// email: aaron@deadskunk.org
// purpose: Returns a table containing the latest news from www.commondreams.org (a political site with a lefty bent).
// use: Just paste this somewhere in a script and it will output the table with the headlines
// notes: Just something I threw together for my website (www.deadskunk.org -- has an example on the main page) as all
// the news grabbing stuff is either too geeky or too corporate for my tastes. Edit as much as you want, send
// me an email if you have questions/comments.
