| 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. | |
