-Revision 1.7.10.1 2002/06/10 14:57:41 hristov
-Merged with v3-08-02
-
-Revision 1.10 2002/05/02 09:40:50 morsch
-Recover mods from Rev. 1.8
-
-Revision 1.9 2002/04/23 12:54:29 morsch
-New options kPi0Flat y kEtaFlat (Gustavo Conesa)
-
-Revision 1.7 2001/03/09 13:01:41 morsch
-- enum constants for paramterisation type (particle family) moved to AliGen*lib.h
-- use AliGenGSIlib::kUpsilon, AliGenPHOSlib::kEtaPrime to access the constants
-
-Revision 1.6 2000/11/30 07:12:50 alibrary
-Introducing new Rndm and QA classes
-
-Revision 1.5 2000/06/29 21:08:27 morsch
-All paramatrisation libraries derive from the pure virtual base class AliGenLib.
-This allows to pass a pointer to a library directly to AliGenParam and avoids the
-use of function pointers in Config.C.
-
-Revision 1.4 2000/06/14 15:21:05 morsch
-Include clean-up (IH)
