// Program can used to dump the raw-data files in ROOT format.          //
// It dumps the event,sub-event,equipment and common-data header.       //
// Additional application of the program is to check if the CDHs        //
// of different raw-data payloads are compatible. In this sense         //
// it replaces the DAQ online checks in case the DAQ is running         //
// UNCHECKED partition.                                                 //
