All periodic sub-scripts <larf> now have their return codes interpreted
by periodic(8). Output may be masked based on variable values in
periodic.conf.
It's also now possible to email periodic output to arbitrary addresses,
or to send it to a log file, examples of which can be found in
newsyslog.conf.
The upshot of it all should be no discernable changes to the default
behaviour of periodic(8).

The only change in the default functionality should be that
the output reports are slightly more verbose WRT files deleted.

rwho iff /var/rwho is empty. Call `uptime' instead. This doesn't
belong under `network' right away, but at least reports the same
informaton about the local system. rwhod is not turned on by default
(for good reason), and i've already seen too many of the above
messages...
