Notifications and notification plugins -------------------------------------- A notification plugin is a class that inherits from ``argus.notificationprofile.media.base.NotificationMedium``. It has a ``send(incident, user, **kwargs)`` static method that does the actual sending. The included ``argus.notificationprofile.media.email.EmailNotification`` needs only ``incident`` and ``user``, while an SMS medium in addition needs a ``phone_number``. A ``phone_number`` is a string that includes the international calling code, see for instance `Wikipedia: List of mobile telephone prefixes by country `__.
