+
+Roadmap
+^^^^^^^
+
+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.
+  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.
+  NX        - The tiny NuttX windowing system.  This includes both a small-footprint,
+              single user implementaton (NXSU as described below) and a somewhat
+              larger multi-user implentation (NXMU as described below).  Both
+              conform to the same APIs as defined in include/nuttx/nx.h and, hence,
+              are more-or-less interchangable.  NX can be used without NXWIDGETS
+              and without NXTOOLKIT for raw access to window memory.
+  NXGLIB    - Low level graphics utilities and direct framebuffer rendering logic.
+              NX is build on NXGLIB.
+
+Directories:
+^^^^^^^^^^^^
+
+graphics/nxglib
+  The NuttX tiny graphics library.  The directory contains generic utilities
+  support operations on primitive graphics objects and logic to rasterize directly
+  into a framebuffer.  It has no concept of windows (other than the one, framebuffer
+  window).
+
+graphics/nxbe
+  This is the "back-end" of a tiny windowing system.  It can be used with either of
+  two front-ends to complete a windowing system (see nxmu and nxsu below).  It
+  contains most of the important window management logic:  clipping, window controls,
+  window drawing, etc.
+
+graphics/nxsu
+  This is the NX single user "front end".  When combined with the generic "back-end"
+  (nxbe), it implements a single thread, single user windowing system.  The files
+  in this directory present the window APIs described in include/nuttx/nx.h.  The
+  single user front-end is selected when CONFIG_NX_MULTIUSER is not defined in the
+  NuttX configuration file.
+
+graphics/nxsu
+  This is the NX multi user "front end".  When combined with the generic "back-end"
+  (nxbe), it implements a multi-threaded, multi-user windowing system.  The files
+  in this directory present the window APIs described in include/nuttx/nx.h.  The
+  multi-user front end includes a graphics server that executes on its own thread;
+  multiple graphics clients then communicate with the server via a POSIX message
+  queue to serialize window operations from many threads. The multi-user front-end
+  is selected when CONFIG_NX_MULTIUSER is defined in the NuttX configuration file.
