+class RBiocneighbors(RPackage):
+    """Nearest Neighbor Detection for Bioconductor Packages.
+
+       Implements exact and approximate methods for nearest neighbor detection,
+       in a framework that allows them to be easily switched within
+       Bioconductor packages or workflows. Exact searches can be performed
+       using the k-means for k-nearest neighbors algorithm or with vantage
+       point trees. Approximate searches can be performed using the Annoy or
+       HNSW libraries. Searching on either Euclidean or Manhattan distances is
+       supported. Parallelization is achieved for all methods by using
+       BiocParallel. Functions are also provided to search for all neighbors
+       within a given distance."""
