+# UPPERCASE Macro -- transform its argument to uppercase and replace dots and

+# Heavily inspired by the up macro from gmsl (http://gmsl.sf.net)

+# 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)
