This file should be used by G4 developers and category coordinators
to briefly summarize all major modifications introduced in the code
and keep track of all category-tags.2
It DOES NOT substitute the  CVS log-message one should put at every
committal in the CVS repository !

            Changed the name of the environment variable identifying
            the associated data library from G4PIXEDATA to G4PIIDATA
            as imposed by Geant4 spokesman M. Asai (apparently we are
            not allowed to use the word "PIXE", even if the code in
            this package simulates the physical phenomenon of PIXE)
