paxmark - a utility for setting PaX markings on binaries

Usage:
% paxmark -[pP|eE|mM|rR|sS] <binary>

Each letter corresponds to a PaX feature flag, upper case
enabling and lower case disabling.

This utility will clear out invalid marks and explicitly set
enabled for missing marks, matching defaults.
