 gevent_
 =======
 
-gevent_ is a Python networking library that uses greenlet_ to provide synchronous API on top of libevent_ event loop.
+gevent_ is a coroutine-based Python networking library.
 
 Features include:
 
-* Fast event loop based on libevent_.
+* Fast event loop based on libev_.
 * Lightweight execution units based on greenlet_.
 * Familiar API that re-uses concepts from the Python standard library.
 * Cooperative sockets with ssl support.
-* DNS queries performed through libevent-dns.
+* DNS queries performed through c-ares_.
 * Ability to use standard library and 3rd party modules written for standard blocking sockets
-* Fast WSGI server based on libevent-http.
 
 gevent_ is `inspired by eventlet`_ but features more consistent API, simpler implementation and better performance. Read why others `use gevent`_ and check out the list of the `open source projects based on gevent`_.

-gevent is a Python networking library that uses greenlet_ to provide a synchronous API on top of libevent_ event loop.
+gevent is a coroutine-based Python networking library.
 
 Features include:
 
-* Fast event loop based on libevent (epoll on Linux, kqueue on FreeBSD).
+* Fast event loop based on libev (epoll on Linux, kqueue on FreeBSD).
 * Lightweight execution units based on greenlet.
 * API that re-uses concepts from the Python standard library (e.g. :class:`Event`, :class:`Queue`).
 * Cooperative :mod:`socket` and :mod:`ssl` modules.
 * Ability to use standard library and 3rd party modules written for standard blocking sockets (:mod:`gevent.monkey`).
-* DNS queries performed through libevent-dns.
-* Fast WSGI server based on libevent-http.
