+define Package/gperf/description
+ GNU gperf is a perfect hash function generator. For a given list of strings, it
+ produces a hash function and hash table, in form of C or C++ code, for looking 
+ up a value depending on the input string. The hash function is perfect, which 
+ means that the hash table has no collisions, and the hash table lookup needs a
+ single string comparison only.
