 input event file: (e.g. events.lhe)
  input is events.lhe                    

 name for output file: (e.g. dec-events.lhe)
  output is dec-events.lhe                

  Input particle to be decayed (e.g. t~):
  particle is ta-                           

 1   ta- -> vt   e- ve~           
 2   ta- -> vt  mu- vm~           
 3   ta- -> vt   l- vl~ (e+mu)    
 4   ta- -> vt   pi-              
 5   ta- -> vt  rho(770)-
