Jekyll is a simple, blog aware, static site generator. It takes a template directory (representing the raw form of a website), runs it through Textile or Markdown and Liquid converters, and spits out a complete, static website suitable for serving with Apache or your favorite web server.

This is also the engine behind GitHub Pages (http://pages.github.com), which you can use to host your project's page or blog right here from GitHub.

There are lot of plugins available and only the most common ones are suggested by the package. Look for more using 'jekyll plugin'.
