Subject: Code for overlapping STOs

IS there a free and non obscure piece of code (preferably C) for 
calculating the overlap integrals between two Slater-Type-Orbitals (single 
zeta, radial part, angular parts are real spherical harmonics for s,p, and 
d)?  I have the MOPAC FORTRAN routines, but they are not clear to me.

Thanks in advance.
