Ie, you build foo-1.0-2 in the side tag against your new library, take a week rebuilding things and finally you are ready to tag those builds back in, but in the mean time the maintainer build foo-1.0-3 to fix something. Now you need to rebuild it again. So, a side tag is a thing you think you can get done pretty quickly, imho. kevin
