Revision:	1.14
Committed:	Sun Jul 1 05:00:21 2007 UTC (16 years, 11 months ago) by root
Content type:	text/plain
Branch:	MAIN
Changes since 1.13:	+11 -12 lines
Log Message:	- upgrade crossfire trt to the GPL version 3 (hopefully correctly). - add a single file covered by the GNU Affero General Public License (which is not yet released, so I used the current draft, which is legally a bit wavy, but its likely better than nothing as it expresses direct intent by the authors, and we can upgrade as soon as it has been released). * this should ensure availability of source code for the server at least and hopefully also archetypes and maps even when modified versions are not being distributed, in accordance of section 13 of the agplv3.
