FedEX Tracking Information (Python recipe) by Chris Moffitt

ActiveState Code (http://code.activestate.com/recipes/259097/)

"""
This script uses the FedEx web site to download tracking information
from the web form.

Current version has US and English hardcoded in the URL.  Should be trivial to modify to support other locations/locales.
