A simple library for generating the HTML and XML you need to interface with Google Checkout (google.com/checkout).  You can get a "Checkout" or "Buy Now" button with just a few lines of code.  Right now it depends on Rails's ActiveSupport library for 'builder/xmlmarkup' to generate the XML and Daiki Ueno's ruby-hmac library for signing the cart (http://deisui.org/~ueno/ruby/hmac.html).
