beep - 1.4.9-1.1 main

beep does what you'd expect: it beeps. But unlike printf "\a", beep allows
you to control pitch, duration, and repetitions. Its job is to live inside
shell/perl scripts and allow more granularity than one has otherwise. It is
controlled completely through command line options. It's not supposed to be
complex, and it isn't - but it makes system monitoring (or whatever else it
gets hacked into) much more informative.
