UML is a widely accepted mechanism for describing state machines, so why shouldn't the tutorial make use of them?

I (very) recently used boost::fsm for the first time and I think arguably its best feature is the fact that the mapping
from a UML state-chart diagram to boost::fsm code is trivial. That allows me to design my state machine graphically
(which my brain prefers) and to then perform the transformation to code as a trivial step. So, in my opinion,
boost::fsm's relationship to UML is one of its primary features which deserves to be emphasised, not whacked in an appendix.

I might post a longer review if I get the chance, but my basic summary is that boost::fsm is far and away the best C/C++
library I've seen for implementing finite state machines simply and reliably. It has literally been a godsend for some
of the stuff I am trying to achieve.

So, a big thanks to Andreas, and whether boost::fsm makes it into boost or not, I'll still be using it :-)
