+## Move Media
+
+Aggregate media queries and move it to the end of the file.
+
+### API
+
+    var moveMedia = require('move-media')
+
+    var css = rework(inputCSS)
+      .use(moveMedia(sortFunction))
+      .toString()
+
+By default, `sortFunction` just sorts the queries alphabetically:
+
+    function sortFunction(a, b) {
+      if (a < b) return 1;
+      if (a > b) return -1;
+      return 0
+    }
+
+### Limitations
+
+- Assumes media query order does not matter.
+  If it does, then use your own sort function.
+- Declarations within each media query preserves order.
+- In general, keep the order in mind!
