  # helpmaster: `publish announcements`
  # helpmaster:    It will publish on all channels the announcements added by using 'add announcement' command.
  # helpmaster:    Only works if you are on Master channel and you are a master admin user
  # helpmaster:    The messages stored on a DM won't be published.
  # helpmaster:    This is very convenient to be called from a *Routine* for example every weekday at 09:00.
