// $Id$
//
// Root macro that opens a mini GUI for running aliroot with Geant4.
//      
//  To run aliroot with Geant4 using the g4menu.C:
//  aliroot
//  root [0] .x g4menu.C
//  --> First select "Geometry" to build geometry.root file
//  --> Then re-run aliroot and select "Run" button
//	    
// The Init button is kept for debugging purposes,
// it itializes MonteCarlo but it does not itialize
// completely ALICE framework. That's why to run simulation,
// you have to re-run aliroot and select Run button.
//
// The menu enables to start Geant4 interactive session:
//  --> Select "Geant4UI" button and use Geant4 interactive commands;
// To go back to Root UI, type exit.
//
