         Abstract:

         This program solves cryptic addition problems by a  brute-force
         depth-first  search.  In its current incarnation it will handle
         problems of up to 10 addends of up to 60 digits each.  The user
         is  prompted  for  number  of addends, verification (useful for
         large problems) whether or not all solutions are  desired,  and
         whether  a  trace  of  the  logic  is desired.  Then the actual
         addends and sum are requested (with a verify pass if  desired).
         Input is case-sensitive.
