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.
gpsfake -V (return code: 1)
gpsfake: option --version not recognized
gpsfake -h (return code: 0)
usage: gpsfake [-h] [-l] [-m monitor] [--D debug] [-o options] [-p] [-s speed] [-S] [-c cycle] [-b] logfile
