bluemon - 1.4-10+b1 main

BlueMon monitors the quality of the link to a Bluetooth device and can start
or stop programs when the threshold drops below a certain value. This can be
used to perform actions like locking the terminal when you walk away from it.
.
Bluemon uses the DBus system bus to alert other applications to the presence
of Bluetooth devices. A user binary can then start or stop programs when such
signals are received.
