I am on sage-devel, myself. So i wouldn't mind.
But it is of course not *my* code. MeatAxe can be found at
http://www.math.rwth-aachen.de/~MTX/. My contribution is just a wrapper, i
didn't improve the arithmetics. Actually i use a rather old version of
C-MeatAxe. This is because my boss (David Green) wrote C-code for
computing cohomology, relying on the old C-MeatAxe.
Yours
Simon
