 The GRASS program <em>r.patch</em> allows the user to build a new
 raster map the size and resolution of the current region by assigning
 known data values from input raster maps to the cells in this region.
-This is done by filling in "no data" cells, those that do not yet
-contain data, contain NULL data, or, optionally contain 0 data,
-with the data from the first input map.
+<br>
+In case of overlapping input raster maps this is done by filling in
+"no data" cells, those that do not yet contain data, contain NULL data,
+or, optionally contain 0 data, with the data from the first input map.
 Once this is done the remaining holes are filled in by the next input map,
 and so on.
+<br>
+In case of adjacent input raster maps the output map contains the map
+mosaic.
 
 <p>
-This program
-is useful for making a composite raster map layer from two or more adjacent
-map layers, for filling in "holes" in a raster map layer's data (e.g., in
-digital elevation data), or for updating an older map layer with more recent
-data. The current geographic region definition and mask settings are
-respected.
+Hence this command is useful for
+<ul>
+<li> making a composite raster map layer from two or more adjacent map layers,</li>
+<li> for filling in "holes" in a raster map layer's data (e.g., in digital
+     elevation data), or
