At the beginning of this thread, someone posted a link to the Sage worksheet:
http://abstract.ups.edu/sage-aata.html That is 1) being publicly distributed and 2) is not being released under the GPL. Plus, anyone can create an account on the public Sage notebook servers, so basically any worksheet that is Shared there falls under this category. Finally a quick Google for "Sage Worksheet" or ".sws" reveals *many* public Sage worksheets, and at a glance, none of them have any licensing information. Now that I think about it, how would I release a worksheet under the GPL. The usual way is to add: This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version....etc. to the source. Is there a simple way of doing that? Would it make sense to enable notebook users to add this to their Worksheet by simply clicking a box "Make this GPL." Then, when a Worksheet is loaded, if it has the GPL text, the notebook could display it or notify the user "This Worksheet is GPLd."
