-# @(#) krand  Produces a random number within integer limits
-# "krand" Korn shell script generates a random number in a
-# specified range with an optionally specified ``seed'' value.
-# Author: Peter Turnbull, May 1993
-# Modified by: Becca Thomas, January 1994

-# changed the optional third argument to a -s option, converted to
-# bash v2 syntax -- chet@po.cwru.edu
