+SUMMARY="A library for efficient similarity search and clustering of dense vectors"
+DESCRIPTION="Faiss is a library for efficient similarity search and clustering of dense vectors. \
+It contains algorithms that search in sets of vectors of any size, up to ones that possibly do \
+not fit in RAM. It also contains supporting code for evaluation and parameter tuning. Faiss is \
+written in C++ with complete wrappers for Python/numpy. Some of the most useful algorithms are \
+implemented on the GPU. It is developed primarily at Meta's Fundamental AI Research \
+*https://ai.facebook.com/* group."
