 The scripts directly under `build/` are used to build and test.

If necessary (for Mac OS X), the scripts will also copy results out.

 Everything in `build/build-image/` is meant to be run inside of the container.  If it doesn't think it is running in the container it'll throw a warning.  While you can run some of that stuff outside of the container, it wasn't built to do so.
 
-The files necessarily for the release Docker images are in `build/run-images/*`.  All of this is staged into `output/images` similar to build-image.  The `base` image is used as a base for each of the specialized containers and is generally never pushed to a shared repository.
