Re: TGeant3 geant321 version number

Hello,

    we have several improvements (at least we do hope so) that we never ported back into the official 321 of the cern library. There was a synchronisation some time (2 years) ago, but then we diverged again. The file gversc.inc may not be meaningful any more, thanks for pointing this out. We might resynchronise, however when you say that there are differences, how can you be sure that these are due to the transport and not to the geometry? This is indeed the most likely cause.
