Bluetooth Proximity Detector
This package is based on the package 'blueproximity' from project 'home:FunkyM'.
BlueProximity helps you add a little more security to your desktop. It does so
by detecting one of your bluetooth devices, most likely your mobile phone, and
keeping track of its distance. If you move away from your computer and the
distance is above a certain level (no measurement in meters is possible) for a
given time, it automatically locks your desktop (or starts any other shell
command you want).
