-"""Bootstrap distribute 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 distribute_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.
