    Build a Docker image from a frecklet.

    This is just a proof-of-concept, to show that sometime like this is easily possible. It currently only works with Debian-based base images, as the pre-written Dockerfile template uses 'apt' to install curl. This would be easily changed once this is done properly.

      Don't use the Docker cache, and build the image even if an image named 'freckles-java-go' already exists.
