     Lorem Ipsum is simply dummy text of the printing and typesetting industry. 
     Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,
	 when an unknown printer took a galley of type and scrambled it to make a type 
	 specimen book. It has survived not only five centuries, but also the leap into 
	 electronic typesetting, remaining essentially unchanged. It was popularised in the
	 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more
	 recently with desktop publishing software like Aldus PageMaker including versions of
	 Lorem Ipsum.
