		// First, mount all user customizations. This will search for VPKs and subfolders
		// and mount them in alphabetical order. The easiest way to distribute a mod is to
		// pack up the custom content into a VPK. To "install" a mod, just drop it in this
		// folder.
		//
		// Note that this folder is scanned only when the game is booted.
		game+mod garrysmod/custom/*

		// Now search loose files. We'll set the directory containing the gameinfo.txt file

		// We search VPK files before ordinary folders, because most files will be found in

		// in folders where they don't exist. (Searching a VPK is much faster than making an operating
