  module: awall
  short_description: Manage awall policies
  version_added: "2.4"
  author: Ted Trask (@tdtrask) <ttrask01@yahoo.com>
  description:
    - This modules allows for enable/disable/activate of I(awall) policies.
      Alpine Wall (I(awall)) generates a firewall configuration from the enabled policy files
      and activates the configuration on the system.
  options:
    name:
      description:
        - A policy name, like C(foo), or multiple policies, like C(foo, bar).
      default: null
    state:
      description:
        - The policy(ies) will be C(enabled)
        - The policy(ies) will be C(disabled)
      default: enabled
      choices: [ "enabled", "disabled" ]
    activate:
      description:
        - Activate the new firewall rules. Can be run with other steps or on it's own.
      default: False
