+ (description
+ "This package provides an R wrapper for libnabo, an exact or approximate
+k nearest neighbour library which is optimised for low dimensional
+spaces (e.g. 3D). @code{nabor} includes a @code{knn} function that is
+designed as a drop-in replacement for the RANN function @code{nn2}. In
+addition, objects which include the k-d tree search structure can be returned
+to speed up repeated queries of the same set of target points.")
