mdpress – Present your markdown file in slideshow

I have been using reveal.js to create slideshow from markdown. It’s very nice and powerful. But the setup is a bit complicated. Sometimes i want to have a more simple solution.

Without the web development framework like Python Django or Ruby on Rails which bundle with pserver and WEBrick, i would like to find a light weight web server such that i could edit and preview my markdown which runs on reveal.js. Finally i find Mongoose.
