3// Root macro that opens a mini GUI for running aliroot with Geant4.
4//
5// To run aliroot with Geant4 using the g4menu.C:
6// aliroot
7// root [0] .x g4menu.C
8// --> Select "Init" and then "Run" button
9//
10// The the bar enables to start Geant4 interactive session:
11// --> Select "Geant4UI" button and use Geant4 interactive commands;
12// In case TGeant4 has not yet been created you need first
13// select "Geant4" button before selecting "Geant4UI".
14// To go back to Root UI, type exit.
