"""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.
