+^^^^^^^^^^^^^
+
+  This is a simple unit test for the TIFF creation library at apps/graphic/tiff.
+  It is configured to work in the Linux user-mode simulation and has not been
+  tested in any other environment.
+
+  At a miniumum, you would probably have to change the hard-coded pathes to
+  the TIFF files defined in the example to run in an embedded platform.

+README for the TIFF Creation Library
+=====================================
+
+This directory contains a library that can be used to create TIFF image
+files.  This file was created for the purpose of supporting screen dumps
+from an LCD.  Howeve, the logic is general and could be used for most
+any purpose.
+
+The only usage documentation is in the (rather extensive) comments in
+the file apps/include/tiff.h
