     =========================================================

                            TestEm0
                            -------

  This program is not a simulation. It prints the cross sections and stopping
  power used by the standard electromagnetic package, via G4EmCalculator
  which extracts these data from the PhysicsTables.
	
  The program can be used in batch or interactively.	
 
  - compile and link to generate an executable
	% cd geant4/examples/extended/electromagnetic/TestEm0
	% gmake
 		
  - execute TestEm0 in 'batch' mode from macro files :
	% TestEm0   TestEm1.in
 		
  - Interactively, a typical sequence will be :
	% TestEm0
	....
	Idle> /testem/det/setMat Silicon
	Idle> /testem/phys/setCuts 100 um	
 	Idle> /gun/particle e-
        Idle> /gun/energy 10 MeV
        Idle> /run/beamOn
	 
  The last command triggers BuildPhysicsTable() and executes the program.
  
   
                            DirectAccess
                            ------------
			    
  DirectAccess is a small batch program which shows how to compute the same
  basic data directly from the processes (indeed the models).
  
  To run it, change name in the first line on GNUmakefile before to compile.
