+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, Python, and Ruby.
