(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.")
