+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.
+
+FLANN is written in C++ and contains bindings for the following languages: C,
+MATLAB and Python.
