==> Caveats
mtr requires superuser privileges. You can either run the program
via `sudo`, or change its ownership to root and set the setuid bit:
sudo chown root:wheel /usr/local/Cellar/mtr/0.82/sbin/mtr
sudo chmod u+s /usr/local/Cellar/mtr/0.82/sbin/mtr
In any case, you should be certain that you trust the software you
are executing with elevated privileges.
