This package is based on the package 'python-zopeinterface' from project 'openSUSE:11.3'.

Interfaces are objects that specify (document) the external behavior of
objects that "provide" them. An interface specifies behavior through:

- informal documentation in a doc string

- attribute definitions

- invariants, which are conditions that must hold for objects that
provide the interface

This is a separate distribution of the zope.interface package used in
Zope 3.
