This package is intended to be independently reusable in any Python
project. It is maintained by the `Zope Toolkit project
<https://zopetoolkit.readthedocs.io/>`_.

This package provides an implementation of "object interfaces" for Python.
Interfaces are a mechanism for labeling objects as conforming to a given
API or contract. So, this package can be considered as implementation of
the `Design By Contract`_ methodology support in Python.

.. _Design By Contract: http://en.wikipedia.org/wiki/Design_by_contract
