Hi,
There are a few books whitch mention it.

Another really inexpensive book by tracy barker I remember as good ( but unfortunately cannot locate in my bookshelvesI think had some good info )
Or of course the grand daddy of them all - http://vpi.com/store/products/python...ing_in_usa_can
(page 228 )
But on the whole there should be enough info on t'interwebs to get you on the right track.
