  def caveats; <<-EOS.undent
    htop-osx requires root privileges to correctly display all running processes.
    You can either run the program via `sudo` or set the setuid bit:

      sudo chown root:wheel #{bin}/htop
      sudo chmod u+s #{bin}/htop

    You should be certain that you trust any software you grant root privileges.
