/**
 * @file HLToutputTodHLTRootObjects.C
 * @brief Macro for converting dHLT output in HLTOUT into ROOT objects or dumping to file.
 *
 * This macro converts dHLT output data blocks in HLTOUT to dHLT ROOT
 * objects which can be used for dHLT specific analysis or debugging.
 * Alternatively the dHLT data blocks are dumped to file in raw binary format.
 *
 * @note The macro must be run in the directory with the raw0, raw1 etc
 * directories. Also no reconstructed ROOT files should be in this directory
 * either. Backup any reconstructed AliESDs.root files if you want, and then
 * delete all root files in the directory where you will run this macro.
 *
 * @param dataSource  Indicates where to find the raw data. If this is a path
 *      then the raw data is expected to be in DDL file format stored in directories
 *      called raw0, raw1 and so on.
 *      If a file name is given instead then it is assumed to be a DATE file unless
 *      it ends in ".root", in which case it is assumed to be rootified raw data.
 * @param dumpBinary  Indicates if the data should be dumped in raw binary format
 *      to files with the file name prefix "output-". If set to false then the
 *      output is rootified and written to a ROOT file "output.root".
