Asa@0 1 --- **AceAddon-3.0** provides a template for creating addon objects.
Asa@0 2 -- It'll provide you with a set of callback functions that allow you to simplify the loading
Asa@0 3 -- process of your addon.\\
Asa@0 4 -- Callbacks provided are:\\
Asa@0 5 -- * **OnInitialize**, which is called directly after the addon is fully loaded.
Asa@0 6 -- * **OnEnable** which gets called during the PLAYER_LOGIN event, when most of the data provided by the game is already present.
Asa@0 7 -- * **OnDisable**, which is only called when your addon is manually being disabled.
Asa@0 8 -- @usage

Asa@0 10 -- -- but shows usage of the callbacks.
Asa@0 11 -- local MyAddon = LibStub("AceAddon-3.0"):NewAddon("MyAddon")
