+    \ Test coverage\n\nThe async_generator library\n===========================\n\nPython 3.6 added `async generators\n<https://www.python.org/dev/peps/pep-0525/>`__. (What's an async\ngenerator? `Check\
+    \ out my 5-minute lightning talk demo from PyCon 2016\n<https://youtu.be/PulzIT8KYLk?t=24m30s>`__.) Python 3.7 adds some more\ntools to make them usable, like ``contextlib.asynccontextmanager``.\n\n\
+    This library gives you all that back to Python 3.5.\n\nFor example, this code only works in Python 3.6+:\n\n.. code-block:: python3\n\n   async def load_json_lines(stream_reader):\n       async for\
+    \ line in stream_reader:\n           yield json.loads(line)\n\nBut this code does the same thing, and works on Python 3.5+:\n\n.. code-block:: python3\n\n   from async_generator import async_generator,\
+    \ yield_\n\n   @async_generator\n   async def load_json_lines(stream_reader):\n       async for line in stream_reader:\n           await yield_(json.loads(line))\n\nOr in Python 3.7, you can write:\n\
+    \n.. code-block:: python3\n\n   from contextlib import asynccontextmanager\n\n   @asynccontextmanager\n   async def background_server():\n       async with trio.open_nursery() as nursery:\n        \
+    \   value = await nursery.start(my_server)\n           try:\n               yield value\n           finally:\n               # Kill the server when the scope exits\n               nursery.cancel_scope.cancel()\n\
+    \nThis is the same, but back to 3.5:\n\n.. code-block:: python3\n\n   from async_generator import async_generator, yield_, asynccontextmanager\n\n   @asynccontextmanager\n   @async_generator\n   async\
+    \ def background_server():\n       async with trio.open_nursery() as nursery:\n           value = await nursery.start(my_server)\n           try:\n               await yield_(value)\n           finally:\n\
+    \               # Kill the server when the scope exits\n               nursery.cancel_scope.cancel()\n\n(And if you're on 3.6, you can use ``@asynccontextmanager`` with\nnative generators.)\n\n\nLet's\
+    \ do this\n=============\n\n* Install: ``python3 -m pip install -U async_generator`` (or on Windows,\n  maybe ``py -3 -m pip install -U async_generator``\n\n* Manual: https://async-generator.readthedocs.io/\n\

+    \ in\n  all project spaces.\n\n\nHow come some of those links talk about \"trio\"?\n===============================================\n\n`Trio <https://trio.readthedocs.io>`__ is a new async concurrency\n\
+    library for Python that's obsessed with usability and correctness \u2013 we\nwant to make it *easy* to get things *right*. The ``async_generator``\nlibrary is maintained by the Trio project as part\
+    \ of that mission, and\nbecause Trio uses ``async_generator`` internally.\n\nYou can use ``async_generator`` with any async library. It works great\nwith ``asyncio``, or Twisted, or whatever you like.\
+    \ (But we think Trio\nis pretty sweet.)\n\n\n"

+  summary: An async/await-native I/O library for humans and snake people
+  description: ".. image:: https://cdn.rawgit.com/python-trio/trio/9b0bec646a31e0d0f67b8b6ecc6939726faf3e17/logo/logo-with-background.svg\n   :width: 200px\n   :align: right\n\nThe Trio project's goal is\
+    \ to produce a production-quality, `permissively\nlicensed <https://github.com/python-trio/trio/blob/master/LICENSE>`__,\nasync/await-native I/O library for Python. Like all async libraries,\nits main\
+    \ purpose is to help you write programs that do **multiple\nthings at the same time** with **parallelized I/O**. A web spider that\nwants to fetch lots of pages in parallel, a web server that needs\
+    \ to\njuggle lots of downloads and websocket connections at the same time, a\nprocess supervisor monitoring multiple subprocesses... that sort of\nthing. Compared to other libraries, Trio attempts to\
+    \ distinguish\nitself with an obsessive focus on **usability** and\n**correctness**. Concurrency is complicated; we try to make it *easy*\nto get things *right*.\n\nTrio was built from the ground up\
+    \ to take advantage of the `latest\nPython features <https://www.python.org/dev/peps/pep-0492/>`__, and\ndraws inspiration from `many sources\n<https://github.com/python-trio/trio/wiki/Reading-list>`__,\
+    \ in\nparticular Dave Beazley's `Curio <https://curio.readthedocs.io/>`__.\nThe resulting design is radically simpler than older competitors like\n`asyncio <https://docs.python.org/3/library/asyncio.html>`__\
+    \ and\n`Twisted <https://twistedmatrix.com/>`__, yet just as capable. Trio is\nthe Python I/O library I always wanted; I find it makes building\nI/O-oriented programs easier, less error-prone, and just\
+    \ plain more\nfun. Perhaps you'll find the same.\n\nThis project is young and still somewhat experimental: the overall\ndesign is solid and the existing features are fully tested and\ndocumented, but\
+    \ you may encounter missing functionality or rough\nedges. We *do* encourage you do use it, but you should `read and\nsubscribe to issue #1\n<https://github.com/python-trio/trio/issues/1>`__ to get\
+    \ warning and a\nchance to give feedback about any compatibility-breaking changes.\n\nVital statistics:\n\n* Supported environments: Linux, MacOS, or Windows running some kind of Python\n  3.5-or-better\
+    \ (either CPython or PyPy3 is fine). \\*BSD and illumus likely\n  work too, but are not tested.\n\n* Install: ``python3 -m pip install -U trio`` (or on Windows, maybe\n  ``py -3 -m pip install -U trio``).\
+    \ No compiler needed.\n\n* Tutorial and reference manual: https://trio.readthedocs.io\n\n* Bug tracker and source code: https://github.com/python-trio/trio\n\n* License: MIT or Apache 2, your choice\n\
+    \n* Contributor guide: https://trio.readthedocs.io/en/latest/contributing.html\n\n* Code of conduct: Contributors are requested to follow our `code of\n  conduct\n  <https://trio.readthedocs.io/en/latest/code-of-conduct.html>`_\n\
