I like 1.7 the best. :)
It's simple.
1.7. "License" means this document
I can show it to my daughter and say, "This is the License."
She will ask me, "What is the License?"
I answer, "The License is this document"
She asks me again, "What is that document?"
I answer, "This document is the License, CDDL."
".... OK, dad, BTW, why are you showing me the License, CDDL?" wonders she.
"Because it is very important. You will have to read it in future," said I.
"But, dad, it looks no fun. No picture!"
"Sorry but usually Licenses don't have pictures."
"Oh, is that so? Can you read me Winnie-the-Pooh with pictures page by page?"
"Sure, why not? I love it. I like Tigger and Piglet and Owl and Rabbit and...."
"I know, dad, don't tell me." :)
