---- 'root_dir' is chosen like this:
---- if two or more directories containing `mix.exs` were found when searching
---- directories upward, the second one (higher up) is chosen, with the
---- assumption that it is the root of an umbrella app. Otherwise the directory
---- containing the single mix.exs that was found is chosen.
