"""This is a simple example of running a wsgi application with eventlet.
For a more fully-featured server which supports multiple processes,
multiple threads, and graceful code reloading, see:

import eventlet
from eventlet import wsgi

def hello_world(env, start_response):
    if env[‘PATH_INFO‘] != ‘/‘:
        start_response(‘404 Not Found‘, [(‘Content-Type‘, ‘text/plain‘)])
        return [‘Not Found\r\n‘]
    start_response(‘200 OK‘, [(‘Content-Type‘, ‘text/plain‘)])
    return [‘Hello, World!\r\n‘]

wsgi.server(eventlet.listen((‘‘, 8090)), hello_world)
