/**
 * This file defines a blog theme for PhpWiki,
 * based on Rui Carmo's excellent http://the.taoofmac.com/space/
 * which is based on the Kubrick theme: http://binarybonsai.com/kubrick/
 * The layout was designed and built by Michael Heilemann,
 * whose blog you will find at http://binarybonsai.com/
 *
 * [Stanley Kubrick]"Good afternoon, gentlemen. I am a HAL 9000
 * computer. I became operational at the H.A.L. plant in Urbana,
 * Illinois on the 12th of January 1992. My instructor was
 * Mr. Langley, and he taught me to sing a song. If you'd like to hear
 * it I can sing it for you."
 *
 * The CSS, XHTML and design is released under GPL:
 * http://www.opensource.org/licenses/gpl-license.php
 *
 * Default is a one-person (ADMIN_USER) blog (at the BlogHomePage), but
 * other blogs are also enabled for every authenticated user.
 *
 * Actionbar: Edit, Home, About, Archives, News, ..., Info  [ Search ]
 * PageTrail: > .. > ..
 * Right sidebar boxes: Archives, Syndication, Links, GoogleAds
 *
 * For the livesearch feature (autodropdown of the results while you tip)
 * you'll have to copy livesearch.js from http://blog.bitflux.ch/wiki/LiveSearch
 * to themes/default/, change the liveSearchReq.open line to:
liveSearchReq.open("GET", liveSearchURI + "?format=livesearch&paging=none&limit=25&s=" + document.forms.searchform.s.value);
 * and define ENABLE_LIVESEARCH in config.ini to true.
 *
 * Better autodropdown's are in consideration:
 *   http://momche.net/publish/article.php?page=acdropdown)
 *
 * Happy blogging.
