Easier said than done. I spent almost all of a Sage Days in Seattle in March 2011 and almost all of another in December 2011 working on this. At the time, simon's scripts were unreadable by gp2c but that changed.

And its author (Mike Ribinstein) was here in Warwick a week ago, but does not himself use Sage. The interface was done by a student of his who is no longer around (Rishikesh, please correct me if I am wrong and you are reading this!)
