# This dbfawk file is used to map arbitrary dbf data that accompanies
# a shapefile into Xastir canoncical values of:
# key - search key
# lanes - width of feature (usually a road but applies to rivers, etc. too)
# color - color to draw the road
# name - name of the road for labels
# filled - whether a polygon is drawn filled or not
# fill_color - color to fill polygon with
# pattern - line pattern for road, river, etc. (0 - solid; 1 - dash; 2 - double dash)
# display_level - highest zoom level at which to display the feature
# label_level - highest zoom level at which to display the label
# symbol - 3 char 'TIO': table, ID, overlay
# NOTE: This file format is modeled after awk but is nowhere near awk
# compatible.
#
# This file is used to map USGS 24k grid shapefiles, which contains bounding
# rectangles for USGS 1:24000 quadrangles.
# The shapefile itself can be had from

# BEGIN is called once per dbf file which contains multiple records.
BEGIN {
# dbfinfo is the "signature" of the dbf file listing the column names in order.
# dbfinfo should match the dbf file that we say this dbfawk file goes with.

# dbffields is which of the above fields we actually want to look at.
# No point reading dbffields that are not looked at further.

# BEGIN_RECORD is called once per dbf record which contains multiple fields.
# Use this rule to re-initialize variables between records.
# use color 11 to highlight stuff that isn't properly mapped.
