-The option ``license'' \newFeature{0.22.2} is also optional technically (for backward compatibility), but we highly recommended define it for your sky culture.

+The option ``license'' \newFeature{0.22.2} is technically optional

+(for backward compatibility; it defaults to ``unknown''), but we

+highly recommend to define it for your sky culture, and it is

+mandatory if you want your skyculture to be distributed with

+Stellarium to prevent ``unexpected'' distribution of your content to other

+software out of our hands.  The license info will be decoded for human

+readable hints about allowed permissions for sky culture in the GUI.

+We recommend to use one of the following possible licenses in this section: 

 \begin{description}

-  \item[GNU GPL] -- this is most famous ``copyleft'' license for the code and it may be acceptable also for text and data.

-  \item[CC BY (Creative Commons Attribution License)] -- this license lets others distribute, remix, adapt, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.

-  \item[CC BY-SA (Creative Commons Attribution-ShareAlike License)] -- this license lets others remix, adapt, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This license is often compared to ``copyleft'' free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.

-  \item[CC BY-ND (Creative Commons Attribution-NoDerivs License)] -- this license lets others reuse the work for any purpose, including commercially; however, it cannot be shared with others in adapted form, and credit must be provided to you.

-  \item[CC BY-NC (Creative Commons Attribution-NonCommercial License)] -- this license lets others remix, adapt, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.

-  \item[CC BY-NC-SA (Creative Commons Attribution-NonCommercial-ShareAlike License)] -- this license lets others remix, adapt, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms.

-  \item[CC BY-NC-ND (Creative Commons Attribution-NonCommercial-NoDerivs License)] -- this license is the most restrictive of six main Creative Commons licenses, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.

+  \item[GNU GPL v2.0 (or later)] -- this is the most famous ``copyleft'' license for code and it may be acceptable also for text and data.

+  \item[CC0] (No Rights Reserved) -- this is a ``don't care'' license. Content may be freely distributed without attribution for all purposes. 

+  \item[CC BY] (Creative Commons Attribution License) -- this license lets others distribute, remix, adapt, and build upon your work, even commercially, as long as they credit you for the original creation.

-Creative Commons provides a range of licenses\footnote{Creative Commons License Chooser -- \url{https://creativecommons.org/choose/}}, each of which grants different rights to use the materials licensed under them. All of these licenses offer more permissions than ``all rights reserved''. Some of Creative Commons are free and some are non-free.
