Working Google Sites Backup Tool

Google finally has provided a decent tool for backing up Google Sites.

It is a demo java application available from Google Code. This tool has been available for a little while now, but it did not work the last time I tried it. I downloaded it last night and tried it out this morning and am happy to say that it works great.
You can get the tool and documentation at http://code.google.com/p/google-sites-liberation/.
