Is there any way to get a machine-readable alert when a new file is added to a github repo? I found a way to see an atom feed of commits, but the feed doesn't include any breakdown of activity (files added, changed, etc).

The eventual goal would be to send a tweet when a file is added for the first time. Ideally the method would be something simple I could use with, say, <http://ifttt.com>.

The repo in question is not my own, btw.
