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