Like inetd, this program listens on the net for requests and spawns a server to handle them. However, it only handles one port and one program. The intended use is when you have a server that expects to be run by inetd, but you only want to run it temporarily and don't want to bother with putting it into /etc/services and /etc/inetd.conf and restarting inetd. Instead, just start up micro_inetd, and when you're done just ^C it.
