Test v02 - Pnetlab & ishare2 Installation Script OpenSuse

#!/bin/bash
# Version 002 - Altered by ph4ntom74 - 11th December 2023.
# Still needs to add "alien" to convert .deb to .rpm packages.
# The idea is t,o have a script to install pnetlab on an Tumbleweed
# desktop without the need of VMware Workstation. Maybe its a stupid
# idea but hey, I'm not a coder.

# Open debugging output
