That's very generous of you. Don't get angry though if I go ahead and re-publish all your code with your name replaced by mine. That's exactly what you are allowing me to do with such a license.
edit: to clarify, he's allowing you to _use_ it however you like, including making a derivative work, including it wholesale, etc. However, claiming authorship of the original code would still run afoul of the original copyright.
edit2: oh - if you mean relicensing the code - that is allowed.
