/*#################Oil Standard v0.1#################This is a Greasemonkey script that changes all prices on a web page into the equivalent value in barrels of crude oil.A Play on words: Gold Standard... Standard Oil... Written by Michael Mandiberg (Michael [at] Mandiberg [dot] com)Lives at http://www.turbulence.org/Works/oilstandardOil Standard is a 2006 commission of New Radio and Performing Arts, Inc., (aka Ether-Ore) for its Turbulence web site. It was made possible with funding from the Jerome Foundation and New York City Department of CulturalAffairs.###################BARRELS AND GALLONS###################1 Barrel = 42 Gallons############INSTRUCTIONS############1. If you do not have the Firefox browser, you will need to download and install it from:http://www.mozilla.com/firefox/2. If you do not have the Greasemonkey extension installed, you will need to download and install it from:http://greasemonkey.mozdev.org/3. Once you have done these two things, refresh/reload this page, and youshould see an "Install" button on the upper right of your browser window.Simply click install, and it will be operational.4. Disable the script via the Greasemonkey menu in the bottom rightcorner of your browser. See the little monkey... clicking on the monkeyonce will disable Greasemonkey (clicking again, will re-enable it.)5. Remove the script by right-clicking (mac or pc)/control-clicking (mac) on the little monkey, and selecting "Manage User Scripts." From here youcan remove the script.#############Known Issues:#############When there are mulitple Million/Billion prices in succession, it ignores every other million suffix.####################Future Improvements:####################Set up the data retreivals to pull every hour, rather than every page loadAdd other currencies in addition to USD*///// ==UserScript==// @name Oil Standard// @namespace http://www.turbulence.org/Works/oilstandard// @description Converts all currency information into barrels of crude oil// @version 0.1// @date 2006-03-12// @creator Michael Mandiberg (Michael [at] Mandiberg [dot] com)// @include *// ==/UserScript==//// --------------------------------------------------------------------//// This is a Greasemonkey user script.//// To install, you need Greasemonkey: http://greasemonkey.mozdev.org/// Then restart Firefox and revisit this script.// Under Tools, there will be a new menu item to "Install User Script".// Accept the default configuration and install.//// To uninstall, go to Tools/Manage User Scripts,// select "Oil Standard", and click Uninstall.//// --------------------------------------------------------------------oilEntriesArray = new Array()oilLinksArray = new Array()// set the stylesaddGlobalStyle('.oillink { color: #996633 ! important;
