  40 DESCRIPTION
  41 -----------
  42
  43
  44 These functions generate hash values from a key using a variety of
  45 algorithms. These functions can be used standalone, or as arguments
  46 to hashkit_set_hash_fn(3) or hashkit_set_continuum_hash_fn(3).
  47
  48 The hashkit_hsieh() is only available if the library is built with
  49 the appropriate flag enabled.
