Re: [Crash-utility] [PATCH] Add missing help options to the option list

The -g and -N options should be added, and although -z is essentially a shortened version of "help help", I suppose it could be added as well. However, the -O option is a remnant from many years ago when I attempted to allow the creation of a file of kernel-version-specific offsets, sizes, etc, from a vmlinux file built with -g, and then subsequently using that file with a stripped vmlinux file of the same version. (It was an idea from back in the RHEL2.1 days, which released a vmlinux file that was stripped of debuginfo data.) Anyway, that code was never truly functional, and is just leftover cruft.
