HELP='Usage:
  quiet fname cmd args ...

Runs the  passed in command  printing only  "cmd" and "fname"  unless an
error  occurs  in which  case  it  prints  the  whole command  line  and
colorized program output. Useful  for running compilation commands since
it removes the cluter, making it easier to spot errors and warnings.
