To install, you will need custom installs of fltk and graphicsmagick:
brew install --HEAD fltk
brew install graphicsmagick --with-magick-plus-plus
To omit these features, see "brew options octave"
EOS
native_caveats = <<-EOS.undent
Octave 3.4.0 supports "native" plotting using OpenGL and FLTK. You can activate
it for all future figures using the Octave command
graphics_toolkit ("fltk")
or for a specific figure handle h using
graphics_toolkit (h, "fltk")
Otherwise, gnuplot is still used by default, if available.
EOS
gnuplot_caveats = <<-EOS.undent
When plotting with gnuplot, you should set "GNUTERM=x11" before running octave;
if you are using Aquaterm, use "GNUTERM=aqua".
EOS
s = gnuplot_caveats
s = native_caveats + s unless no_native?
