+      A layout generator for **river**. Features include:
+      - **configurable** layouts employing nested tiles (no juggling with coordinates),
+      - **widescreen** support by default,
+      - default layouts, switchable at run time with a command or key binding:
+          - dwm-like main/stack layout,
+              - main on the left on normal screens,
+              - **main in the center and stacks on both sides** on widescreens,
+          - a vertical stack,
+          - a horizontal stack, and
+          - a monocle layout,
+      - optional per-tag-per-output state.
