Mutter is a window and compositing manager that displays and manages your
desktop via OpenGL. Mutter combines a sophisticated display engine using the
Clutter toolkit with solid window-management logic inherited from the Metacity
window manager.

While Mutter can be used stand-alone, it is primarily intended to be used as
the display core of a larger system such as GNOME Shell. For this reason,
Mutter is very extensible via plugins, which are used both to add fancy visual
effects and to rework the window management behaviors to meet the needs of the
environment.

This package contains an experimental Mutter version with Wayland support. It
will eventually get merged back into the main Mutter package and mutter-wayland
is going to go away; in the mean time this package is available for early
adopters.
