It's easy to read this from a YAML configuration file or from a DB, so
the actual list of commands is not hardcoded. It all depends on the
complexity of your application. Of course you can also use other
structures like a multidimensional array, or a unidimensional array
with [cmd1, msg1, cmd2, msg2...], but I like the hash cause it makes
clear what each element is. I'd rather not have arrays where you need
to know that the first element is something and the second is
something else, but for simple cases it might be enough. YMMV, though.
