Version 0.2.1 of package Fsm has just been released in GNU ELPA.
You can now find it in M-x list-packages RET.
Fsm describes itself as:
=====================
State machine library
=====================

## Summary:
fsm.el is an exercise in metaprogramming inspired by gen_fsm of
Erlang/OTP. It aims to make asynchronous programming in Emacs Lisp
easy and fun. By "asynchronous" I mean that long-lasting tasks
don't interfere with normal editing.
Some people say that it would be nice if Emacs Lisp had threads
and/or continuations. They are probably right, but there are few
things that can't be made to run in the background using facilities
already available: timers, filters and sentinels. As the code can
become a bit messy when using such means, with callbacks everywhere
and such things, it can be useful to structure the program as a
state machine.
## Recent NEWS:
Version 0.2:
-- Delete trailing whitespace.
-- Fix formatting.
-- Use lexical binding.
-- Port to cl-lib.
-- Remove unnecessary fsm-debug-output message.
-- Add FSM name to fsm-debug-output messages that were not including it.
-- Fix checkdoc errors.
-- Change FSMs from plists to uninterned symbols.
NOTE: This is version 0.1ttn4 of fsm.el, with the following
mods (an exercise in meta-meta-programming ;-) by ttn:
-- Refill for easy (traditional 80-column) perusal.
-- New var `fsm-debug-timestamp-format'.
-- Make variables satisfy `user-variable-p'.
-- Use `format' instead of `concat'.
-- New func `fsm-goodbye-cruel-world'.
-- Make start-function respect `interactive' spec.
-- Make enter-/event-functions anonymous.
-- New macro `define-fsm'.
-- Example usage in Commentary.
