  def caveats; <<-EOS.undent
      GMT 5 is mostly (but not 100%) compatible with previous versions.
      Moreover, the compatibility mode is expected to exist only during a
      transitional period.

      If you want to continue using GMT 4:
      `brew install gmt4`

      We agreed to the `triangle` license
      (http://www.cs.cmu.edu/~quake/triangle.html) for you.
      If this is unacceptable you should uninstall.
