-Each plugin has a reference to the Core object accessible with *self.core*, that allows you to do about anything with poezio. Remember to use it only when you need it, and to use the functions described in this documentation only, even if much more is available. If your plugin needs to do something not available with these methods, please do a feature request instead of doing some dirty hacks with some other methods.
