# This script demonstrates how to use host aggregates:
#
# * Create an Aggregate
# * Updating Aggregate details
# * Testing Aggregate metadata
# * Testing Aggregate delete
# * Testing General Aggregates (https://blueprints.launchpad.net/nova/+spec/general-host-aggregates)
# * Testing add/remove hosts (with one host)
