43 r.grow adds cells around the perimeters of all areas in a user-speciā
44 fied raster map layer and stores the output in a new raster map layer.
45 The user can use it to grow by one or more than one cell, or like
46 r.buffer, but with the option of preserving the original cells (similar
47 to combining r.buffer and r.patch).
