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.
kbd_mode -V (return code: 0)
kbd_mode from kbd 1.15.5
kbd_mode --help (return code: 1)
kbd_mode: invalid option -- '-'
usage: kbd_mode [-a|-u|-k|-s] [-C device]
