deployment

Fabric has become my deployment tool of choice both for deploying Django projects and for initially configuring Ubuntu slices. However, my current workflow with Fabric isn't very DRY, as I find myself:

copying the fabfile.py from one Django project to another and
modifying the fabfile.py as needed for each project (e.g., changing the webserver_restart task from Apache to Nginx, configuring the host and SSH port, etc.).

One advantage of this workflow is that the fabfile.py becomes part of my Git repository, so between the fabfile.py and the pip requirements.txt, I have a recreateable virtualenv and deployment process. I want to keep this advantage, while becoming more DRY. It seems that I could improve my workflow by:

being able to pip install the common tasks defined in the fabfile.py and
having a fab_config file containing the host configuration information for each project and overriding any tasks as needed

Any recommendations on how to increase the DRYness of my Fabric workflow?
