Nope. PVCS had (has?) both "labels" and "tags". We'd tag something as a
given release, and you exported by tag to get the full release as of that
date. You wouldn't put the tag on until everything had been promoted, and
the system locked, then gang tag everything that was, say, labeled
"production".
