Hi Stephane,

Do you need these ``import *`` lines?  In general, it is much better to import only the symbols which are absolutely needed, i.e.

```python
from PhysicsTools.PatAlgos.tools.jetTools import jet_helper
```

or whatever it is you need to use.  If you do it the import * way, you pollute the global namespace of this module and any cms.Process which touches it.
