The Ubuntu packaging keeps all these backends in the main package, and
suggests python-psycopg2, python-mysqldb and python-pysqlite2.  The
idea being that the Storm package will work without them but gain
functionality if they are installed.  I'm not sure how well that works
with RPM packaging though.

If the aim is to only include parts that will work with the required
dependencies, you might be able to include the sqlite backend in the
main package since it should work with the sqlite binding in the
Python standard library.

Note that the minimum requirements of storm.zope are just the
"zope.interface" and "transaction" packages from Zope 3 -- you don't
need the entire set of Zope modules.  It also has optional
dependencies on zope.security and zope.component (they aren't required
when using storm.zope with storm.django).

This point might be moot if Fedora hasn't packaged the modularised
Zope tree yet (it hasn't been fully packaged for Debian/Ubuntu).

If you want to use storm.django with PostgreSQL, you'll need to have
both Storm's and Django's PostgreSQL backends installed.  The same
goes for MySQL.  I'm not sure whether that is easy to represent in
your dependencies or not.

Other than that, you are correct: storm.django depends on Django and
storm.zope, and storm.zope depends on Zope's zope.interface and
transaction packages.

Good idea.  We've been a bit lax about updating documentation.
