Zope.proxy provides generic, transparent proxies for Python. Proxies are special objects which serve as mostly-transparent wrappers around another object, intervening in the apparent behavior of the wrapped object only when necessary to apply the policy (e.g., access checking, location brokering, etc.) for which the proxy is responsible.

Zope.location implements the concept of "locations" in Zope3, which are are special objects that have a structural location.

Often, especially for package modules, you want to import names for convenience, but not actually perform the imports until necessary. The zope.deferredimport package provided facilities for defining names in modules that will be imported from somewhere else when used. You can also cause deprecation warnings to be issued when a variable is used.

Eventlet is a concurrent networking library for Python that allows you to change how you run your code, not how you write it. It uses epoll or libevent for highly scalable non-blocking I/O. Coroutines ensure that the developer uses a blocking style of programming that is similar to threading, but provide the benefits of non-blocking I/O. The event dispatch is implicit, which means you can easily use Eventlet from the Python interpreter, or as a small part of a larger application.

Note: In Guix, this package assumes the environment variable EVENTLET_NO_GREENDNS defaults to yes. To try to use it, set it to anything else.

zconfig is a configuration library intended for general use. It supports a hierarchical schema-driven configuration model that allows a schema to specify data conversion routines written in Python. Its model is very different from the model supported by the configparser module found in Python's standard library, and is more suitable to configuration-intensive applications.

WhiteNoise allows your web app to serve its own static files, making it a self-contained unit that can be deployed anywhere without relying on nginx, Amazon S3 or any other external service.
