  23 // Set of classes defining the ALICE RAW event format. The AliRawEvent  //
  24 // class defines a RAW event. It consists of an AliEventHeader object   //
  25 // an AliEquipmentHeader object, an AliRawData object and an array of   //
  26 // sub-events, themselves also being AliRawEvents. The number of        //
  27 // sub-events depends on the number of DATE LDC's.                      //
  28 // The AliRawEvent objects are written to a ROOT file using different   //
  29 // technologies, i.e. to local disk via AliRawDB or via rfiod using     //
  30 // AliRawRFIODB or via rootd using AliRawRootdDB or to CASTOR via       //
  31 // rootd using AliRawCastorDB (and for performance testing there is     //
  32 // also AliRawNullDB).                                                  //
  33 // The AliStats class provides statics information that is added as     //
  34 // a single keyed object to each raw file.                              //
  35 // The AliTagDB provides an interface to a TAG database.                //
  36 // The AliMDC class is usid by the "alimdc" stand-alone program         //
  37 // that reads data directly from DATE.                                  //
