/**
 * @file sim-hlt-rawddl.C
 * @brief Publishing of RAW DDL data into the HLTOUT.
 *
 * Example macro to produce ddl raw data blocks in the HLTOUT. The HLT
 * chain is run embedded into AliRoot simulation. 
 *
 * The example publishes the ITSSDD data into the HLTOUT according to
 * the configuration in the conf-hlt-rawddl.C macro. The normal digit
 * to raw conversion is used to have the raw data available.
 * \b Note: if you want to change this example for another detector,
 * you need to change the detector in both this macro and the
 * configuration.
 *
 * Usage: aliroot -b -q sim-hlt-rawddl.C | tee sim-hlt-rawddl.log
 *
 * The chain to be run is defined by the macro given to the parameter
 * 'config='
 *
 * The macro assumes the data to be already simulated. If it should run
 * within the initial simulation, comment the corresponding functions
 * below (SetRunGeneration etc.)
