"""Modular residential / rotating proxy provider package.

Selects a provider via the ``PROXY_PROVIDER`` env var (see ``registry.py``) and
exposes proxy settings in the formats different HTTP libraries expect. Add new
vendors by implementing :class:`ProxyProvider` in ``providers/`` and registering
them in ``registry.py``.
