%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.
