Python Jabber client?

[Paul Rubin]

Is there such a thing as a general purpose Python Jabber client?  I'm
imagining one that uses tkinter.

A little Googling finds a couple of Jabber protocol libraries written
in Python, a few half-finished projects, and a client for the Sharp
Zaurus, but I didn't spot any simple portable ones that are finished
and ready to use.

If there's more than one, does anyone have a favorite?

Thanks.
