Working with VirtualEnv and Pip

I've just begun working with VirtualEnv and Pip for my Python project package management. So far I'm impressed. Rather than just rehash the tutorials I've read I'll just point you to some good ones...

Okay, here's a few commands I've used...

virtualenv --no-site-packages env

pip install -E env yolk

source env/bin/activate

yolk -l

pip install -E env -e svn+http://code.djangoproject.com/svn/django/trunk/

pip freeze -E env > requirements.txt

pip install -E env -r requirements.txt
