Just came here to chime in and agree with @Muddledde. I love the idea of this shorter intro to cli programs, but it does seem to need a bit of updating. How can I help?

A smaller "jump already happens with 1.4, the error handling code is not really integrated into the earlier grss example. Rather, the example used in the error chapter is essentially independent from the code developed earlier (admittedly with some similarities).

An implementation of grss with improved error handling has been added at the end of chapter 1.4 (#233), but still the code is not developed incrementally into the given form.
