  41     (description
  42      "GNU gperf is a perfect hash function generator.  For a given
  43 list of strings, it produces a hash function and hash table, in
  44 form of C or C++ code, for looking up a value depending on the
  45 input string.  The hash function is perfect, which means that
  46 the hash table has no collisions, and the hash table lookup
  47 needs a single string comparison only.
  48
  49 GNU gperf is highly customizable.  There are options for
  50 generating C or C++ code, for emitting switch statements or
  51 nested ifs instead of a hash table, and for tuning the algorithm
  52 employed by gperf.")
