"""Psyco class support module.

'psyco.classes.psyobj' is an alternate Psyco-optimized root for classes.
Any class inheriting from it or using the metaclass '__metaclass__' might
get optimized specifically for Psyco. It is equivalent to call
psyco.bind() on the class object after its creation.

Note that this module has no effect with Python version 2.1 or earlier.

Importing everything from psyco.classes in a module will import the
'__metaclass__' name, so all classes defined after a

       from psyco.classes import *

will automatically use the Psyco-optimized metaclass.
