-# Description:   d.rast.leg clears the entire screen, divides it into a main
-#                (left) and a minor (right) frames, and then display a raster 
-#                map in the main frame and the map legend in the minor frame.
-#                The user can run the program interactively or 
-#                non-interactively.
