// Revision 1.4  2000/05/09 20:15:43  kathy
// transfer obsolete macros to /macros/obsolete;  update other macros so that they use standard default inputs plus only few events by default so they'll be easy to run in autoQA macro testing
//
// Revision 1.3  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 1.2  2000/01/10 21:49:07  kathy
// put owner statement in macros
//
// Revision 1.1  1999/11/09 19:10:47  calderon
// Initial Commit
// Example macro to read .trs file.
// owner: Manuel Calderon
//
// Description:
// Read in a .trs file created with TrsWrite.C
