3// Configuration macro for running aliroot with Geant4.
4// All AliRoot specifics are defined in g4ConfigCommon.C
5//
6// In order to run aliroot with Geant4, you have to Initialize
7// AliRun with this g4Config.C
8//
9// aliroot
10// root [0] gAlice->Init("g4Config.C");
11// root [1] gAlice->Run();
12//
13// You can also start from a mini GUI - g4menu.C.
14// See description in this macro.
