWIG tool (I can't remember where it's at but it
stands for Simplified Wrapper Interface Generator so you can search for it) and
a C wrapper for you fortran function. Basically, make it so you can call the
fortran from C. Then swig the C function and link the cstuff.o and fstuff.o with
cstuff_wrap.o (from SWIG) into a shared library then you can follow choice 2
from the other response to this post.
