Can you place build configurations under version control?

Is there a way to place your build chain and build configurations under version control so you can go back to a prior version of your product and rebuild it exactly the same way?

This is a very similar question to what is posted on stackoverflow here (http://stackoverflow.com/questions/3136165/how-does-one-version-control-the-configuration-of-a-teamcity-project)

Thanks.
