This module was adapted from 'protocols.advice', part of the Python
Enterprise Application Kit (PEAK). Please notify the PEAK authors
(pje@telecommunity.com and tsarna@sarna.org) if bugs are found or
Zope-specific changes are required, so that the PEAK version of this module
can be kept in sync.
PEAK is a Python application framework that interoperates with (but does
not require) Zope 3 and Twisted. It provides tools for manipulating UML
models, object-relational persistence, aspect-oriented programming, and more.
Visit the PEAK home page at http://peak.telecommunity.com for more information.

This function is designed to be called by an "advising" function executed
in a class suite. The "advising" function supplies a callback that it
wishes to have executed when the containing class is created. The
callback will be given one argument: the newly created containing class.
The return value of the callback will be used in place of the class, so
the callback should return the input if it does not wish to replace the
class.
The optional 'depth' argument to this function determines the number of
frames between this function and the targeted class suite. 'depth'
defaults to 2, since this skips this function's frame and one calling
function frame. If you use this function from a function called directly
in the class suite, the default will be correct, otherwise you will need
to determine the correct depth yourself.
This function works by installing a special class factory function in
place of the '__metaclass__' of the containing class. Therefore, only
callbacks *after* the last '__metaclass__' assignment in the containing
class will be executed. Be sure that classes using "advising" functions
declare any '__metaclass__' *first*, to ensure all callbacks are run.z"Class advice impossible in Python3�
