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