Usage: jutge-test-run <image-name> <command> [args...]

    Execute commands in a container using one of the Jutge images.

    The <image-name> will be prefixed with "jutgeorg/" (so you don't need
	to include it). Available images are stored at Docker Hub
	(https://hub.docker.com/u/jutgeorg).
	
	Example <image-name>s: "gcc", "python", "java", "haskell" and "extra".

    This test version maps the current directory as /home/worker in the 
    container, sets the UID to the current user (to avoid permission issues)
	and starts the command interactively.
