+"PYSTONE" Benchmark Program
+
+Version: Python/1.1 (corresponds to C/1.1 plus 2 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.
