Rocket Web poured a ton of effort into this over the years but we're not going to use it anymore. So enjoy this, use it, make something new from it. But if you intend use any of this this commercially, you must obtain written permission from Matt MacDougall @ Rocket Web Inc. first. Matt will be very accomidating to small companies. If there's a larger company looking to make this into somehting as part of a big commercial effort, that will require negotiation.
