| # 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) |
