Angus Hollands 1436fb3ef4 Don't ask for uvloop on windows
This is a tricky issue, but essentially uvloop is unavailable on windows. This means for windows users, we have to install Sanic with no requirements, and then manually specify all requirements apart from uvloop.

However, Sanic will work with standard asyncio event loop. So, I propose we remove the uvloop requirement on windows. This patch doesn't touch any demo imports.

Sanic
=================================

|Join the chat at https://gitter.im/sanic-python/Lobby| |Build Status| |PyPI| |PyPI version|

Sanic is a Flask-like Python 3.5+ web server that's written to go fast.  It's based on the work done by the amazing folks at magicstack, and was inspired by `this article <https://magic.io/blog/uvloop-blazing-fast-python-networking/>`_.

On top of being Flask-like, Sanic supports async request handlers.  This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.

Sanic is developed `on GitHub <https://github.com/channelcat/sanic/>`_. Contributions are welcome!

Benchmarks
----------

All tests were run on an AWS medium instance running ubuntu, using 1
process. Each script delivered a small JSON response and was tested with
wrk using 100 connections. Pypy was tested for Falcon and Flask but did
not speed up requests.

Hello World Example
-------------------

.. code:: python

    from sanic import Sanic
    from sanic.response import json

    app = Sanic()

    @app.route("/")
    async def test(request):
        return json({"hello": "world"})

    if __name__ == "__main__":
        app.run(host="0.0.0.0", port=8000)

Installation
------------

-  ``python -m pip install sanic``

TODO
----
* Streamed file processing
* File output
* Examples of integrations with 3rd-party modules
* RESTful router

Limitations
-----------
* No wheels for uvloop and httptools on Windows :(
