[root@m01 ~]# ansible-doc -v ping
 Using /etc/ansible/ansible.cfg as config file
 > PING (/usr/lib/python2.6/site-packages/ansible/modules/system/ping.py)
 A trivial test module, this module always returns `pong' on successful contact. It does not make sense in playbooks, but it is useful from `/usr/bin/ansible' to verify the ability to login and that a usable python is configured. This is NOT ICMP ping, this is just a trivial test module.
