     (description
-     "GNU gperf is a perfect hash function generator.  For a given
-list of strings, it produces a hash function and hash table, in
-form of C or C++ code, for looking up a value depending on the
-input string.  The hash function is perfect, which means that
-the hash table has no collisions, and the hash table lookup
-needs a single string comparison only.
-
-GNU gperf is highly customizable.  There are options for
-generating C or C++ code, for emitting switch statements or
-nested ifs instead of a hash table, and for tuning the algorithm
-employed by gperf.")
