      River is a dynamic tiling Wayland compositor with flexible runtime
      configuration.

      Its design goals are:
      - Simple and predictable behavior, river should be easy to use and have a
        low cognitive load.
      - Window management based on a stack of views and tags.
      - Dynamic layouts generated by external, user-written executables. A
        default rivertile layout generator is provided.
      - Scriptable configuration and control through a custom Wayland protocol
        and separate riverctl binary implementing it.
