Brian Moon has posted a summary of how the whole development process is set up where he works (at Dealnews.com) all the way from version control out to deployment.

I was telling someone how we roll changes to production at dealnews and they seemed really amazed by it. I have never really thought it was that impressive. It just made sense. It has kind of happened organically here over the years. Anyhow, I thought I would share.

Some of the key technologies they use are things like Subversion for source code versioning, a script similar to svnmerge.py to do their merging for production, their staging server, makefiles for deployment and notifications sent out via XAMPP about how the build went and details on the release.
