/* This File was Created By Kris Cruickshank
 * This file contains the list of articles
 * on the PARABOW web site.
 * 
 * When this file "articles.js" is loaded it calls 
 * the function LoadPageList which Fills the two 
 * global arrays (arrayaPages & arrayDir) with 
 * article data.
 *
 *    ****************************
 *    ** How to use this script **
 *    ****************************
 *
 * If you have added an article to the website go to
 * one of the five sections:
 *
 *  1) Research Section
 *  2) Planning Section
 *  3) Building Section
 *  4) Training Section
 *  5) Results Section
 *
 * and then you copy the following three lines and paste 
 * them at the end of the section.

	arrayPages[x]	= "<<filename>>";
	arraySkip[x]	= false;
	arrayDir[x++]	= dir;
 
 * once you have inserted the above three lines at the end
 * of the relevent section change <<filename>> to the path 
 * name of the article that you added e.g.
 *
 *  "research/iceland/page_1.htm" 
 *
 *    - would reffer to the file whose full path would be
 *
 *  "http://localhost/parabow/projects/research/iceland/page_1.htm"
 *
 *    - You must remove every thing up to and including the 
 *      "projects/" directory.
 *
 * and then change the false on the second line to true if that
 * article loads a new sidebar.
