Can somebody PLEASE improve on the code below?
I mean... "require 'fox'" should just do it.
I know RUBY_OPTIONS can help with gems, but this fox vs fox12 stinks, too.
.... and this FOXVERSION and aliasing stuff... man, horrible.

Note I use neither gems nor fox, but if this is 'normal' to get it
working, I ain't gonna use them!!

(at least put the line "include Fox" below the rest, only once instead of
three times...)
