-Introducing Riostream.h
+/* $Id$ */
-Revision 1.4 2000/11/20 21:44:17 pcrochet
-some modifications to account for the new class AliMUONResponseTriggerV1
-Revision 1.3 2000/07/03 11:54:57 morsch
-AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
-The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
