We don't have a "Suggest:" tag, unfortunately. It's been suggested
several times but the consensus (of the RPM developers, anyway) seems to
be against it.

Aha. The documentation still lists a dependency on sqlite2 -- I just
noticed now that it's indeed sqlite3 only. This will simplify things.

Eek. So a modular packaging would have storm-zope-core and
storm-zope-complete, and the latter being a virtual package that depends
on whichever zope package contains zope.security and zope.component.

We have python-zope-interface and python-transaction . Will have to
track down where zope.security and zope.component is.

Our Django packaging is currently monolithic, so Django comes with all
the backends. but this strikes me as something that should be done by
the user -- I'll make a note in a README.Fedora file.
