// $Log: BrSelectGeantTracks.h,v $
// Revision 1.1.1.1  2001/06/21 14:55:07  hagel
// Initial revision of brat2
//
// Revision 1.3  2000/04/06 20:20:00  cholm

// 3. Moved checking of include definition to first line for easier reading
// 4. Put checks before all includes in the include files as per BRAT specifications
// 5. Added BrGeantHeader to Geant Makefile
// 6. All changes have been checked to compile on NT ala Cygnus
