Ok, sounds reasonable. Now what about the old packages using
a) /usr/lib/zope/lib/python/Products? Should they move to
b) /usr/share/zope/Products ASAP? If so, what's the best way to do it?
I mean one definitely has to purge a) before an update, but is it safe to
just remove those files? What if they were locally modified?
