+<h2>DESCRIPTION</h2>
+
+Module <em>r.stream.basins</em> is prepared to delineate basins and subbasins with
+different input data. Module is prepared to delineate unrestricted number of
+basins in one step. It can delineate basins with three methods:
+<ul>
+<li>Using coordinates: this option simply copies functionality of <a
+href="r.water.outlet.html">r.water.outlet</a>.
+<li>Using vector points: it allow to manually point outlets with any method
+<li>Using streams (most advanced) it allow on lots of modifications. See
+examples for more details.
+</ul>
+Only one method can be used at once. Methods cannot be mixed.
+<p>
+The most recommended method requires two maps: direction and streams. In spite of
+stream map we can store information required to proper delineation, we can
+also enumerate stream categories for which basins are to be created (cats
+option). Module is prepared to work with output data of <em>r.watershed,
+r.stream.extract, r.stream.order</em> also with modification done by
+<em>r.reclass</em> and <em>r.mapcalc</em>. r.stream.basin can delineate basins
+according outlets marked by raster streams, and polygons, vector points and
+numerical coordinates. If outlets are marked by points or coordinates it
+delineates basins which cells contribute to that points, if outlets are marked by
+streams it delineate cells which contribute to the last (downstream) cell of the
+every stream. If outlets are marked by polygon it delineate cells contributing
+to most downstream cell of the polygon. If polygon covers more outlets than of
+one basins it will create collective basin for all outlets  with common
+category.
