"When you create a text file, you can use a special set of
delimiters to define a header, a body, and a footer. As you can see
in the illustration, you do this by placing the appropriate series
of backslashes and colons at the start of each section. Three of
each character defines the header, two of each defines the body,
and one of each defines the footer. The nl utility allows you to
number each of these sections in its own way."
