The default About element has an explanation of the buttons used in
the document, controlled by SECTION_BUTTONS.
The formatting of this is influenced by
the text, description and example
direction strings (see Direction Strings) and by ACTIVE_ICONS
(see Simple Navigation Panel Customization).
PROGRAM_NAME_IN_ABOUT can also be used to change the beginning of
the About element formatting.
If the above is not enough and you want to control exactly the
formatting of the about element, the about special element body reference
function may be overridden (see Special Element Body Formatting Functions).
