23 GNU gperf is a perfect hash function generator. For a given
24 list of strings, it produces a hash function and hash table, in
25 form of C or C++ code, for looking up a value depending on the
26 input string. The hash function is perfect, which means that
27 the hash table has no collisions, and the hash table lookup
28 needs a single string comparison only.
29
30 GNU gperf is highly customizable. There are options for
31 generating C or C++ code, for emitting switch statements or
32 nested ifs instead of a hash table, and for tuning the algorithm
33 employed by gperf.
