Launchpad Project Bug Lister with Milestones

buglist.py

#!/usr/bin/env python


#
# Lists Launchpad bugs in the console showing their targetted milestone
#
# Usage: python buglist.py [project_name]
#
# I created this when I couldn't find a way to list the bugs in Keystone and
# show their targetted milestones so I could shuffle them around
