"""Bootstrap setuptools installation

​

If you want to use setuptools in your package's setup.py, just include this

file in the same directory with it, and add this to the top of your setup.py::

​

    from ez_setup import use_setuptools

    use_setuptools()

​

If you want to require a specific version of setuptools, set a download

mirror, or use an alternate download directory, you can do so by supplying

the appropriate options to ``use_setuptools()``.

​

This file can also be run as a script to install or upgrade setuptools.
