--- **AceConsole-3.0** provides registration facilities for slash commands.
-- You can register slash commands to your custom functions and use the `GetArgs` function to parse them
-- to your addons individual needs.
--
-- **AceConsole-3.0** can be embeded into your addon, either explicitly by calling AceConsole: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 AceConsole itself.\\
-- It is recommended to embed AceConsole, otherwise you'll have to specify a custom `self` on all calls you
-- make into AceConsole.
-- @class file
-- @name AceConsole-3.0
-- @release $Id$
