+ (description
+ "This package provides an R port of the library Clipper. It performs
+polygon clipping operations (intersection, union, set minus, set difference)
+for polygonal regions of arbitrary complexity, including holes. It computes
+offset polygons (spatial buffer zones, morphological dilations, Minkowski
+dilations) for polygonal regions and polygonal lines. It computes the
+Minkowski Sum of general polygons. There is a function for removing
+self-intersections from polygon data.")
