State machines describe the different stages or states of a thing's lifeline, the events that influence changes between those states, and the actions taken in response to events at each state. They provide a complete specification of a thing's dynamic behavior. This document introduces state machines and their motivation, including provable programs, minimal code, and ease of integration with inotify, making them well-suited for embedded Linux systems. It then provides an example C++ code snippet of a state machine transition table.

2. WHAT ARE STATE MACHINES?
State machines are the description of a thing's lifeline. They describe the
different stages of the lifeline, the events influencing it, and what it does
when a particular event is detected at a particular stage. They offer the
complete specification of the dynamic behavior of the thing.

3. MOTIVATION
Provable Programs
Minimal Code
Small Executable
Easy integration with inotify
Component style object files
Little syntactic noise as possible
Faster Execution Time
Reduce dependencies
Maintainable and fairly easy to work on
Nice for embedded Linux system
Easy deploy against common boxes in cloud

4. STATE MACHINE, STATE, TRANSITION, EVENT

6. THIS IS C++ CODE … REALLY THIS IS THE PROGRAM
BOOST_MSM_EUML_TRANSITION_TABLE((
Playing == Stopped + play [some_guard] / (some_action , start_playback) ,
Open == Stopped + open_close/ open_drawer ,
Stopped == Stopped + stop ,
Empty == Open + open_close / close_drawer ,
Open == Empty + open_close / open_drawer ,
Stopped == Empty + cd_detected [good_disk_format] / store_cd_info),transition_table
