+The SparseHash library contains several hash-map implementations,
+including implementations that optimize for space or speed.
+
+These hashtable implementations are similar in API to SGI's hash_map
+class and the tr1 unordered_map class, but with different performance
+characteristics. It's easy to replace hash_map or unordered_map by
+sparse_hash_map or dense_hash_map in C++ code.
+
+They also contain code to serialize and unserialize from disk.
