-// *** Class AliRsnEvent ***
-//
-// A container for a collection of AliRsnDaughter objects from an event.
-// Contains also the primary vertex, useful for some cuts.
-// In order to retrieve easily the tracks which have been identified
-// as a specific type and charge, there is an array of indexes which
-// allows to avoid to loop on all tracks and have only the neede ones.
-//

-// M. Vala (email: martin.vala@cern.ch)
+// Interface to full event.
