## Code Before:
from lib2to3.tests import test_fixers, test_pytree, test_util
import unittest
from test.test_support import run_unittest

def suite():
    tests = unittest.TestSuite()
    loader = unittest.TestLoader()

        tests.addTests(loader.loadTestsFromModule(m))
    return tests

def test_main():
    run_unittest(suite())


if __name__ == '__main__':
    test_main()

## Instruction:
Disable lib2to3 by default, unless run explicitly.
## Code After:

if __name__ != '__main__':
