 * Linux Today Butler
 * version 0.1.1
 * 2005-03-24
 * Copyright (c) 2005, Denis McLaughlin
 * Released under the GPL license, version 2

 * Inspired by Julien Couvreur's BoingBoing Butler

 ******************************************************************************
 *
 * Well, the folks who run Linux Today do a fine job of collecting Linux
 * related articles, but those sidebars squeezing the content are just nasty.
 * So this sorts that out, inspired in principal by the BoingBoing Butler,
 * and with details from other Greasemonkey scripts, since I don't know
 * jack about javascript.
 *
 * The formats of Linux Today's front page and the per-article pages are
 * slightly different, so I've distinguished between them.  Since the various
 * tables don't use names, I just set the visibility of the specific tables
 * to none: if the format of the page changes, this script may break.

 * Requirements:
 *  - Firefox
 *  - Greasemonkey http://greasemonkey.mozdev.org/
 *  - an interest in viewing linuxtoday.com without the sidebars
 *
 * To Install:
 *  - like any greasemonkey script: install greasemonkey, restart FF, open
 *    this script in a browser window, go to Tools/Install User Script

 * To Uninstall:
 *  - like any greasemonkey script: Tools/Manage User Scripts, select Linux
 *    Today Butler, click the Uninstall button
 *
 * Changelog:
 *    March 30, 2005
 *    Denis McLaughlin
 *    - tweaked to follow latest format linuxtoday.com structure
 *    - added slightly more robust table removal
 *    - changed documentation to describe removal of sidebars, rather
 *      than just ads
