#  This AWK script takes an EMME/2 or STAN network file (d211.in)
#  and generates an annotation file containing only the centroid numbers
#  or labels.
#
#  usage:  gawk -f cent2ann.awk [COL=index] [SIZE=size] [LAB=1] d211.in > annotx
#
#  Default:color=1
#          size =4 (hardware unit)
#          label=0 (centroid number)
