    (description "The Generic Data Structures Library (GDSL) is a collection
of routines for generic data structures manipulation.  It is a re-entrant
library fully written from scratch in pure ANSI C.  It is designed to offer
for C programmers common data structures with powerful algorithms, and hidden
implementation.  Available structures are lists, queues, stacks, hash tables,
binary trees, binary search trees, red-black trees, 2D arrays, permutations
and heaps.")

    (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.")
