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.
vmcore-dmesg -V (return code: 3)
Read of e_ident from --version failed: Success
vmcore-dmesg (return code: 1)
usage: vmcore-dmesg <kernel core file>
