+2012-04-05  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/themes.xml: Defined a theme for WSPLGEN layers.
+
+	* src/main/java/de/intevation/flys/artifacts/model/MapserverStyle.java:
+	  Made style creation more robust against nullpointers and added an
+	  Expression class.
+
+	* src/main/java/de/intevation/flys/utils/ThemeUtil.java: Added a static
+	  method createWSPLGENStyle() and some helpers to create a WSPLGEN style.
+
+	* src/main/java/de/intevation/flys/exports/MapGenerator.java,
+	  src/main/java/de/intevation/flys/utils/MapfileGenerator.java: Methods
+	  for creating the WSPLGEN layer now take a style document.
