-- Additional debug info can be found on http://www.wowwiki.com/Blizzard_DebugTools
-- /framestack [showhidden]
--		showhidden - if "true" then will also display information about hidden frames
-- /eventtrace [command]
-- 		start - enables event capturing to the EventTrace frame
--		stop - disables event capturing
--		number - captures the provided number of events and then stops
--		If no command is given the EventTrace frame visibility is toggled. The first time the frame is displayed, event tracing is automatically started.
-- /dump expression
--		expression can be any valid lua expression that results in a value. So variable names, function calls, frames or tables can all be dumped.

-- Adds message to the chatbox (only visible to the loacl player)
