I am not aware of the packages for AXIOM, so others might comment on that,

This is the most advanced summation package I ever saw, and it handles
rather difficult cases. Downside is that it is written for mathematica and
has a about 10^4 lines of code (as Schneider told me). Furthoermore, its
not literate codes and the algorithms are sparcely documented in research
papers only (if at all)....
Donno if that helps...
