    I'll tag the BRAT version next time. It's just when I receive messages
    from smbd, about some major changes, I always checkout a fresh version
    (or update, if no new classes/files were introduced), deleting the old
    one. I thought everybody else are doing the same...

      There're two major changes in BrCalibrBB.dat : 
    	1. Old values are refined and retuned, based on runs 2484 and 2235
    	2. Individual values for ADC gaps starting point and width are
    added            for Big tubes.

      Yes, all calibration process will go wrong if one uses old version of
    BrCalibrBB.dat. That's why one should update his/her BRAT. In general, I
    guess, it'll be fixed by making database stuff to work for everybody.
