> PING    (/usr/lib/python2.7/site-packages/ansible-2.8.0.dev0-py2.7.egg/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 that requires Python on the
        remote-node. For Windows targets, use the [win_ping] module instead. For Network
        targets, use the [net_ping] module instead.

  * This module is maintained by The Ansible Core Team
OPTIONS (= is mandatory):

NOTES:
      * For Windows targets, use the [win_ping] module instead.
      * For Network targets, use the [net_ping] module instead.
