   @ after this step an application library $(PAM_VMC)/lib/tgt_$(PLATFORM)/libPamVMC_fc.so will be compiled
     and some calibration files will be copied from $(PAM_VMC)/aux@

+/////////////EXTERNAL DIGITIZER/////////////////
+In aux/PamVMVDigitizer you can find a source code of stand-alone digitizer. Just do make. 
+There are only 3 parameters: input root-file name, output raw-filename and integer random seed.
+If you specify 0, then TRandom3(0) object will be created. All digitizers use this object.
+Please note, that current version of digidaizer could be not compatible with root-files generated
+with previous versions of PamVMC due to addtitonal variables in PamVMCDetectorHit class

 /////////////SPGECTRA GENERATOR/////////////////
 @ spectra_generator is a tool which allow you to generate tracks above the apparatus 
   isotropically and save initial kinematic parameters (X0,Y0,Z0=110., P, Theta, Phi)
