 -- Virtual RPG Setup --
If you are reading this, you chose the correct
setup file for your architecture. There are a
couple of options available to you in this
setup script. Simply rerun this file with one
of the following:

 help - Which you found...it's this print-out

 systemd - This will install the VRPG service
 and enable it.

 clean - If you have issues with your setup
 you may use this option to clean the
 program of its setup files. You must use
 this when the setup fails. Otherwise, it
 will fail.
