Walter Landry seems to be arguing that the scope of section 2 is the entity who makes the changes + any copyrightable work distributed by that entity + running the program + apt sections. In other words, if you modify emacs so that it loads faster, and then you distribute emacs with some "patches only" licensed source code, then you'd be violating the GPL if that source code was in main, but not if that source code was in non-free. Except, I'm sure he'd argue that that doesn't matter because emacs isn't running the source code, it's only displaying it. Or perhaps he'd argue something else which tries to make notions of functionality a copyright issue. Anyways, to my mind the thing missing from your explanation (which was basically good) is that a little critical thinking needs to happen to identify the work being modified. Clearly, modification doesn't alter the permissions granted by the "mere aggregation" clause, because both are in section 2, with the "mere aggregation" clause being an addition to the modification rules. So there has to be some other reason -- besides modification -- for the components of some derived work to be considered as part of a work (a Program) which is more than mere aggregation. Here's how I'd phrase the criteria: If A and B are copyrightable modules of work C, where A is GPLed and B does not satisfy the terms of the GPL, then distribution is restricted by the GPL if B was specifically created to go with A. There are some edge cases where this way of expressing things doesn't work so well, but we don't seem to be discussing those kinds of things at the moment. Finally, it's worth noting that the permission to distribute unmodified copies only applies to the source. Another way of putting this is that binaries are always treated as modified copies. -- Raul -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
