I already considered removing that disclaimer. I should remove it. I will. Any moment now :\
Is there any other libs that you could recommend?
When I needed a plain state machine I just rolled my own following one of two patterns, the one from http://lua-users.org/wiki/FiniteStateMachine and the "functional" one (you can see an example of such machine parsing a protocol here: https://github.com/xopxe/lua-bencode-push/blob/master/bencode-push.lua). In these cases writing the machine felt pretty natural in the code itself, and I did not feel the need to use an abstracted library.
When the SM is more complex a library makes sense. We tried to use rFSM (https://github.com/kmarkus/rFSM), but run out of memory, and there seemed to be too much complexity in there. I just wrote a implementation based on its API. This is not the first time this happens to me, find a library with an API I want to use, find the implementation too complex or with lots of stuff I don't need, and then write my own library from scratch inspired by that. I suspect that means that the API is actually the hardest part of the library design.
