+--- **AceAddon-3.0** provides a template for creating addon objects.
+-- It'll provide you with a set of callback functions that allow you to simplify the loading
+-- process of your addon.\\
+-- Callbacks provided are:\\
+-- * **OnInitialize**, which is called directly after the addon is fully loaded.
+-- * **OnEnable** which gets called during the PLAYER_LOGIN event, when most of the data provided by the game is already present.
+-- * **OnDisable**, which is only called when your addon is manually being disabled.
+-- @usage
+-- -- A small (but complete) addon, that doesn't do anything, 
+-- -- but shows usage of the callbacks.
+-- local MyAddon = LibStub("AceAddon-3.0"):NewAddon("MyAddon")
+-- 
+-- function MyAddon:OnInitialize()
+--   -- do init tasks here, like loading the Saved Variables, 
+--   -- or setting up slash commands.
+-- end
+-- 
+-- function MyAddon:OnEnable()
+--   -- Do more initialization here, that really enables the use of your addon.
+--   -- Register Events, Hook functions, Create Frames, Get information from 
+--   -- the game that wasn't available in OnInitialize
+-- end
+--
+-- function MyAddon:OnDisable()
+--   -- Unhook, Unregister Events, Hide frames that you created.
