+Take note of the GNU Affero General Public License (COPYING.Affero),
+which applies to part of this release, which means you have to follow the
+requirements laid out in section 13 of both licenses (see COPYING.GNU).
 
+As long as you follow the provisions of the APGL you should be safe.

+Note that ALL changes introduced by the Deliantra team are under the
+Affero General Public License. Specifically, the files listed below are
+100% AGPL. The listing of these files does not imply the remaining files
+do not contain any AGPL code (the opposite is actually true).
+
+The archetypes and maps are mostly GPL, but all maps and archetype file
+added by Deliantra are AGPL, unless otherwise noted (many media files are
+cc:by or similarly permissive, and this is noted in the META.json files in
+directories that have them). Again, note that unless you remove the AGPL
+parts, then the whole server, maps and archetypes distributions have to be
+treated according to the Affero GPL.
+
+Here is an algorithm to decide which parts of the server code are AGPL and
+which are not:
+
+1. is the file listed below (glob syntax)?
+   if yes, it is 100% AGPL.
+2. does the file contain //+GPL and/or //-GPL markers?
+   if yes, then everything is AGPL, except the code between
+   //+GPL and //-GPL.
+3. is the code listed in COPYING.Other?
+   if yes, see there
+4. otherwise, the code is 100% GPL.
