-"PYSTONE" Benchmark Program
-
-Version:        Python/1.2 (corresponds to C/1.1 plus 3 Pystone fixes)
-
-Author:         Reinhold P. Weicker,  CACM Vol 27, No 10, 10/84 pg. 1013.
-
-                Translated from ADA to C by Rick Richardson.
-                Every method to preserve ADA-likeness has been used,
-                at the expense of C-ness.
-
-                Translated from C to Python by Guido van Rossum.
-
-Version History:
-
-                Version 1.1 corrects two bugs in version 1.0:
-
-                First, it leaked memory: in Proc1(), NextRecord ends
-                up having a pointer to itself.  I have corrected this
-                by zapping NextRecord.PtrComp at the end of Proc1().
-
-                Second, Proc3() used the operator != to compare a
-                record to None.  This is rather inefficient and not
-                true to the intention of the original benchmark (where
-                a pointer comparison to None is intended; the !=
-                operator attempts to find a method __cmp__ to do value
-                comparison of the record).  Version 1.1 runs 5-10
-                percent faster than version 1.0, so benchmark figures
-                of different versions can't be compared directly.
-
-                Version 1.2 changes the division to floor division.
-
-                Under Python 3 version 1.1 would use the normal division
-                operator, resulting in some of the operations mistakenly
-                yielding floats. Version 1.2 instead uses floor division
-                making the benchmark an integer benchmark again.
