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.
gbsinfo -VERSION (return code: 0)
gbsinfo --help (return code: 1)
gbsinfo: invalid option -- '-'
Usage: gbsinfo [option] <gbs-file>
Available options are:
-h display this help and exit
-V print version and exit
