+# 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.
+#
+
+# Use the UT assert public API, and allow direct
+# inclusion of source files that are normally private

+# Add a coverage test executable called "sample_app-ALL" that 
+# covers all of the functions in sample_app.  
+#
+# Also note in a more complex app/lib the coverage test can also
+# be broken down into smaller units (in which case one should use
+# a unique suffix other than "ALL" for each unit).  For example,
+# OSAL implements a separate coverage test per source unit.
