Are you sure?

Does the pep really allow for:

from mortar import content
from mortar.rdb import something

...where 'content' is a function defined in mortar/__init__.py and 
'something' is a function defined in mortar/rdb/__init__.py *and* the 
following are separate distributions on PyPI:

- mortar
- mortar.rdb

...where 'mortar' does not contain 'mortar.rdb'.

No, they have nothing but a (functionally) empty __init__.py in the zope 
package.

cheers,

Chris
