Development was done on equipment of my employer Luciad, a great Java GIS company with friendly people.
The project is hosted at SourceForge.
My colleagues at Luciad have been very patient working with early versions of the code. Since the first public release, others have chimed in with interesting ideas, bug reports, and bug fixes: Thorsten Heit, Oliver Retzl, Jonathan Knudsen, Bob Drury, Dave Jarvis, Marc Chapman, Dave Morehouse, and Richard Osbaldeston. Thanks! Your feedback has been invaluable.
The code and these web pages were written using Sun JDK 1.3.1, Borland JBuilder, IntelliJ IDEA, GNU emacs, bash, sed, awk, and a whole host of other free tools which continue to make programming interesting.
