protocol for external scripts. Now that Mike has been successfully
embarrased in front of everyone, I will document said protocol:

	$status < 0 - Fatal error. Email output to tbops.
	$status = 0 - Everything okay!
	$status > 0 - Expected error. Give results to user only.

Of course, only 4 scripts have been adapted to the new protocol, but
thats okay. I'm sure Mike will trip over them all eventually.
