Please add a generic FAQ section to README.txt and clarify the following things:
1) Why do you need to write yet another packaging framework? 2) You're a Distutils's maintainer. Why don't you add these features to Distutils? 3) Any plan to add uninstall command?
The answer of the first question would be: http://tarekziade.wordpress.com/2008/09/24/distribute-a-setuptools-fork/
