Well, zope.app.publication and zope.app.publisher are really completely 
different, despite their similar names.  zope.app.publication is a 
publisher implementation, while zope.app.publisher contains publishable 
resources.  IMHO, zope.app.publisher is more broadly useful than 
zope.app.publication.

So I'm working on removing the dependency from zope.app.publisher to 
zope.app.publication.  It's mostly done, but I'm writing tests for the 
code I'm moving, since it never had any tests...

I'm thinking about also removing the reverse dependency 
(zope.app.publication -> zope.app.publisher).  I think the default view 
name logic might belong in publication, not publisher.
