Here's the trick. In both of your examples, you don't tag the UCW
branch. You just "get" it. That means that the archive ('tla
tree-version')remains the one at common-lisp.net. If I want to put it in
my local archive, I need to tag it instead. When you do a get like that,
tla expects that you won't be wanting to edit it any time soon. There's
lots of little differences between a get and a tag, and a tag is the
recommended way to get a branch if you want to import it into your local
archive. So, why doesn't your second example work? Because once you've
gotten ucw--dev (which is what buildcfg uses to download the trees) you
can't tag it! Well, you can tag ucw-2004/ucw--dev, but then it just goes
out to common-lisp.net again. So you have to tag straight away, before
you've downloaded anything. support--dists really just gets in the way
of that. It's really just a tagging issue.

Granted, once you've done a 'tla get' you can do 'tla set-tree-version'
to your local archive and 'tla add-log-version' and then 'tla import',
but when you go and do that import, the logs get all messed up, and I
imagine you lose the seamless border between the archives (though I'm
not sure). So it's really not preferable.
