This format is derived from the <a class="link" href="fmt_xcsv.html" title="? Character Separated Values (xcsv)">xcsv</a>
format, so it has all of the same options as that format.
</p><p>
This format is used by GPSBabel itself as the input to the 
<a class="link" href="filter_arc.html" title="Include Only Points Within Distance of Arc (arc)">arc</a> and 
<a class="link" href="filter_polygon.html" title="Include Only Points Inside Polygon (polygon)">polygon</a> filters.  See those filters
for more information.
</p><p>
The arc format reads two numeric fields, a latitude and a longitude, 
in any format recognized as <a class="link" href="style_define.html#style_def_lathuman" title="LAT_HUMAN_READABLE">human 
readable</a> and writes as simple degrees decimal.  It really is
intended for GPSBabel's own internal use more than general use, though
it turns out to be a convenient way of expressing simple polylines and 
polygons.
