Python 2.2 class methods examples?

[Mark Brady]

Hi. I've just moved to 2.2 and I think I've got my head around most of
the cool new features but I can't see what class methods would be used
for. I understand the difference between them and static methods and I
know where static methods are useful but it would be great if someone
could post an example of class method usage or some links. Thanks.

Mark.
