Re: GPL v3 survey site

Jerry James writes: We can change the permissions to a subset of the licenses we received. Eg, we could do something like "GPLv2 or later, provided that the major version is *even* and the minor version is 1 or greater." (Speaking of silly....) In particular, we can stop distributing under GPLv2 (and must if we wish to sync FSF code, since they no longer grant GPLv2 licenses, and so those won't be in the set of licenses we receive from them). The point is that "GPL, v2 or later" is not a single license, it is a *set* of licenses, each of which individually gives us permission to redistribute under that license and that license only. Ie, to state that extensionally, GPLv2 is in "GPL, v2 or later", so we have a GPLv2 license, and we can grant that license to our downstream. GPLv3 is also in "GPL, v2 or later", so we have and can grant that one, too, or not, as we please. We can do either or both, but until GPLv4 is published, we can't distribute unless we choose one of GPLv2 or GPLv3, since XEmacs contains code licensed to us only under "GPL, v2 or later". We can't use a license that is not in the intersection of all copyleft licenses we have received for code in our derivative work. If that intersection is empty, we can't distribute. More silliness: we could, in theory, distribute under "GPL, v4 or later", but since that hasn't been published yet, nobody can do anything but run XEmacs with it (according to the FSF theory that running a program is not regulated by copyright). _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
