Import this, that, and the other thing. Custom importers
Presented by Brett Cannon
Since Python 2.3, the ability has existed to customize the import process so that one can support code stored in alternative formats, e.g. zipimport and its support of importing code from a zip file. The aim of this talk is to make sure you understand how the custom import mechanism works and how to write your own custom importers using importlib from Python 3.1.
