/**
 * A simple script for easily serving a folder containing static website.
 * It's shamelessly snatched from https://gist.github.com/ryanflorence/701407
 * and might be vurnerable to directory traversal attack, yet I've not been
 * able to make such an attack work.
 * 
 * TODO: maybe fix ugly repetitiveness?
