use the latter approach, and can serve as a good example.
+There is another possible reason for preferring lower-level bindings:

The task is to create easy to use Hurd bindings for a language of the student's
choice, and some example servers to prove that it works well in practice. This
project will require gaining a very good understanding of the various Hurd
