stevedore

Python makes loading code dynamically easy, allowing you to configure and extend your application by discovering and loading extensions (“plugins”) at runtime. Many applications implement their own library for doing this, using import or importlib. stevedore avoids creating yet another extension mechanism by building on top of setuptools entry points. The code for managing entry points tends to be repetitive, though, so stevedore provides manager classes for implementing common patterns for using dynamically loaded extensions.
