Revision 1.3  2001/03/16 09:48:35  morsch
Exclude pdg particle definitions. Done by root now by default from Pythia6 table.

Revision 1.2  2001/01/31 14:32:42  morsch
Some B mesons added

Revision 1.1  2000/12/21 16:48:39  morsch
AliPDG class, first commit.

// Class to encapsulate the ALICE updates to TDatabasePDG.h
// Can be used by TGeant3 and TGeant4
// It contains also the constants for the PDG particle IDs.
// Should evolve towards dynamical loading from external data base.
