53 * This program must be run from inetd. First add something like this
56 * cached_announce 3131/udp # cache announcements
58 * And then add something like this to /etc/inetd/conf:
60 * cached_announce dgram udp wait cached /tmp/recv-announce recv-announce /tmp/recv-announce.log
63 * A single instance of this process will continue to handle incoming
64 * requests. If it dies, or is killed, inetd should restart it when the
65 * next message arrives.
70 * usage: recv-announce logfile
