 // Class G4VSampler

 // Class description:
-// The base class for importance sampling and scoring. 
-// 
+//
+// This interface discribes a configurable sampler.
+// It applies to a given particle type.
+// Concrete classes with this interface may be used for 
+// scoring, importance sampling and weigth cutoff (weight roulett).
