  The following legacy code is created by blocco.
	
	This code was made to be run by "server.lua".
	It was an attempt at server-sided commands with permission levels.
	There is even a zone to add your own commands.
	
	It contains many comments for documentation purposes.
	It is to be used for educational purposes.
	
	This code is from RBXPri (Blocco Edition).
	This file is "commands.lua".
