We have a tool we "distribute" via Git - clone and run it.

README.md

Quick Start

Mac/Linux

git clone http://..../foo
cd foo
./foo.sh

Windows

Run with --help for more options.

      instructions,
      shell=True,
      check=True,
      capture=True,

    )

  assert result... # was it able to print help?
