-# HERE COME TWO OPTIONS, WHICH ALLOW ACOUSTIC SIGNALS on the server beeper WHEN AN EMAIL IS ACTUALLY SENT OUT.
-# YOU MIGHT WISH TO ENABLE THESE, BUT BE CAREFUL, AS A system() CALL IS PERFORMED using the shown parameters.
-# I FIND IT VERY USEFUL, but this is a very personal comment. T. Gries

-# The system speaker beeps when the wiki actually sends out a notification mail (safe default = disabled).
-#
-# The following string is passed as parameter to a system() call in UserMailer.php
-# The system() calls call - in the shown example - the beep 1.2.2 program (LINUX) with frequency f [Hz] and length l [msec]
-#
-# Beep 1.2.2 can be found on http://freshmeat.net/projects/beep/ and I like it.
