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