22//config: Usually, ttys are owned by group "tty", and "write" tool is
23//config: setgid to this group. This way, "mesg y" only needs to enable
24//config: "write by owning group" bit in tty mode.
25//config:
26//config: If you set this option to N, "mesg y" will enable writing
27//config: by anybody at all. This is not recommended.
