Plugin and hook calling mechanisms for Python

pluggy is the crystallized core of plugin management and hook calling for pytest. It enables 500+ plugins to extend and customize pytest's default behaviour. Even pytest itself is composed as a set of pluggy plugins which are invoked in sequence according to a well defined set of protocols. It gives users the ability to extend or modify the behaviour of a host program by installing a plugin for that program. The plugin code will run as part of normal program execution, changing or enhancing certain aspects of it. In essence, pluggy enables function hooking so you can build "pluggable" systems.
