* To enable multi-region support.

- To use a region other than the default one.
  Auth API version default is v2.0 (no Tenant)
  Note: Ensure Cloud Server region match for ServiceNet to work.

- Sample region override:
  conn = cloudfiles.get_connection('jsmith', '1234567890', \
                                         storage_region='DFW')

- Revert to Auth v1.0 (rather then v2.0)
  conn = cloudfiles.get_connection('jsmith', '1234567890', \
                                         auth_version='1.0')
