# The configuration of this very script is perfomed via shell variables.
# Here the list of parameters is reported
#
# DM_EXE_DIR  -> the absolute path of the folder which contain DetectorControl.exe
# DM_DATA_DIR -> the absolute path of the folder which contain the detectorfile
# PC_CONF_DIR -> the absolute path of the pc.cfg configuration file
# DAQ_SERVER  -> IP address of the DAQ Server
# DAQ_USER    -> user name on the DAQ Server
