usage: gpsd [-b] [-n] [-N] [-D n] [-F sockfile] [-G] [-P pidfile] [-S port] [-h] device...
Options include:
-b = bluetooth-safe: open data sources read-only
-n = don't wait for client connects to poll GPS
-N = don't go into background
-F sockfile = specify control socket location
-G = make gpsd listen on INADDR_ANY
-P pidfile = set file to record process ID
-D integer (default 0) = set debug level
-S integer (default 2947) = set port for daemon
-h = help message
-V = emit version and exit.
A device may be a local serial device for GPS input, or a URL in one
of the following forms:
tcp://host[:port]
udp://host[:port]
{dgpsip|ntrip}://[user:passwd@]host[:port][/stream]
gpsd://host[:port][/device][?protocol]
in which case it specifies an input source for device, DGPS or ntrip data.
