+# This script removes branch and/or line coverage data for lines that
+# contain a particular substring.
+#
+# 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.
