"""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. |
