+
+Recompile `.scss` files automatically for connect and express based http servers
+
+    var server = connect.createServer(
+      sass.middleware({
+          src: __dirname
+        , dest: __dirname + '/public'
+        , debug: true
+      }),
+      connect.static(__dirname + '/public')
+    );
