+<H2>DESCRIPTION</H2>
+
+This purpose of this module is to provide local environmental context to a
+series of vector points.
+<P>
+v.what.rast or r.what + coordinate alone may return a spike in the raster data
+without you knowing. What this script does is create a buffer around each
+vector point and gather some stats about the raster cells nearby and
+report them in a .csv table. Multiple raster maps can be sampled.
+It assumes the location is not lat/lon, and (in column names) that units
+will be meters. (r.buffer would be lat/lon safe; but I used r.circle
+because it allows starting from an exact coord not from the nearest cell)
+<P>
+v.rast.stats + v.buffer is problematic when input points' buffers overlap.
+<P>
+To speed up processing the working region is temporarily zoomed to a small
+area around each point. This will align the temporary region to the raster
+map's resolution and thus assumes that the raster map's region and resolution
+line up with each other.
