			// 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.

			// We search VPK files before ordinary folders, because most files will be found in
			// VPK and we can avoid making thousands of file system calls to attempt to open files
			// in folders where they don't exist.  (Searching a VPK is much faster than making an operating
			// system call.)
