# An example of how to use AWS SNS with Python's boto
# By Stuart Myles @smyles
# http://aws.amazon.com/sns/
# https://github.com/boto/boto
#
# Inspired by parts of the Ruby SWF SNS tutorial http://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-sns-tutorial-implementing-activities-poller.html
# And the Python SNS code in http://blog.coredumped.org/2010/04/amazon-announces-simple-notification.html and http://awsadvent.tumblr.com/post/37531769345/simple-notification-service-sns
