Yeah, I'll just throw this here seeing as the other main thread on here is so long - his website _is_ wild, and I'm not prepared or willing to go through and figure out where all we agree and disagree. BUT, the linked library is public domain, and the dude's website specifically says he's against forced attribution [0], so one should feel completely free to use the library and his other projects without even mentioning the author.
