Good!
# but it appears to do multivariate factorization as well:
yes it does.
Note that doc should be updated accordingly.
# The following seems to take forever:
t; -E20^16*E4^8*E5^8*E1^16*q^4-(E10^24-E20^8*E5^16)*E4^16*E1^8+E2^24*E20^16*E5^8*q^4 factor(t);

Is the latter a huge-ish task or does ginac have a performance issue here?
I ran the example and I get an exception! So, it seems there is a bug somewhere. I'll have a look at it.
Please keep me in the loop. Also it appears sage is using ginac, so they should be notified when this is fixed.
