+     "This package implements exact and approximate methods for nearest
+neighbor detection, in a framework that allows them to be easily switched
+within Bioconductor packages or workflows.  The exact algorithm is implemented
+using pre-clustering with the k-means algorithm.  Functions are also provided
+to search for all neighbors within a given distance.  Parallelization is
+achieved for all methods using the BiocParallel framework.")
