+Revision 1.37 2002/10/22 14:45:47 alibrary
+Introducing Riostream.h
+
+Revision 1.36 2002/10/14 14:57:08 hristov
+Merging the VirtualMC branch to the main development branch (HEAD)
+
+Revision 1.35.10.2 2002/08/30 15:45:54 alibrary
+Adding geant4vmc support
+
+Revision 1.35.10.1 2002/06/10 17:51:15 hristov
+Merged with v3-08-02
+
+Revision 1.35 2001/05/30 16:15:47 fca
+Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova
+
+Revision 1.34 2001/05/30 15:55:35 hristov
+Strings compared instead of pointers
+
+Revision 1.33 2001/05/30 14:04:31 hristov
+Dynamic cast replaced (F.Carminati)
+
+Revision 1.32 2001/03/23 00:12:23 nilsen
+Set Reading of AliITSgeom data from Geant3 common blocks as the default and
+not a .det file. Removed redundent calls to BuildGeometry.
+
+Revision 1.31 2001/02/13 16:53:35 nilsen
+Fixed a but when trying to use GEANT4. Needed to replace
+if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
+because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
+did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
+to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
+in the same way as in AliITSv5.cxx.
+
+Revision 1.30 2001/02/09 20:06:26 nilsen
+Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
+
+Revision 1.29 2001/02/09 00:05:31 nilsen
+Added fMajor/MinorVersion variables and made other changes to better make
+use of the new code changes in AliITSgeom related classes.
+
+Revision 1.28 2001/02/02 23:57:28 nilsen
+Added include file that are no londer included in AliITSgeom.h
+
+Revision 1.27 2001/01/30 09:23:13 hristov
+Streamers removed (R.Brun)
+
+Revision 1.26 2000/11/30 11:13:11 barbera
+ Added changes suggested by Federico Carminati on nov, 30, 2000
+
+Revision 1.25 2000/10/05 20:50:00 nilsen
+Now using root generated streamers.

+fix for bug with HP and Sun unix + fix for event display in ITS-working branch
+
+Revision 1.14.4.3 2000/03/04 23:46:38 nilsen
+Fixed up the comments/documentation.
+
+Revision 1.14.4.2 2000/03/02 21:53:02 nilsen
+To make it compatable with the changes in AliRun/AliModule.
+
+Revision 1.14.4.1 2000/01/12 19:03:33 nilsen
+This is the version of the files after the merging done in December 1999.
