-Makefile -- The NuttX makefile for the runtime logic
+    If you are using the standard NuttX apps/ package, the correct
+    location for the <install-dir> is apps/interpreters.  That is
+    where the examples and build logic will expect to find the pcode
+    sub-directory.
 
-keywords.h -- A version that adjusts build context for the NuttX
-  environment.
+    Example:
+
+    ./INSTALL.sh -16 $PWD/../../../apps/interpreters
+
+  Makefile -- The NuttX makefile for the runtime logic.  This makefile
+    is customized to work in the standard apps/ package.  If you intend
+    to use your own custom apps/ directory, then this Makefile may
+    require some modifications.
