The <pre> tag stands for "PREformatted text"
and is useful when you want to insert a lot of
existing text into a Web page without having to
add a lot of HTML formatting tags.  It will
cause the text to be displayed almost exactly
as it is arranged in the HTML document.

The <pre> tag is also very useful for:
     - displaying indented lines
     - displaying lists of items
     - formatting text in unique ways
