I can't get the tagging option to work when I build images.

hub: &hub
  image: "radial/hub-base:latest"
  detach: true
  name: hub
  restart: always
  volumes-from:
    - logs
    - cache

hubDynamic:
  <<: *hub
  volumes:
    - /config
    - /data
    - /run

hubStatic:
  <<: *hub

Building "hubStatic from a different directory I run:
fugu build --path hub/ hubStatic --tag="hub"

But this names the resulting image the same as the source:

docker build --tag="radial/axle-base:latest" hub/

So I thought about ordering? Thinking that fugu had it's own --tag option...

○ fugu build --path hub/ --tag="hub" hubStatic
docker build hub/

no dice. What you think? Where does that --tag option go?
