@vadler This needs to be backported in order to have the signal definitions based on this tool available in the current CMSSW_7_X release. This would also simplify installation instructions for the TWiki that is being prepared for the tool.

[vadler]

@bartosik-desy : I guess, what you mean is, that this uses a feature correctly now, which is standard in the 7XY series anyway, right?

[bartosik-hep]

@vadler Yes, of course. It is using the official JetFlavour tool for matching hadrons to jets instead of custom implementation that is present in the current 7_2_X release.
