/**
 * \file
 *
 * Auxiliary program to blend and write summary data.
 *
 * This application can be used to convert measured rates of any detector 
 * to a consistent set of rates for a simulated complete detector.\n
 * The rates as well as the high-rate veto and FIFO (almost) full will then be included 
 * in the run-by-run simulations using JTriggerEfficiency.cc.
 *
 * The option <tt>-f <inputFile></tt> corresponds to a list of input files 
 * containing summary data (commonly referred to as "measured rates").\n
 * These data can originate from any detector.
 *
 * The option <tt>-a <detectorFile></tt> corresponds to the detector to be used in simulations.\n
 * This could be a complete detector.
 *
 * The option <tt>-@ <parameters></tt> corresponds to the trigger parameters.\n
 * This is needed here because in the run-by-run simulations,
 * the trigger parameters are taken from the input file.
 *
 * The application JSummaryWriter.cc can be used to write summary data according user defined input rates.
