 This directory holds NuttX graphic packages.  Not all of these packages are implemented
 at the present, but here is the longer term roadmap:
 
-  NXWIDGETS - A high level, C++, object-oriented library for object-oriented access
-              to graphics widgets.  NXWIDGETS is built on top of NXTOOLKIT and NX.
+  NXWIDGETS - I had originally planned a high level, C++, object-oriented library for
+              object-oriented access to graphics widgets.  However, because C++ compilers
+              are not available for some of the targets supported by NuttX, I have
+              decided to implement the entire solution in  C -- that makes the solution
+              much uglier, but works fine on all platforms.
   NXTOOLKIT - A set of C graphics tools that provide higher-level window drawing
               operations.  The toolkit can be used for window-oriented graphics
               without NXWIDGETS and is built on top of NX.
