# This script generates the tabular bulletins for a single output points      #
# of  WAVEATCH MWW3 implemnatation. It is run as a child script by a          # 
# postprocessor.                                                              #

# Remarks :                                                                   #
# - The necessary files are retrieved by the mother script.                   #
# - Shell script variables controling time, directories etc. are set in the   #
#   mother script.                                                            #
# - This script runs in the work directory designated in the mother script.   #
#   Under this directory it geneates a work directory bull_$loc which is      #
#   removed if this script exits normally.                                    #
# - See section 0.c for variables that need to be set.                        #
# - This script replaces multiwavebull.sh and marks transition of generating  #
#   bulletins from the point output post processor instead of a separate      #
#   partitioning code                                                         #
