I've used José's patch as a starting point to setup RSS and ATOM feeds
for the buildbot for the Subversion project. For our purposes I had to
make a lot of changes:

- supports both RSS 2.0 and ATOM 1.0 (minimal support though, will be
reviewed soon)
- instead of showing the result of the last build for each builder, this
code feeds not only the last, but all FAILed builds, whatever the
builder. Currently nr. of entries is limited to 25.
- each feed entry contains:
  .) timestamp of the build, branch, svn revision and buildername.
  .) a link to the build information page
  .) author of the change
  .) name of the failed step
  .) last 30 lines of the log of the last (normally also failed) step
- this is not a patch to the buildbot code, but a completely separate
implementation, no modifications to the bb code are needed. I like this
approach better, it makes it easier to keep in sync with buildbot releases.
- the code is reorganized a bit to better support the two output formats
rss and atom.

Example configuration:

The latest version of the code can be found here:

Obviously the code can be improved in a lot of places, it's the first
version after all. Hope someone can put it to good use, feel free to use
it. Feedback appreciated.
