tourist information
     
        Information in an on-line display that is not immediately
        useful, but contributes to a viewer's gestalt of what's going
        on with the software or hardware behind it.  Whether a given
        piece of info falls in this category depends partly on what
        the user is looking for at any given time.  The "bytes free"
        information at the bottom of an {MS-DOS} "dir" display is
        tourist information; so (most of the time) is the TIME
        information in a {Unix} "ps(1)" display.
