-    (description
-     "This library contains several hash-map implementations, similar in API
-to SGI's @code{hash_map} class, but with different performance
-characteristics.  @code{sparse_hash_map} uses very little space overhead, 1-2
-bits per entry.  @code{dense_hash_map} is very fast, particulary on lookup.
-@code{sparse_hash_set} and @code{dense_hash_set} are the set versions of these
-routines.  All these implementation use a hashtable with internal quadratic
-probing.  This method is space-efficient -- there is no pointer overhead --
-and time-efficient for good hash functions.")
