Hello, I am pleased to announce Payment, an easy to use payment gateway 
for Ruby.

Take a look at the project page at 
http://rubyforge.org/projects/payment/ or for those of you who have 
rubygems, go to your command line and type:

gem install payment

Currently, Authorize.Net is the only gateway it supports, but more 
gateways are going to be built very soon. I hope this project fills a 
need for this great community. I am planning on adding Rails 
integration to the payment gateway for a Billing generator of sorts.

The Trac install can be found at http://payment.rufy.com/ for those 
interested in contributing to this project.
