-power interface because
some highlevel code of PolyBoRi is written in Python. If we can _replicate_
what is done using Boost with Cython -- I know we can, the question is how
long it takes -- the highlevel-code would still work. So in this scenario
we'll have to wrap twice.
I strongly fa

you wonder: not integrating PolyBori is not an option for me :-)
Any ideas? Thoughts?

This might be a bit off topic, but someone wrote a nice review of SAGE at

me core SAGE objects might be implemented in Python and call a
Pyrex class handling NTL for them. Also libs/ntl could still exist as an NTL
