To use this you will first need to install Docker.
https://docs.docker.com/install/

I wrote this on Linux and have not tested on other OSes.  In theory,
it should work on Mac and Windows too.

After installing Docker, use a shell in the same directory as these files and
run the following commands:

docker build -t ml_build .
docker rm ml_build_output
docker create --name ml_build_output ml_build https://github.com/reticulatedpines/magiclantern_simplified
docker start --attach ml_build_output
docker cp ml_build_output:/home/ml_builder/ml_build/magiclantern.zip .

The "docker rm" command may give an error; this can be ignored.
