Duh. :)

Makes sense, I guess, except that it still looks like it actually does 
something up there (while it's really just a variable that you refer to 
from other sections). It also seems to me it leads to cargo-cult 
buildouts, like in Plone, where for no apparent reason, elementree and 
PIL are always in that eggs option.

It shoudl really just be enough to specify five.grok. And maybe 
zope.component to specify the version boundaries explicitly.
