EXAMPLES = '''
- bigpanda: component=myapp version=1.3 token={{ bigpanda_token }} state=started
...
- bigpanda: component=myapp version=1.3 token={{ bigpanda_token }} state=finished

or using a deployment object:
- bigpanda: component=myapp version=1.3 token={{ bigpanda_token }} state=started
  register: deployment

- bigpanda: state=finished
  args: deployment

If outside servers aren't reachable from your machine, use local_action and pass the hostname:
- local_action: bigpanda component=myapp version=1.3 hosts={{ansible_hostname}} token={{ bigpanda_token }} state=started
  register: deployment
...
- local_action: bigpanda state=finished
  args: deployment
