i like his entry on his faq about the build source
http://www.advsys.net/ken/buildsrc/default.htm:
"Why did you write a custom license instead of using GPL (GNU's General Public License)?
Short answer: to satisfy my ego

Long answer: I know GPL is an industry standard, but I felt that it was way too long and boring for anyone to read seriously. I chose to write a nice short license that everybody could understand. This way, people unfamiliar with GPL would understand their rights."
ah well its his code...
