What is Lorem Ipsum?
Lorem Ipsum is simply dummy text of the printing and typesettingindustry.
Lorem Ipsum has been the industry's standard dummy text eversince the 1500s,
when an unknown printer took a galley of type andscrambled it to make a type specimen book.
It has survived not only fivecenturies, but also the leap into electronic typesetting,
remainingessentially unchanged. It was popularised in the 1960s with the
release ofLetraset sheets containing Lorem Ipsum passages, and more recently
withdesktop publishing software like Aldus PageMaker including versions ofLorem Ipsum.
