51    @brief
52        A Notification represents a short message used to inform the player about something that just happened. With the @ref orxonox::NotificationManager "NotificationManager" a Notification can be sent from any part of orxonox and is then displayed by the proper @ref orxonox::NotificationQueue "NotificationQueue(s)" (depending on which senders the specific @ref orxonox::NotificationQueue "NotificationQueues" accepts).
53
54        A Notification is just a data structure that is used internally by the Notifications module.
