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.
