ah, ok. it is not 4 options (-s, -a, -f, and -e), but one (-safe, as in
"not in danger"). that's why it is described as a "...first (and not
very reliable) approximation to a ``safe'' version of awk."
you are confusing that with the -f option, which does require an
argument: [prog | -f progfile]
hence:
[-safe] [-V]
and not the more usual:
[-safeV]
hope that's clear ;)
