If your package depends on zope.app.publisher, you get *78* eggs.  Change that 
install_requires line in your package to "ZTK" and you get the same software. 
OTOH, packages that rely on things that are *truly reusable* like 
zope.interface, and so on will need to do nothing; those packages will continue 
to have a life of their own.
