Single-line setuptools install
For those of you just starting out with setuptools, here's a quick way to install it. After running this, you'll have access to easy_install for all of your other installation needs:
python -c "import urllib; urllib.main()" \ http://peak.telecommunity.com/dist/ez_setup.py \ | python - -U setuptools
Note that this will execute Python code from a remote host without any kind of authenticity check. Use at your own risk. Only tested on Mac OS X, FreeBSD, and Linux (with Python 2.3 and 2.4).
