Software to automatically update ratings

Hi all,

We use a piece of software called Tornelo to run and rate our rapid events at the moment. We don't rate them with our national federation or FIDE at the moment because compared with using this software it's much more work for the volunteers who run the club. 

I was wondering if anyone knows of any other software which automatically updates ratings based on results in an event?

SwissSys seems to be wildly used. But I don't know if it will work for you.

Other options may include: Swiss-Manager, Swiss Perfect (paid), or JavaPairing, Chess Tournament Management (free, sourceforge).

Thanks for your reply lesperance, i'll check them out.

Just to clarify, we're not looking for something that will upload results to a FIDE server. Just a system that will apply a rating change formula internally based on the results of an event.
