Script to update a Steam app folder in GNOME Shell

update-steam-app-folder.sh

#!/bin/bash

# WARNING: This script is totally awful and it'll probably blow up if you are unlucky.
# You have been warned.

# NOTE: This script assumes that you've already created an app folder called "Steam".
# Don't forget to give it a name too.
