TCP Port Listener
// This is a very basic TCP port listener that allows you to listen on a port range
// If you run this program outside of firewall and run a port scanner inside a firewall
// pointing to the ip address where this program runs, the port scanner will be able you
// to tell which exactly ports are open on the firewall
// This code will run on Windows, but most importantly also on linux.
// DigitalOcean.com has all ports for their VMs open by default. So spin a new VM,
// copy pln.cs in your (root) home folder and then run:
// sudo apt-get update
// sudo apt-get install mono-complete -y
// mcs pln.cs

Creates shortcuts of your whole installed steam library in a folder on your destop
// Creates shortcuts of your whole installed steam library in a folder on your destop
// Note 1: icons for some games do not get set correctly, but than they do not get set correctly by steam itself either
// Note 2: code heavily depends on the steam interal file formats so this can stop working without notice any time
// Note 3: this code does not have any command line arguments, it tries to detect path to your steam folder
// if it can't feel free to modify it to hardcode the path. Similarily you can change where the shortcuts
// are written to in the code. Sorry, not a user friendly tool at all - you are assumed to be a developer
