Simple question - SVN labeling

Hello,

I'm trying to configure a specific build to tag the checkout of trunk.  It works if I checkout the whole project repository but doesn't work if I just checkout trunk.

Here's the following configuration that does work:

Checkout: <svn url>/<project>/
Labeling: trunk => tags

This works but checkouts all my trunk/tags/branches which obviously isn't ideal.

Here isn't what is working:

Checkout: <svn url>/<project>/trunk
Labeling: . => ../tags

I also tried trunk => tags but figured this would look for a folder called trunk in my trunk directory.  

Thanks,
Jeff
