Factorization

Hi everyone, can you tell me what's the current situation regarding polynomial factorization in GiNaC? According to your wishlist, it's still missing, but I've just read some mails in this list saying that some people are working on the task. I'm a student of mathematics, and my diploma thesis is about polynomial factorization. I'm interested in both factorization in Z[x] and algebraic extensions, and I wonder if I could implement some algorithms or contribute to any ongoing projects. Wolfgang By the way, I've found out how to declare a polynomial ring over modular integers in CLN, so I don't need an example any more.
