This universe generates a chirp (a sinusoid with slowly increasing
frequency) and plays it over the workstation speaker.
It does this by writing its output to a temporary file and invoking
the "play" program
on that file.  On a sparcstation equipped with a speaker, this will
produce sound.  This will also work on any other workstation if
a compatible "play" program is in the users path.
