# UPPERCASE Macro -- transform its argument to uppercase and replace dots and
# hyphens to underscores
# Heavily inspired by the up macro from gmsl (http://gmsl.sf.net)
# This is approx 5 times faster than forking a shell and tr, and
# as this macro is used a lot it matters
# This works by creating translation character pairs (E.G. a:A b:B)
# and then looping though all of them running $(subst from,to,text)
