       This is a tool for sending an instance of gpsd commands over its control socket to add or remove devices
       from the daemon’s device list. It is not intended to be called by users, but rather by the Linux hotplug
       system and similar facilities.

       Two environment variables are interpreted.

       GPSD_SOCKET
           sets the location of the control socket. If the effective user ID of this program is root then it
           usually defaults to /run/gpsd.sock, although some systems may use the deprecated /var/run/gpsd.sock
           instead. Non-root users will use /tmp/gpsd.sock.

       GPSD_OPTIONS
           may be a list of options to be passed to gpsd when this tool launches it. It defaults to an empty
           string.

action
           may be add or remove. If no daemon instance is running when an add is requested, this program will
           launch one.

       device
           argument should be the pathname of a device. The device will be opened by gpsd to read sensor data.
