## This is a quick example listen-exec server, which was used for a while to
## distribute netcat prereleases. It illustrates use of netcat both as a
## "fake inetd" and a syslogger, and how easy it then is to crock up a fairly
## functional server that restarts its own listener and does full connection
## logging. In a half-screen of shell script!!
