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