MATH-ORIENTED SCHEME CODE
                                       
   These are some math-oriented Scheme programs.
   
     * This code, due to Jim Miller, has something to do with lattices,
       but I really do not understand it. It is a heavy-duty
       grind-and-roll for most scheme interpreters (conform.scm).
     * The Jacal system, a symbolic mathematics system which runs under
       Scheme, by Aubrey Jaffer (jacal1a5.tar.gz)
     * R. Kent Dybvig's four different fib routines using peano
       arithmetic, regular, cps, global-value and call/cc (mixfib.scm).
     * An implementation of the Sutherland-Hodgmann polygon clipping
       algorithm for "T", by Olin Shivers (polyclip.scm).
     * A prime number calculation program (primes.scm), by Ozan Yigit.
     * Chez version of Scott E. Fahlman's "QuickProp", a variation on
       back-propagation, courtesy Song Koh (qprop.scm).
     * A minimal standard random number generator for 32-bit integers
       (rand.scm). Taken from CACM 31(10), oct 88. By Ozan Yigit.
