help_message="Super cool system setup utility that downloads all the packages you could possibly need!\n
How to use this bad boy:\n\n
\t--help - show this help message and leave\n
\t--list - list what is in given preset and leave. You can only use this option with --preset!\n
\t--preset - choose a preset you want to use\n
\t--services - enable all services after installing packages\n
\t--install - installs given preset to your system\n
\t--uninstall - uninstall given preset from your system. Possibly very stupid, because presets contain important system packages, like your window manager!\n\n
Thanks for using my super cool script :D
