Hi Gustavo, thanks for looking at this, and James too.

I've added a test now, and refactored the definition of has_zope and
its companions into the tests.zope package rather than in
tests.zope.zstorm.

If this isn't really what you're looking for, let's have a chat on IRC
before I head off into the wild again.
