 <em>r.basin</em> generates the main morphometric parameters of the 
 basin starting from the digital elevation model and the coordinates 
-of the basin's closing section. 
+of the basin's closing section (outlet). 
 
 <h3>Important:</h3>
 
 The closing section's coordinates must belong to the river network 
 generated by <a href="r.stream.extract.html">r.stream.extract</a>. 
 It is suggested to run it beforehand.
+In G7, r.basin has been improved to take in input coordinates not 
+exactly belonging to the river network (but not too far from it). 
+It basically snaps to the closest point belonging to the network. 
+This feature is experimental and might not produce the expected result. 
+To check if the snapped outlet is acceptable, at the end of the 
+computation, two outlet vector maps are produced: the one with the 
+coordinates inserted by the user and the snapped one. If the user is 
+not happy with this latter, should tweak the coordinates to match with 
+the river network.
