+# NOTE on the subdirectory structures here:
+#
+# - "inc" provides local header files shared between the coveragetest,
+#    wrappers, and overrides source code units
+# - "coveragetest" contains source code for the actual unit test cases
+#    The primary objective is to get line/path coverage on the FSW 
+#    code units.
