+Subject: [PATCH] Add deck-layout
+
+deck is a dwm-layout which is inspired by the TTWM window manager.
+It applies the monocle-layout to the clients in the stack.
+The master-client is still visible. The stacked clients are like
+a deck of cards, hence the name.
+
+The vanilla patch doesn't work properly with patches which add gaps.
+This means that when the deck-layout is activated gaps are omitted.
+To make it work with the tilegap-patch apply the dwm-deck-tilegap patch
+on top of the dwm-deck patch.
+
+The vanilla patch doesn't respect the master-area which is defined by
+the rmaster-patch. To make it work with the rmaster-patch apply the
+dwm-deck-rmaster patch on top of the dwm-deck patch.
