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.
xpce-client -V (return code: 2)
connect: Connection refused
xpce-client (return code: 1)
Usage: xpce-client file|host:port [-q] [-[b]c message]
