| """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. |
