	// After MacOS X 10.1 when a new load command is added that is required to be
	// understood by the dynamic linker for the image to execute properly the
	// 'Required' bit will be or'ed into the load command constant.  If the dynamic
	// linker sees such a load command it it does not understand will issue a
	// "unknown load command required for execution" error and refuse to use the
	// image.  Other load commands without this bit that are not understood will
	// simply be ignored.
