*nod*

I agree to almost everything of the rest. Just one question: What happens
if someone tags the whole repository, and then again, including the
previous tag of the whole repository, and so on, several times. I'm not
perfectly sure, but I believe you will get some explosive disc space usage
*on the client* when you check out the whole repository with some of these
whole-repo-tags. This will only happen with tags, because tags are copies.
(My kind of labels are not.) When I wrote that remark of mine was nonsense,
I thought you did wanted to use something other than tags for labelling.

Anyway, I think we dug out some great ideas, altogether. Especially these
server templates, I love that idea more and more. It will not cost any of
flexibility/freedom we have now, but the tools can learn about the repo-
structure. That's just - nice. :-)

Have fun
