       The  first form returns an array with the same elements as
       `arr', but quicksorted in ascending order according to the
       rules  in  `ob->fun()'.   `ob->fun()'  will  be passed two
       arguments for each call.  It should return -1,  0,  or  1,
       depending   on  the  relationship  of  the  two  arguments
       (lesser, equal to, greater than).

       Here are two common forms  for  the  compare  function  to
       take:

              int compare(string one, two) {
                  return strcmp(one, two);
              }

              int compare(int one, two) {
                  return (one - two);
              }

       The second form returns an array with the same elements as
       'arr', but quicksorted using built-in  sort  routines.   A
       'direction'  of  1 or 0 will quicksort in ascending order,
       while a 'direction' of -1  will  quicksort  in  descending
       order.  A limitation of the built-in sort routines is that
       the array must be homogeneous, composed entirely of a sin-
       gle type, where that type is string, int, or float.
