  # NEURON uses .la files to compile HOC files at runtime

  # 1. The build fails (for both gcc and clang) when trying to build
  #    src/mac/mac2uxarg.c, which uses Carbon.
  #    According to the lead developer, Carbon is not available for 64-bit
  #    machines, and is an "ancient launcher helper", so we remove it,
  #    as was suggested in this forum thread:
  #       http://www.neuron.yale.edu/phpbb/viewtopic.php?f=4&t=3254
  # 2. The build assumes InterViews kept .la files around. It doesn't,
  #    so we link directly to the .dylib instead.

  def caveats; <<-EOS.undent
    NEURON recommends that you set an X11 option that raises the window
    under the mouse cursor on mouseover. If you don't set this option,
    NEURON's GUI will still work, but you will have to click in each window
    before you can interact with the widgets in that window.

    To raise the window on mouse hover, execute:
        defaults write org.macosforge.xquartz.X11 wm_ffm -bool true
    To revert this behavior, execute:
        defaults write org.macosforge.xquartz.X11 wm_ffm -bool false
    EOS
  end

    system "#{bin}/nrniv", "--version"
