I notice your code has two licenses in the repository and since one of them releases the code into the public domain while the other is the GPL I was a bit confused. Are you releasing the code under both licenses?

I'm asking, because I was interested in creating a patch to zotero to improve djvu support and I wanted to first check the licenses were compatible and it's not completely clear when and what versions of the GPL are compatible with the AGPLv3. If you are also releasing it under the unlicense no problem.

Though as a matter of curiosity why wouldn't you just release it under the unlicense given that it allows people to do everything the gpl allows and more?
