    # You don't have to use $.ajax as your action, messenger works
    # great for any async process:

        action: defuseBomb
        # You can put options for defuseBomb here
        # It will be passed success and error callbacks
    # Need to hide all messages?
    # If your action responds with a promise-like thing, its
    # methods will be copied onto the message:
    Messenger().run({}, {url: 'a'}).fail(-> alert "Uh oh")
    # Do you use Backbone? Hook all backbone calls:
    # By default, there will be no error message (just background
    # retries), return an error message from your backbone error handler,
    # or add an errorMessage to the messenger opts to set one.
    # You can override these options by passing them into
    # hookBackboneAjax, or adding a {'messenger': } hash to your
    # fetch call.
    # You don't have to use the global messenger
    $('div#message-container').messenger().post "My message"
    # By default, the global messenger will create an ActionMessenger
    # instance fixed to the bottom-right corner of the screen.
    # You can pass an instance of messenger into globalMessenger
    # to override the default position.
    myAwesomeMessenger = $('.mess').messenger()
    Messenger({instance: myAwesomeMessenger});
    Messenger() # <-- Will return your messenger
    Messenger({'parentLocations': ['.page', 'body']});
    # Will try to insert the messenger into the el matching
    # .page before inserting it into the page.
    # This can be important if you're not using fixed positioning.
    # All the options for globalMessenger and their defaults:
      'parentLocations': ['body'],
      'maxMessages': 9,
      'extraClasses': 'messenger-fixed messenger-on-right messenger-on-bottom messenger-theme-future',
      'instance': undefined,
      'messageDefaults': {

    # You can also set default options on the Messenger.options object.
