I was a little confused by setuptool's explanation of how to make an egg installable as
easy_install yourproject==dev
How do you tell it where your repository is? You actually have to put a URL somewhere for setuptools to find. I.E. In the long_description, the body of the page that your url loads, or perhaps elsewhere that looks like this:
http://svn.yourproject.com/trunk#egg=yourproject-dev
In other words, a URL to the repository containing a fragment in the correct format.
