-// For debug purposes the method SetCheckPointLevel can be used. If the //
-// argument is greater than 0, files with ESD events will be written after //
-// selected steps of the reconstruction for each event: //
-// level 1: after tracking and after filling of ESD (final) //
-// level 2: in addition after each tracking step //
-// level 3: in addition after the filling of ESD for each detector //
-// If a final check point file exists for an event, this event will be //
-// skipped in the reconstruction. The tracking and the filling of ESD for //
-// a detector will be skipped as well, if the corresponding check point //
-// file exists. The ESD event will then be loaded from the file instead. //
