My understanding is that a tag is just a convenient way to cluster a
set of file versions so they can be checked out together. In practice,
it's usually synonymous with using a particular -D date flag.
A branch, on the other hand, allows the dreaded double patching - the
branch can now evolve independently of the trunk, perhaps to be merged
later, perhaps not. If you double patch, no need to merge, just abandon
the branch when it gets too different.

CVS in a branching environment)
