-- Little bit of Lua for building tables for the Storm and Rabiah scales.
-- Mechanics have be re-ranked in the past, and it's probably interesting to track their drift.
-- Rather than force editors to track the newest one, let's see if we can't do it in code.

	local args = frame:getParent().args -- coming from one layer up

	-- Read the arguments in the order they'll be output in, to make references number in the right order.
