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/oilstandard
Oil 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 Cultural
Affairs.
###################
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 you
should 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 right
corner of your browser. See the little monkey... clicking on the monkey
once 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 you
can 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 load
Add other currencies in addition to USD
