  wait:
    description:
      - Whether to wait for users to respond.  Module will only wait for the number of seconds specified in display_seconds or 10 seconds if not specified.
        However, if I(wait) is C(yes), the message is sent to each logged on user in turn, waiting for the user to either press 'ok' or for
        the timeout to elapse before moving on to the next user.

    description:
      - The text of the message to be displayed.
      - The message must be less than 256 characters.
    type: str
    default: Hello world!
notes:
   - This module must run on a windows host, so ensure your play targets windows
     hosts, or delegates to a windows host.
   - Messages are only sent to the local host where the module is run.
   - The module does not support sending to users listed in a file.
   - Setting wait to C(yes) can result in long run times on systems with many logged in users.
