Despite the failing patch, I think it should be merged as it brings code that is related to the CLI, for which we do not introduce tests (as it is not really feasible). See the CLI directory.

Provides a solution for #157.

Looks good! Let's get this merged quickly to help out windows users 😄

@AbhinavTuli I agree, done!
