[Zope-dev] Don't have "Zope 2" hard-specify its versions!

Indeed, so we'd need 2 eggs for Zope 2 :-(

Something I bumped into recently:

If the Zope 2 egg actually hard-specifies its dependencies, how do I 
upgrade any of those dependencies to newer versions that fix bugs i may 
have encountered/fixed?

With buildout-only, it's easy, just override the versions in the 
versions section of the topmost buildout.cfg.

How would this be done if the Zope 2 egg or meta-egg hard-specifies the 
versions?
