Anything which uses kvm should accept the -N <nlistf> option, which points
to a file to take the symbol name list from (for lookup of a datum based on
a symbol name), and a -M <memf> option, which points to a file to take core
memory from, such as a core memory dump, or system-in-a-memory-image
setup.
Just for the sake of verbosity and actually pointing to something one
can do, rather than expecting someone to figure out that those flags
exist, etc.
Here's an example:
