I get very occasional requests for the source to the UTM applet. Often from people who want to incorporate UTM conversion into their own projects. I'm happy to send out the source but what I'd ask for is a contribution of 65 US dollars to help pay for the large amount of bandwidth the online applet is using (it has a lot of users).

If you want the source then enter the payment as one "UTM applet source" on the payment page, I'll see the payment come through and within a couple of days will email the latest source as a zip file to the email address given for the payment. Sometimes the yahoo mail system treats the payment notifications as spam so email me if there is an unusual delay.

The source comes "as is" and like the applet, is without any warranty as to it's correctness. It's structured in such a way that the conversion library itself is separate from the applet GUI so it's fairly straightforward to incorporate the library into other applications. All library classes have Javadoc comments which describe the method calls.
