Twitter Bootstrap的doc网站是如何制作的？

Question

我的意思是这个网站：http://getbootstrap.com/

我查看了https://github.com/twbs/bootstrap/tree/master/docs

处的代码

我认为.html不是典型的HTML？例如

对于CSS page，source code为：

---
layout: default
title: CSS
slug: css
lead: "Global CSS settings, fundamental HTML elements styled and enhanced with extensible classes, and an advanced grid system."
---


{% include css/overview.html %}
{% include css/grid.html %}
{% include css/type.html %}
{% include css/code.html %}
{% include css/tables.html %}
{% include css/forms.html %}
{% include css/buttons.html %}
{% include css/images.html %}
{% include css/helpers.html %}
{% include css/responsive-utilities.html %}
{% include css/less.html %}
{% include css/sass.html %} 

具体来说，编程语言，构建网站的框架是什么？

略读build program表明它使用了Jekyll，这是用Ruby编写的。
