+/* This algorithm is based on a (M)aster area and a (S)tacking area.
+ * It supports following arrangements:
+ *
+ * MMMS MMMM
+ * MMMS MMMM
+ * MMMS SSSS
+ *
+ * The stacking area can be set to arrange clients vertically or horizontally.
+ * Through inverting the algorithm it can be used to achieve following setup in
+ * a dual head environment (due to running two dwm instances concurrently on
+ * the specific screen):
+ *
+ * SMM MMS MMM MMM
+ * SMM MMS MMM MMM
+ * SMM MMS SSS SSS
+ *
+ * This uses the center of the two screens for master areas.
