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