I reviewed zope.component 4.3.0-1 as checked into eoan. This shouldn't be
considered a full audit but rather a quick gauge of maintainability.

Zope is a free and open source web application server written in the
object-oriented programming language “Python”.
zope.component is a framework that provides facilities for defining,
registering and looking up components.

The project didn't receive a commit for the past 8 months but it is still
maintained and the code is mature.
