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.
Full inetd lets you specify the socket type as one of stream, dgram, raw,
rdm, or seqpacket; micro_inetd only implements stream.
Full inetd lets you specify wait or nowait;
micro_inetd only implements nowait.
Full inetd lets you specify a user-id to run the server as;
micro_inetd doesn't try to switch user-ids.
