-"""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.
