    This script adds a graphical button bar to the edit page form.
    The buttons are placed in the $GUIButtons array; each button
    is specified by an array of five values:
      - the position of the button relative to others (a number)
      - the opening markup sequence
      - the closing markup sequence
      - the default text if none was highlighted
      - the text of the button, either (a) HTML markup or (b) the 
        url of a gif/jpg/png image to be used for the button 
        (along with optional "title" text in quotes).

    The buttons specified in this file are the default buttons
    for the standard markups.  Some buttons (e.g., the attach/upload
    button) are specified in their respective cookbook module.
