+	  FLANN is a library for performing fast approximate nearest
+	  neighbor searches in high dimensional spaces. It contains a
+	  collection of algorithms we found to work best for nearest
+	  neighbor search and a system for automatically choosing the
+	  best algorithm and optimum parameters depending on the
+	  dataset.
