+"""Find the maximum recursion limit that prevents interpreter termination.
+
+This script finds the maximum safe recursion limit on a particular
+platform.  If you need to change the recursion limit on your system,
+this script will tell you a safe upper bound.  To use the new limit,
+call sys.setrecursionlimit().
+
+This module implements several ways to create infinite recursion in
+Python.  Different implementations end up pushing different numbers of
+C stack frames, depending on how many calls through Python's abstract
+C API occur.
+
+After each round of tests, it prints a message:
+"Limit of NNNN is fine".
+
+The highest printed value of "NNNN" is therefore the highest potentially
+safe limit for your system (which depends on the OS, architecture, but also
+the compilation flags). Please note that it is practically impossible to
+test all possible recursion paths in the interpreter, so the results of
+this test should not be trusted blindly -- although they give a good hint
+of which values are reasonable.
+
+NOTE: When the C stack space allocated by your system is exceeded due
+to excessive recursion, exact behaviour depends on the platform, although
+the interpreter will always fail in a likely brutal way: either a
+segmentation fault, a MemoryError, or just a silent abort.
+
+NB: A program that does not use __methods__ can set a higher limit.
