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.
Thanks,
Dave
