P.S. to cutterjohn: I just looked at what they call a symbolic package for Octave. That's not a CAS, it only gives basic symbolic expression, but no factorization, no symbolic integration, etc... That is expected since it is based on ginac which means Ginac Is Not A Cas, while giac means Giac Is A Cas.
