+<h2>NOTES</h2>
-The following is a sample <b>input</b> file to <EM>r.in.ascii</EM>:
+The geographic coordinates north, south, east, and west
+describe the outer edges of the geographic region. They
+run along the edges of the cells at the edge of the
+geographic region and <em>not</em> through the center of the cells
+at the edges.
