+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. The Python bindings will need numpy, and the MATLAB
+bindings will need MATLAB installed and with its binaries directory set into
+the PATH. If you want to build the MATLAB bindings, set the environment
+variable WITH_MATLAB to 1.
