wireless killswitch management daemon for laptops

 The urfkill daemon allow managing the rfkill-related hotkeys
 and the killswitches in a more configurable way for the common RF
 devices (WiFi, Bluetooth, WWan...). It handles the various
 key codes (KEY_WLAN, KEY_BLUETOOTH, KEY_RFKILL...)
 and toggles the killswitches based on a pre-defined policy.
