Just my interpretation of a static site generator.

Transforms (and watches) all .md, .markdown, .jade and .html files inside the articles folder and uses the templates/article.jade template to generate a static html file inside the generated folder.

A sorted list is passed to the templates/index.jade template to generate the generated/index.html file.

The files can have the following metadata:

title: The Title
author: Arpad Borsos
time: 2013-03-19T19:30:00.000Z
tags: this, is, currently-unused

And after those two newlines is when the actual content starts

        location / {
                root /var/www/generated;
                try_files $uri $uri.html $uri.xml $uri/index.html index.html @node;
                try_files /index.html @node;
        }
