Assess the line coverage for Python and compiled language source files retroactively over the history of the SciPy project using a Docker-based approach.

build Docker image in repo root with: docker build -t scipy-cov .

specify the dependency versions using environment variables (i.e., in a file), and run the docker container to probe line coverage with a command like this: docker run -it --env-file env_files/env-scipy-1.0.0 --mount type=bind,source="$(pwd)"/container_output,target=/container_output scipy-cov
