63 eggs these days, by my measurement. Still far too many. I think with 
some effort we can chop off quite a few more.

Look here at the main cycles in that graph (this is the cause of a lot 
being pulled in that shouldn't be):


It looks we need to pull more out of zope.app.component somewhere else 
so zope.app.publisher doesn't need to depend on zope.formlib anymore. 
Probably ZMI stuff holding things in. The other tricky line is the 
dependency of zope.app.publisher on zope.app.publication.

I'm worried that one person's truly reusable is another person's package 
that is really useless without a huge amount of buy-in.
