+--- AceEvent-3.0 provides event registration and secure dispatching.
+-- All dispatching is done using **CallbackHandler-1.0**. AceEvent is a simple wrapper around
+-- CallbackHandler, and dispatches all game events or addon message to the registrees.
+--
+-- **AceEvent-3.0** can be embeded into your addon, either explicitly by calling AceEvent:Embed(MyAddon) or by 
+-- specifying it as an embeded library in your AceAddon. All functions will be available on your addon object
+-- and can be accessed directly, without having to explicitly call AceEvent itself.\\
+-- It is recommended to embed AceEvent, otherwise you'll have to specify a custom `self` on all calls you
+-- make into AceEvent.
