 On a BSD Unix, one could put "#! /bin/sh" at the start of your script
and it would work. Unfortunately, System V doesn't have this (and
worse yet, your vendor has gratuitusly hacked csh so many scripts will
break under it), so the best substitute (swiped from Perl v2's
Configure script) is:

	(alias) >/dev/null 2>&1 && (exec /bin/sh $0 ${1+"$@"})
