I'm following herokus getting-started guide for Django.
I've set-uped and sourced an virtual env:
virtualenv venv --distribute
source venv/bin/activate
after this I try to install a few things:
pip install Django psycopg2 dj-database-url
I create a project and pip freeze the requirements. At this point I get two extra requirements:
Django==1.4.1
distribute==0.6.28
dj-database-url==0.2.1
psycopg2==2.4.5
wsgiref==0.1.2
Where did they come from?
