Unix Utilities in Rust for Great Success

I've often been asked for suggestions for an appropriate first project in Rust, and I think that writing a version of a unix utility is a great choice, for a bunch of reasons!

I think whether you start with the book or a project like this depends on the learner.

I much prefer to jump in and struggle mightily, so I started with a project like this (what eventually became just), but I think a lot of people might prefer to start with the book, or at least parts of the book.
