  def caveats; <<-EOS
In order for htop to display correctly all the running processes, it needs to be ran as root.

However, if you do not want to type `sudo htop` every time, you can change the owner and permissions for the executable binary:

$ cd #{prefix}/bin/
$ chmod 6555 htop
$ sudo chown root htop

  end
