7 Branches So far, all revisions shown in this manual have been on the main trunk of the revision tree, i.e., all revision numbers have been of the form x . y . One useful feature, especially when maintaining several releases of a software product at once, is the ability to make branches on the revision tree. Tags , symbolic names for revisions, will also be introduced in this chapter. The revision numbers live a life of their own. They need not have anything at all to do with the release numbers of your software product.
