+                    	<li>Wind data in GRIB format can now be imported in the "Wind" sub-tab of the "Tracked Races" tab
+                    	    in the <tt>AdminConsole</tt>. When one or more races are being tracked, with a tracking time

+                    	    Multiple GRIB files can be specified; this is even necessary if GRIB sources are being used where
+                    	    the so-called "U" and "V" or "speed" and "direction" components, respectively, are provided in
+                    	    separate files. The importer will merge the GRIB sources to produce wind readings with true
+                    	    wind direction and true wind speed.
+                    	    Note that large GRIB files can result in many wind fixes being added to the WEB source. Make sure
+                    	    the GRIB files you use are adequate in resolution and region as well as adequate in time. Obtaining
+                    	    a forecast 72h in the future makes little sense for an in-shore race starting in 30min.
