Cleaning up after Docker

Each time I build an image with docker, it gets tagged with the project identifier. You know, Something like ‘$ docker build -t cfreeman/reprage .’ The problem is that old images don’t get cleaned up, they just get left behind. Dangling until I clean them up, usually when I hit an inevitable ‘no space left on device’ error when building something.
