I was torn for a long time over whether to license under the GPL or
AGPL. I've settled on the GPL as I think it'd be quite hard to enforce
the AGPL (because of the nature of the RuneScape private server
community), and honest people would be at a disadvantage compared to
people who would ignore the additional provisions of the AGPL.
The *-natives modules are licensed under the LGPL as they are intended
to be linked with the proprietary client software, so the GPL would not
be appropriate.
I've decided to use v3 (and only v3) of the GPL. I don't like the 'or
later' clause as it means placing a great deal of trust in the FSF not
to change the overall intention of the license in future versions.
