Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
spacenavd -V (return code: 1)
unexpected argument: --version
spacenavd -h (return code: 0)
usage: spacenavd [options]
-d do not daemonize
-v verbose output
-h print this usage information
