I meant to include this link in my previous email:
http://swiki.squeakfoundation.org/squeakfoundation/103
but couldn't find it on the swiki because it was on a different swiki!
(I spent a bit of time cleaning up some of the license-related pages
on the minnow swiki, and adding links from minnow to the URL above)
