+// This is the future base for managing the clusters in barrel detectors.
+// It is fully interfaced with the ROOT geometrical modeller TGeo.
+// Each cluster contains XYZ coordinates in the local tracking c.s. and
+// the unique ID of the sensitive detector element which continas the
+// cluster. The coordinates in global c.s. are computed using the interface
+// to TGeo and will be not overwritten by the derived sub-detector cluster
+// classes.
