Andrea,

It's not too bad. Ewoud pointed you to the socket interface; it's as
simple as opening a socket, listening for a message, and once received,
close the socket. Loop around and do it again.

You might also want to listen for a 'special' message such as "SHUT DOWN
NOW" which tells the program to shut itself down gracefully. Otherwise
you would have to kill. Not that this *should* cause a problem - but
I'm always in favor of graceful shutdowns :-).
