## Other Credits

- The backported `super()` and `range()` functions are derived from Ryan Kelly’s `magicsuper` module and Dan Crosta’s `xrange` module.

- The `futurize` and `pasteurize` scripts use `lib2to3`, `lib3to2`, and parts of Armin Ronacher’s `python-modernize` code.

- The `python_2_unicode_compatible` decorator is from Django. The `implements_iterator` and `with_metaclass` decorators are from Jinja2.

- The `exec_` function and some others in `future.utils` are from the `six` module by Benjamin Peterson.

- The `raise_` and `raise_with_traceback` functions were contributed by Jeff Tratner.

- A working version of `raise_from` was contributed by Varriount (GitHub).

- Documentation is generated with Sphinx using the `sphinx-bootstrap` theme.

- `past.translation` is inspired by and borrows some code from Sanjay Vinip’s `uprefix` module.
