+       [@w{#:auto-enable? #f}]
+Return a service that runs the @command{bluetoothd} daemon, which
+manages all the Bluetooth devices and provides a number of D-Bus
+interfaces.  When AUTO-ENABLE? is true, the bluetooth controller is
+powered automatically at boot, which can be useful when using a
+bluetooth keyboard or mouse.
 
 Users need to be in the @code{lp} group to access the D-Bus service.
