+// Abstract interface for GEANT4 Global Fast Simulation Manager.
+// P. Mora de Freitas & M. Verderi 14/April/1999.
+//
+// G4GlobalFastSimulationManager is a "Singleton", i.e., only one instance 
+// of it may exist. This is ensured by making the constructor private.
+//
+// G4VGlobalFastSimulationManager is an abstract interface for the
+// G4GlobalFastSimulationManager one. It has the public access function
+// GetConcreteInstance(), which is used to obtain a pointer to the concrete 
+// G4GlobalFastSimulationManager, should it exist. After
+//
+// G4VGlobalFastSimulationManager* pVFSMan =  
+//     G4VGlobalFastSimulationManager::GetConcreteInstance ();
+//
+// pVFSMan points to the real (concrete) G4GlobalFastSimulationManager if
+// at least a parameterisation envelope exists, otherwise is zero.  
+//
+// Thus all code must be protected, for example by:
+//   if (pVFSMan) 
+//    G4FlavoredParallelWorld* =
+//      pVFSMan -> GetFlavoredWorldForThis(p);
