Yeah, zope.site isn't completed yet, as currently zope.app.component 
relies on zope.site and vice versa. The vice versa needs to go away and 
that can be done by extracting more from zope.app.component (the 
implemnentation of various ZCML directives) into another package.

Thanks for the explanation. We are using tl.eggdeps and dot as well 
already, though.

This also takes some information about dependencies we'd like to remove 
from the graph, so instead we've created the full messy graph but 
removing nodes that are already have no dependencies, or have clear 
layering (such as zope.interface, zope.component). The remaining graph 
then gives us clues about what we should focus on.
