5This program connects to the DAQ data source passed as argument
6and populates local "./result.txt" file with the ids of events received
7during the run.
8
9The program exits when being asked to shut down (daqDA_checkshutdown)
10or End of Run event.
11
12Messages on stdout are exported to DAQ log system.
