Right, I'm trying to do as little as possible to keep Principia moving
forward until the Ensemble repository work is ready. I don't think we
need to meet in the middle.. I fully expect most of what I'm doing now
will be superseded by ensemble's repository work, hopefully soon. :)

Doing anything at all is just a stop gap to make sure people can
try out the formulas now with the PPA, and possibly submit patches
easily. Hopefully it does not live for very long. However, I plan to
encourage people to try out Ensemble at a few conferences in the next
few weeks, so I want to make sure the experience is smooth as they move
from the examples to Principia.
