+    (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.
+
+GNU gperf is highly customizable.  There are options for
+generating C or C++ code, for emitting switch statements or
+nested ifs instead of a hash table, and for tuning the algorithm
+employed by gperf.")
