What does the resulting image look like?

Would it be enough to generate an =E2=80=9CImage JSON Description=E2=80=9D =
in this
format: <https://github.com/docker/docker/blob/master/image/spec/v1.md>?

I=E2=80=99m not familiar enough with Docker but I=E2=80=99m under the impre=
ssion that we
should be able to generate an image without even using Docker.  :-)

Thanks for sharing the neat hack!
