[Xastir] One more detail on the 2008 Tiger/Line maps

I almost forgot on important detail that Craig, N6YXK, showed me to  
allow proper layering so polygon fills don't clobber roads, etc.

Quoting Craig:

==================================================
   I have the six western states of the Tiger/Line 2007 files loaded on
   my laptop; this makes for a *lot* of files to set level numbers  
on.  So,
   when you have this many of the Tiger map files, the easiest way to
   change some of the Tiger maps to have different layers is to use "vi"
   on the map_index.sys file while xastir is not running.  Once you are
   editing the file, use the following 3 commands in "vi" to change the
   layers.
   This assumes that, like with my xastir, new maps get added into the
   list at layer 1000.

   :g/tabblock/s/01000/00995/
   :g/pointlm/s/01000/00996/
   :g/arealm/s/01000/00997/

   (translation: global search throughout the file for lines with  
"arealm"
   and substitute on that line for "01000", a "00997")

   This moves the tabblock (& tabblock00) files, pointlm files, and
   arealm files down underneath the roads maps.  Otherwise the roads
   can get covered up by urban background coloring.  Or you can do
   this through the GUI interface as well.
==================================================

Below is an example of a portion of my map_index.sys file, primarily  
for Brown county in Texas:

As far as the dbfawk scripts go, I sent Curt the scripts zipped up.   
He can disseminate as he sees fit.

Many thanks to Craig for sharing his dbfawk scripts with me.
