 Description
     This velocity inlet/outlet boundary condition is applied to pressure
-    boundaries where the pressure is specified.  A zero-gradient condtion is
+    boundaries where the pressure is specified.  A zero-gradient condition is
     applied for outflow (as defined by the flux); for inflow, the velocity is
     obtained from the patch-face normal component of the internal-cell value.

 Description
     Class to calculate the cell-addressing between two overlapping meshes
 
-    Three methods are currently available:
+    Mapping is performed using a run-time selectable interpolation mothod
-    - direct           : 1-to-1 mapping between meshes
-    - mapNearest       : assign nearest cell values without interpolation
-    - cellVolumeWeight : volume consistent mapping
-
-    The \c direct and \c cellVolumeWeight options are volume conservative,
-    whereas mapNearest is non-conservative.
