+On Fremantle only, autostart_microb controls whether MicroB is
+prestarted when the device boots. By default, MicroB is prestarted only
+when MicroB is set as the default browser; you can force MicroB to
+always prestart by setting autostart_microb = 1, while you can force it
+to never prestart by setting autostart_microb = 0. [This option has no
+corresponding UI at the moment.]
