+// Class G4ParallelWeightWindowProcess
+//
+// Class description:
+//
+// Used internally by weight window technique in a "parallel" geometry.
+// This process is a forced post step process. It will apply
+// weight window biasing on collisions or on collisions and
+// boundaries according to the G4PlaceOfAction argument. 
+// It is not used in the case where it should apply only on boundaries.
