2 """Bootstrap setuptools installation | |
3 | |
4 If you want to use setuptools in your package's setup.py, just include this | |
5 file in the same directory with it, and add this to the top of your setup.py:: | |
6 | |
7 from ez_setup import use_setuptools | |
8 use_setuptools() | |
9 | |
10 If you want to require a specific version of setuptools, set a download | |
11 mirror, or use an alternate download directory, you can do so by supplying | |
12 the appropriate options to ``use_setuptools()``. | |
13 | |
14 This file can also be run as a script to install or upgrade setuptools. | |
