+	* doc/conf/conf.xml: Added configuration section for writing mapfiles.
+
+	* src/main/java/de/intevation/gnv/utils/MapfileGenerator.java: Singleton 
+	  generator for writing mapfiles. It runs in an own thread and has an 
+	  'update' method which triggers the generator to search the filesystem for 
+	  shapefiles and meta information and update mapfiles out of these 
+	  information. A 'main' method can be invoked to update the mapfile without
+	  an running artifact server.
+
+	  TODO: Implement method stubs.
+
+	* src/main/java/de/intevation/gnv/state/profile/horizontalcrosssection/HorizontalCrossSectionMeshOutputState.java:
+	  Call MapfileGenerator when writing or removing shapefiles (endOfLife).
