title: What's "@+node"?
body: <p>I'm trying to extend a Python + BottlePy script. I ran into a problem where my POST data are becoming <code>Null</code> during transmission, so I dived a little deeper into the code. In the web site templates, I found strings like <code>&lt;!--@+node:ngerum.20120101211222.1350: *3* settings--&gt;</code>, what do they mean? I didn't find anything in the BottlePy documentation and the only other used library is jQuery.</p>
