Pieter Hintjens on FSM, from the Libero documentation:

"ETK provides an interactive editor that you use to describe the logic of the program as a FSM. This approach encourages you to think about the complete problem. You describe everything that can happen, and how the program should react. The end- result looks a little like a flow-chart, but has more arrows, and fewer different kinds of boxes. The value of this approach is that you can abstract a complex problem using the restricted semantics of a FSM. In the same way that a While statement is less powerful but more useful than a Goto, a FSM is less powerful but more useful than a structured programming approach for describing complex problems. Leif Svalgaard once said: "the issue is not one of power, but coping with the human difficulty in understanding complex structures".
