- # 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)
