As a warning, when something's labeled as "deprecated" in Python, the
implementors really mean it: 'rotor' is gone in the upcoming Python 2.4
release.

So, unless there's an overriding reason, don't ignore DeprecationWarnings,
because there is a strong chance that code that uses a deprecated feature
won't work in the future.  Warnings are there for a reason!  *grin*
