Incremental dump of a mysql database

I've just written a couple of simple ruby classes to help dump a mysql database without locking tables for extended periods.

In particular, some of my tables contain lots of date-based data which is not changed after the day it was created. The classes can be told to dump such data one day at a time, and won't dump a day that has already been dumped.

Check it out on github;

I hope people find it useful.
