It's probably worth it, but note this means a large jump in the utilized
revision of ptolemy (61797 to 62410) and represents a bit of work:
* build-area-2.3 needs to be deleted and recreated at release (due to movement
of jars) 
* bug#5540 should be fixed.
* Export As=>XML, PNG, etc need to be tested, I've seen work in this area in
ptolemy
* I'll have to remember the black magic used to create a ptolemy 2.3 that
doesn't keep a copy of the ptolemy code on our repository.
(And I think I'm forgetting a few other kepler changes that should/will have to
be included)
