 	* Make.defs, namedapp/namedapp.c: Several structural changes made to get a
 	  clean compile under the ez80 ZDS-II toolchain (no design changes).
 	* apps/examples/buttons: Add a test for the new standardized button interfaces

+examples/nxtest
+^^^^^^^^^^^^^^^
+
+  This directory contains another simple test of a subset of the NX APIs
+  defined in include/nuttx/nx.h.  This text focuses on text displays on
+  the dispaly background combined with pop-up displays over the text.
+  The text display will continue to update while the pop-up is visible.
+  
+  The following configuration options can be selected:
+
+    CONFIG_EXAMPLES_NXTEXT_VPLANE -- The plane to select from the frame-
+      buffer driver for use in the test.  Default: 0
+    CONFIG_EXAMPLES_NXTEXT_DEVNO - The LCD device to select from the LCD
+      driver for use in the test: Default: 0
+    CONFIG_EXAMPLES_NXTEXT_BGCOLOR -- The color of the background.  Default
+      depends on CONFIG_EXAMPLES_NXTEXT_BPP.
+    CONFIG_EXAMPLES_NXTEXT_BGFONTCOLOR -- The color of the fonts used in the
+      background window. Default depends on CONFIG_EXAMPLES_NXTEXT_BPP.
+    CONFIG_EXAMPLES_NXTEXT_PUCOLOR -- The color of the pop-up window.  Default
+      depends on CONFIG_EXAMPLES_NXTEXT_BPP.
+    CONFIG_EXAMPLES_NXTEXT_PUFONTCOLOR -- The color of the fonts used in the
+      background window. Default depends on CONFIG_EXAMPLES_NXTEXT_BPP.
+    CONFIG_EXAMPLES_NXTEXT_BPP -- Pixels per pixel to use.  Valid options
+      include 2, 4, 8, 16, 24, and 32.  Default is 32.
+    CONFIG_EXAMPLES_NXTEXT_EXTERNINIT - The driver for the graphics device on
+      this platform requires some unusual initialization.  This is the
+      for, for example, SPI LCD/OLED devices.  If this configuration is
+      selected, then the platform code must provide an LCD initialization
+      function with a prototype like:
+
+      #ifdef CONFIG_NX_LCDDRIVER
+      FAR struct lcd_dev_s *up_nxdrvinit(unsigned int devno);
+      #else
+      FAR struct fb_vtable_s *up_nxdrvinit(unsigned int devno);
+      #endif
+
+    CONFIG_EXAMPLES_NXTEXT_BMCACHE - The maximum number of characters that
+      can be put in the background window.  Default is 128.
+    CONFIG_EXAMPLES_NXTEXT_GLCACHE - The maximum nuber of pre-rendered
+      fonts that can be retained for the background window.
+
+  This test can be performed with either the single-user version of
+  NX or with the multiple user version of NX selected with CONFIG_NX_MULTIUSER.
+  If CONFIG_NX_MULTIUSER is defined, then the following configuration
+  options also apply:
+
+    CONFIG_EXAMPLES_NXTEXT_STACKSIZE -- The stacksize to use when creating
+      the NX server.  Default 2048
+    CONFIG_EXAMPLES_NXTEXT_CLIENTPRIO -- The client priority.  Default: 100
+    CONFIG_EXAMPLES_NXTEXT_SERVERPRIO -- The server priority.  Default: 120
+    CONFIG_EXAMPLES_NXTEXT_LISTENERPRIO -- The priority of the event listener
+      thread. Default 80.
+    CONFIG_EXAMPLES_NXTEXT_NOTIFYSIGNO -- The signal number to use with
+      nx_eventnotify().  Default: 4
+
+  If CONFIG_NX_MULTIUSER is defined, then the example also expects the
+  following settings and will generate an error if they are not as expected:
+
+    CONFIG_DISABLE_MQUEUE=n
+    CONFIG_DISABLE_SIGNALS=n
+    CONFIG_DISABLE_PTHREAD=n
+    CONFIG_NX_BLOCKING=y

+#   when a new task is started. If set, all files/drivers will
+#   appear to be closed in the new task except for stdin, stdout,
+#   and stderr.
+# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
+#   desciptors by task_create() when a new task is started. If
+#   set, all sockets will appear to be closed in the new task.
+# CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
+#  handle delayed processing from interrupt handlers.  This feature
+#  is required for some drivers but, if there are not complaints,
+#  can be safely disabled.  The worker thread also performs
+#  garbage collection -- completing any delayed memory deallocations
+#  from interrupt handlers.  If the worker thread is disabled,
+#  then that clean will be performed by the IDLE thread instead
+#  (which runs at the lowest of priority and may not be appropriate
+#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
+#  is enabled, then the following options can also be used:
+# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
+#  thread.  Default: 50
+# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
+#  work in units of microseconds.  Default: 50*1000 (50 MS).
+# CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
+#  thread.  Default: CONFIG_IDLETHREAD_STACKSIZE.
+# CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up
