// Example macro to use the BFC trigger filter maker.
// Takes as input fzd file, then processes EMC response.
// If event fires selected bits from EMC layer 2 DSM
// (which corresponds to selecting triggers), then
// BFC reconstruction continues. Otherwise, event
// is skipped. Substantial savings in processing
// time and disk space can be achieved when
// reconstruction of complex detectors like the
// TPC is skipped for uninteresting events.
