+
+Modifications:
+- the python version has been frozen to python2,
+  as the script is not python3-compatible
+- added -warnings-as-errors option
+- the run-clang-tidy.py script has been modified
+  to return a sensible exit code when running on Travis CI,
+  i.e. it honors exit code of the underlying processes
+  causing build failures on pull requests
