Quote from TorhalMapster is pretty bare-bones, to be honest - and Ace isn't an acronym. If you think having an "Ace dependency" is a serious issue, you have other problems.
I don't need Mapster. I have no need of Ace in my 8Kb addon. I simply looked in code of Mapster for solution of my problem. I asked only for help with specific problem (because i am newbie to lua).
