We start this chapter with a very simple example around the std::filesystem::path class and a helper function that intelligently normalizes filesystem paths.
The result of this recipe is a little application that takes any filesystem path and returns us the same path in normalized form. Normalized means that we get an absolute path that contains no . or .. path indirections.
While implementing that, we will also see what details we need to pay attention to when working with this basic part of the filesystem library.
