Nested collections have some issues with tags:

nested 1.0 requirements: - implement :TAG: - block tags in components until this is complete. - sparse tags can come later - figure out the bk tag syntax cd gcc bk tag gcc.stable # works, has the right prefix bk tag stable # either is a product tag or is an error perhaps bk tag ./stable # means tag this component bk changes -r./stable # means gcc.stable bk -A tag ./stable # do a tag in everything (for detach) # makes ./<tag> pretty compelling
