/**
 * \file
 * Auxiliary program to trigger Monte Carlo events.
 *
 * The options 
 *   - <tt>-a</tt> refers to the detector configuration that is used to convert Monte Carlo true information to raw data; and
 *   - <tt>-b</tt> refers to the detector configuration that is used to convert raw data to calibrated data.
 *
 * The event counter of the triggered events, as returned by KM3NETDAQ::JDAQEvent::getCounter(),
 * is set to the corresponding index of the Monte Carlo event in the output.\n
 * This allows for correlating the DAQ event to the Monte Carlo event.\n
 * The time of the DAQ hits can be correlated to the time of the Monte Carlo hits using the frame index 
 * and the time of the Monte Carlo event (Evt::mc_t), respectively (see also time_converter).\n
 * The universal time of the DAQ event is set to the universal time of the Monte Carlo event 
 * with a correction for the time of the event (read hits) within the time slice.\n
 * In run-by-run mode, the trigger parameters as well as the singles rates and status of the PMTs
 * are read from the given raw data file.\n
 * The two-fold (and higher) coincidence rates should still be provided on the command line.
