+	---help---
+		Many LCD hardware interfaces provide only minimal graphics capability.  In
+		particulary, many simple LCD interfaces are write only.  That is we, can
+		write graphics data to the LCD device memory, but we cannot read it back.
+		If the LCD hardware does not support reading the graphics memory, then
+		this option should be defined so that the NX layer can taking alternative
+		measures when the LCD is not readable.  For example, if the LCD is not
+		readable, then NX will not attempt to support transparency.
+
+		See also NX_WRITEONLY in the graphics support menu.
