To the author: if you really want to be permissive about what others can do with your software, a MIT, BSD, or Apache 2 license (which is more complete in that it even includes a patent grant) seem to be more widely recognized and well tested than the Unlicense. Unless you did choose that license for some solid reasons, I'd suggest to consider switching to one of the other better regarded licences.
