(csilvers) Fri Jan 14 16:53:32 2005 Google Inc. * sparsehash: initial release: The sparsehash package contains several hash-map implementations, similar in API to SGI's hash_map class, but with different performance characteristics. sparse_hash_map uses very little space overhead: 1-2 bits per entry. dense_hash_map is typically faster than the default SGI STL implementation. This package also includes hash-set analogues of these classes.
