// $Log: TrsWrite.C,v $
// Revision 1.6  2006/08/15 21:43:06  jeromel
// Fix rhic -> rhic.bnl.gov
//
// Revision 1.5  2000/01/25 16:06:37  fisyak
// g2r -> g2t
//
// Revision 1.4  2000/01/20 18:18:16  calderon
// fixed for current TRS in dev.  Current DB in dev is ROOT DB, because
// Electronics DB from MySQL is not accessible.  When it is, just comment out
// ROOT DB part and uncomment MySQL DB part.
//
// Revision 1.3  2000/01/10 21:49:07  kathy
// put owner statement in macros
//
// Revision 1.2  1999/11/16 22:31:02  calderon
// Version using ROOT Database (Hopefully soon we'll switch to
// the TPC Db).
//
// Revision 1.1  1999/11/09 19:12:04  calderon
// Initial Commit.
// Example to write a .trs file from a muon processed through TRS.
