+"""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.
+
+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.
