+Description
+-----------
+
+This patch centers dmenu in the middle of the screen.
+
+Previously this has been achieved through the [xyw patch][1] and a bash script
+to calculate the centered x and y positions. However, this is a slow and overly
+complex way which is hard to integrate into programs which call dmenu directly,
+eg surf or tabbed. On the other hand, This small standalone patch is
+instantaneous and works globally.
