## Add your info to the varibles below, don't foreget to make the script executable      ##
## For use on Ubuntu 10.04, Version 1.1                                                  ##

## Ubuntu 9.10 can use this script, but must install pulseaudio-module-bluetooth         ##
## and load module-bluetooth-discover using pactl load-module module-bluetooth-discover  ##
