Now you can run SPRNT in container. You can pull the docker image at this link:

https://hub.docker.com/r/frankliu1/sprnt

You will need to use the script util/run_sprnt_docker.sh. Another script util/run_docker.sh
allows you to specify other commands.

In order to use the container, make sure docker desktop is installed (Mac or Windows, x86_64 only). Details
can be found at https://docs.docker.com/.

Below is the screen output of running "run_sprnt_docker.sh m1.spt". Note the docker desktop automatically downloaded
the image from dockerhub:
