<h1>Eventlet</h1>
<p>Eventlet is a networking library written in Python. It achieves high scalability by using <a class="reference external" href="http://en.wikipedia.org/wiki/Asynchronous_I/O#Select.28.2Fpoll.29_loops">non-blocking io</a> while at the same time retaining high programmer usability by using <a class="reference external" href="http://en.wikipedia.org/wiki/Coroutine">coroutines</a> to make the non-blocking io operations appear blocking at the source code level.</p>
<h3>Documentation</h3>
<a href="doc/">API Documentation</a>
<h3>Installation</h3>
<p>To install eventlet, simply:
<pre>
easy_install eventlet
</pre></p>
<p>Alternately, you can download the source tarball:
<ul>
<li><a href="http://pypi.python.org/packages/source/e/eventlet/eventlet-0.8.12.tar.gz#md5=f9888a6b4135a2c124200d233f5f5829">eventlet-0.8.12.tar.gz</a></li>
</ul>
</p>
<h3>Mailing List</h3>
<p><a href="https://lists.secondlife.com/cgi-bin/mailman/listinfo/eventletdev">eventletdev at lists.secondlife.com</a></p>
<p>This is a relatively low-traffic list about using and developing eventlet. Look through the <a href="https://lists.secondlife.com/pipermail/eventletdev/">archives</a> for some useful information and possible answers to questions.</p>
<h3>Development</h3>
<p><a href="http://bitbucket.org/which_linden/eventlet/">"root" repository</a></p>
<p>We use Mercurial for our source control, hosted by BitBucket. It's easy to branch off the main repository and contribute patches, tests, and documentation back upstream.</p>

<h2>Web Crawler Example<a class="headerlink" href="#web-crawler-example" title="Permalink to this headline"></a></h2>
<p>This is a simple web &#8220;crawler&#8221; that fetches a bunch of urls using a coroutine pool. It has as much concurrency (i.e. pages being fetched simultaneously) as coroutines in the pool.</p>
