I've learned that SMMP[1] is public domain and well documented[2].  It
consists of a single fortran file with no external dependencies.  I
successfully ran f2py on smmp.f and was able to load the module into
python.

Is there any reason that SMMP could/should not be used for sparse
matrix multiplies?  If not I can try making the necessary changes.
