You're right, let's talk about "derivative works". Let's consider the following simplified, but very common and typical scenario: Say, I have programmed one PHP script (myApp.php), which calls another PHP script (gplSort.php) in order to sort some values in a database. I put myApp.php and my COPYING.txt and gplSort.php and the GPLv3.txt in a ZIP file and sell it on USB sticks as SuperMineTM. Central questions: A) Is SuperMineTM a derivative work of gplSort.php? B) Is SuperMineTM a bundle of two software packages "myApp" and "gplSort"? Case A: myApp.php would have to be (when released to the public) under the same (GPL) license as gplSort.php. Case B: If myApp.php is considered to be a work independent from gplSort.php - then the choice of licence is up to me. I see that there are many people who are uncertain about such cases, and possibly there are many people with different opinions on what is the legal situation. Maybe it would be a nice idea, if we (FSF/E) would develop a case-by-case guide for software developers to help them with these things. Does something like that exist? Maybe in the FAQs? It would be a pity, if developers choose to not use (A/L)GPL, only out of confusion! Cheers, Jann -- PS: The above is a thought experiment to illustrate a common situation. Personally, I would solve that problem by releasing SuperMineTM (if it existed) under the GPL, of course! ;)
