zshutdown_notify - notify users of impending shutdown via Zephyr
zshutdown_notify reads the standard input until EOF is reached, and
then sends a Zephyr notice with the official hostname, the collected
input, and a warning message as the message body of the notice. The
notice is sent to class FILSRV, instance <hostname>, recipient "*",
where <hostname> is the official hostname of the sending host.
Any users who are using resources on the sending host are expected to
subscribe to these messages so they will be warned of any impending
zshutdown_notify is usually invoked from within /etc/shutdown.
