For Creative Commons licenses, you can get a nice, neat summary in the form of Creative Commons Deeds (which I linked to in the announcement post):
7
* Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Deed, for resources (i.e., non-source code files).
8
* Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Deed, for previous releases (back to and including 1.39).

There is no official equivalent for the GPL, which is a more complicated license with a big baggage of politics. However, the Creative Commons project has a similar Deed summarising the GPL.

The general intent of all the licenses used for Oolite now and in the past is that you may modify it, in whole or in part, as long as you don’t claim to have created it; however, you must distribute any modifications you make under the same terms. As of the transition to the GPL, you may also sell it (but not attempt to restrict your customers from redistributing it) – although Messrs. B&B may have ideas about that.

Expressing licenses in terms of what you can do without touching on what you can’t do is inherently intractable, because managing restrictions on what you’re permitted to do is what licensing is all about.

- later versions of the game will be GPL only for the game and gpl/cc-nc-sa for the data; as a consequence, the copyright file needs clen-up
