Re: notices for CC0

[Alfred M. Szmidt]

        So should GNU maintainers add copyright lines to CC0d files? what
        about non-gnu Savannah programs? which recommendation applies to them?
        what should the hosting requirement be (we routinely point
        to GNU Maintainer Info to tell how software should be packaged)?

   I don't think GNU programs should have any non-trivial files CC0.  

And even for that the GNU project has guidelines:
