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