I think you are wrong here. quoting http://en.wikipedia.org/wiki/Public_domain_software: "Under the Berne Convention, which most countries have signed, an author automatically obtains the exclusive copyright to anything they have written, and local law may similarly grant copyright, patent, or trademark rights by default. The Berne Convention also covers programs. Therefore, a program is automatically subject to a copyright, and if it is to be placed in the public domain, the author must explicitly disclaim the copyright and other rights on it in some way." Note the wording "explicitly disclaim". While German law has something like a "triviality threshold" which may well apply to very small code snippets, i'd say "no included license" by default means "all rights reserved". Regards, Michael
