.. This file is included in README.rst from the top-level so it is limited to pure ReST markup, not Sphinx.

gevent is a coroutine_ -based Python_ networking library that uses greenlet <https://greenlet.readthedocs.io> to provide a high-level synchronous API on top of the libev or libuv_ event loop.

Features include:

Fast event loop based on libev or libuv.
Lightweight execution units based on greenlets.
API that re-uses concepts from the Python standard library (for examples there are events and queues).
Cooperative sockets with SSL support <http://www.gevent.org/api/index.html#networking>_
Cooperative DNS queries <http://www.gevent.org/dns.html>_ performed through a threadpool, dnspython, or c-ares.
Monkey patching utility <http://www.gevent.org/intro.html#monkey-patching>_ to get 3rd party modules to become cooperative
TCP/UDP/HTTP servers
Subprocess support (through gevent.subprocess_)
Thread pools
