R licence

Duncan,

Letting you know then that I just don't see how the first paragraph here :

http://www.revolutionanalytics.com/downloads/gpl-sources.php

is compatible with clause 2(b) here :

http://www.gnu.org/licenses/gpl-2.0.html

Perhaps somebody could explain why it is?

As I understand it, they believe that it falls under the "mere aggregation" exception at the end of sec.2, and they believe that their plugins are not "derived works", but add-ons. The legal hair-splitting is rather painful...
