          <para> The Simplify filter is used to simplify routes and
          tracks for use with formats that limit the number of points
-         they can contain.  The filter takes one required parameter,
-         which is the maximum number of points a route may contain.
-         It attempts to remove points from each route until the number
-         of points is at or below the given maximum, while also
-         attempting to preserve the shape of the original route as

+         <para>You must specify either the "count" option or the "error" option.
+         The count option requires a number, which is the maximum number
+         of points that will appear in the simplified track.  The error 
+         option takes a distance, optionally followed by an 'm' for miles or
+         a 'k' for kilometers.  That distance specifies the maximum error;
+         how that error is determined depends on the simplification method,
+         described next.</para>
+         <para>You may also specify the method by which the filter chooses
+         which points to remove.  The options are "length", which tries to
+         remove points that have the smallest effect on the overall length
+         of the route, or "crosstrack", which tries to remove points that 
+         have the smallest overall effect on the shape of the route.  The
