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