License Notes

The "Unlicense" is similar to the Creative Commons Zero license, in that it is a legal construct intended to result in abandonment of any copyright where possible (and where not, license it under a permissive license similar to MIT). This is slightly different from a purely Public Domain work, because in some jurisdictions, the ability to place a work into the Public Domain is unclear. It is Free and GPL Compatible, whether the code is perceived to be in the public domain or under the permissive license terms.

[NOTE: The first sentence of the following paragraph no longer reflects Fedora policy as of 2022-08-01, with respect to licensing of code]

Fedora recommends use of CC-0 over this license, because it is a more comprehensive legal text around this tricky issue. It is also noteworthy that some MIT variant licenses which contain the right to "sublicense" are closer to a true Public Domain declaration than the one in the "Unlicense" text.
