 * 2) WHAT THE SCRIPT DOES                                                         #
 * 3) This script is a wikipedia bot. It acts as a web spider. Given a wikipedia   #
 * 4) category page to start from, it finds all articles listed in that category   #
 * 5) as well as all subcategories of that category. For every subcategory it      #
 * 6) pulls a list of articles. For all articles retrieved (a list of all articles #
 * 7) in that category and its subcategories) it then retrieves the CLASS flag for #
 * 8) each page from wikipedia. It then presents these resulsts in tabulated form. #
 * 9) INTENDED USE                                                                 #
 * 10) It is intended that this script would be useful to those trying to monitor   #
 * 11) all pages within a category for purposes of administration or for a project  #
 * 12) in order to monitor which articles need bringing up from stub or start class #
 * 13) to full article status.                                                      #

 * 15) Code is formatted for ease of editing with Textad (www.textpad.com) or       #
 * 16) similar editor with colour-coding meta-markup. It may be difficult to scan   #
