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.
WPrefs --version (return code: 0)
WPrefs (Window Maker) 0.95.8
WPrefs --help (return code: 0)
usage: WPrefs [options]
-display <display> display to be used
--version print version number and exit
--help print this message and exit
