 | --configKeyValues | Like `--configFile` but allowing to set parameters on the command line as a string sequence. Example `--configKeyValues "Stack.pruneKine=false"`. Takes precedence over `--configFile`. Parameters need to be known ConfigurableParams. |
 | --seed   | The initial seed to (all) random number instances. Default is -1 which leads to random behaviour. |
 | -o,--outPrefix | How output files should be prefixed. Default is o2sim. Example `-o mySignalProduction`.|
