+# This script removes branch and/or line coverage data for lines that

+#
+# In the interest of "fairness" it removes all branch or coverage data
+# when a match is found -- not just negative data.  It is therefore
+# likely that running this script will actually reduce the total number
+# of lines and branches that are marked as covered (in absolute terms).

+# This script intentionally avoids checking for errors.  Any exceptions
+# will trigger make to fail.
