-- This is a default script to be executed by Artemis.
-- You do not need to use this if you don't want to script. The default profiles
-- should provide you with a lot of functionality out of the box.
-- However, if you want to change the way profiles work, this is the ideal way
-- go about it.

-- For docs and examples, see wiki: https://github.com/SpoinkyNL/Artemis/wiki/LUA

-- Note: You are editing a temporary file. Whenever you save this file the
-- changes are applied to the profile and the script is restarted.

-- This event is raised after every profile update, before drawing.
