1w6 - Ein Würfel System - Einfach saubere, freie Rollenspiel-Regeln
This is an additional permission for the GPL. We call it the “just-link” permission.
As additional permission under GNU GPL version 3 section 7, you may distribute these works without the copy of the GNU GPL normally required by section 4, provided you include a license notice and a URL through which recipients can access the Corresponding Source and the copy of the GNU GPL.
Explanation: As long as you only use material which provides this permission in addition to being licensed under the GNU GPL, you can ship a printed book, a postcard or similar works without having to include a full copy of the GNU GPL. Material which uses this permission is compatible with any other work under GPL, but the permission only applies to the combined work if all parts carry it individually.
