+	* src/main/java/de/intevation/flys/client/server/MapPrintServiceImpl.java:
+	  Generate legen via getlegendgraphic of the layers. Does not
+	  look too pretty right now.
+
+	* src/main/webapp/WEB-INF/config.yaml: Added legend block. We need
+	  to learn how the layout really work to make it look pretty.
