  # After the instances are launched, you can switch to another playbook to manipulate them
  # if you're using the ec2.py inventory source. If not, you can use add_host to add them
  # to a temporary inventory group right in this playbook, and target them that way. See
  # http://docs.ansible.com/guide_aws.html for more details.
