        gnuplot's Qt terminal is supported by default with the Octave GUI.
        Use other gnuplot graphics terminals by setting the environment variable
        GNUTERM in ~/.octaverc, and building gnuplot with the matching options.

          setenv('GNUTERM','qt')    # Default graphics terminal with Octave GUI
          setenv('GNUTERM','x11')   # Requires XQuartz; install gnuplot --with-x
          setenv('GNUTERM','wxt')   # wxWidgets/pango; install gnuplot --wx
          setenv('GNUTERM','aqua')  # Requires AquaTerm; install gnuplot --with-aquaterm

          You may also set this variable from within Octave.

      s += <<-EOS.undent

        You have configured Octave to use "native" OpenGL/FLTK plotting by
        default. If you prefer gnuplot, you can activate it for all future
        figures with the command
            graphics_toolkit ('gnuplot')
        or for a specific figure handle h using
            graphics_toolkit (h,'gnuplot')
      EOS
    end

    if build.head?
      s += <<-EOS.undent

        The HEAD installation activates the experimental GUI by default.
        To use the CLI version of octave, run the command "octave-cli".
      EOS
    elsif build.with? "gui"
      s += <<-EOS.undent

        The Octave GUI is experimental and not enabled by default. To use it,
        use the command-line argument "--force-gui"; e.g.,
            octave --force-gui
      EOS
      if build.with? "native-graphics"
        s += <<-EOS.undent

          Native graphics do *not* work with the GUI. You must switch to
          gnuplot when using it.
        EOS

            Octave's self-tests for this installation produced the following failues:
            --------
        EOS
        s += logs + <<-EOS.undent
            --------
            These failures indicate a conflict between Octave and its BLAS-related
            dependencies. You can likely correct these by removing and reinstalling
            arpack, qrupdate, suite-sparse421, and octave. Please use the same BLAS
            settings for all (i.e., with the default, or "--with-openblas").
