+	  Note: this Buildroot package does not include the graphical
+	  user interface. It is meant to be executed as a headless
+	  daemon to be controlled with MIDI events or network OSC
+	  (Open Sound Control) events. OSC events can be generated
+	  from an external system with the ZynAddSubFX external GUI
+	  program zynaddsubfx-ext-gui.
