simulation     : sim.C
digitization   : digi.C
hit finder     : hit.C
reconstruction : reco.C
event display  : eventDisplay.C

Reconstruction requires valid Look-Up Table (different for different DIRC geometries). 
in lut/ folder:
LUT simulation : simLut.C
LUT creation   : fillLut.C


Example of simulation:

root -q sim.C && root -q digi.C && root -q hit.C && root eventDisplay.C
