"""A fake shutil module implementation that uses fake_filesystem for
unit tests.
Note that only `shutildisk_usage()` is faked, the rest of the functions shall
work fine with the fake file system if `os`/`os.path` are patched.

:Includes:
  FakeShutil: Uses a FakeFilesystem to provide a fake replacement for the
    shutil module.

:Usage:
  The fake implementation is automatically involved if using
  `fake_filesystem_unittest.TestCase`, pytest fs fixture,
  or directly `Patcher`.
