+pascal/nuttx/README.txt
+^^^^^^^^^^^^^^^^^^^^^^^
+
+This directory contains miscellaneous files needed to install the pascal
+runtime logic into the NuttX apps/ ource tree.  After installation, the NuttX
+apps/ source tree contain the following files
+
+  pcode
+  |-- Makefile
+  |-- include
+  |   `-- Common header files
+  |-- libboff
+  |   `-- Pascal object format (POFF) library
+  `--insn
+      |-- include
+      |   `-- model-specific header files
+      `-- prun
+          `-- model-specific source files
+
+This directory contains:
+
+  INSTALL.sh -- The script that performs the operation.  Usage:
+
+    ./INSTALL.sh [-16|-32] <install-dir>
+
+    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.
+
+    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.
+
+  keywords.h -- A version that adjusts build context for the NuttX
+    build environment.
