#
# Input:  SNAP file created with DRUDG from the schedule for your station
#
# Output: The 'recexpt_[stationID]-tsunami' file for recording the experiment 
#         via real-time Tsunami client
#         You may need to edit 'recpass-tsunami' for correct server name and 
#          data rate settings.

# ---code could be improved a LOT.....----
