        // This is a ruby implementation of the VideoEgg (www.videoegg.com) integration library. You will need to create a developer account on the website, and put in the appropriate authentication items. Although this was meant for Rails, you could probably use it anywhere with Ruby. For Rails, simply put it in your lib/ folder, and call VideoEgg.embed_publisher or VideoEgg.embed_player in your template.
