				YASM - Yet Another State Machine library

Lightweight library for creating function pointer based state machines

Copyright 2016/2017 bricofoy bricofoy@free.fr


Library provide basic functions for managing state machine execution
and state running timings and counts, and it is intended to be very 
easy to use.

Please see examples and README for documentation.
