If I understand that correctly when you enter directory with .ruby-version your ruby will switch. When you go deeper (like from Rails.root to Rails.root/script/) then it will reset. Right?

Maybe when you go deeper it should not reset? What do you think?

The elif [[ "$PWD" != "$RUBY_VERSIONED_DIRECTORY"/* ]]; then ensures you are still somewhere within the .ruby-version containing directory. Once you ascend outside of that directory, than it should reset.

Oh, right. I didn't notice /* at the end. Cool.
