Mutter
lightweight GTK+ window manager
Mutter is a small window manager, using GTK+ and Clutter to do
everything.
Mutter is the clutter-based evolution of Metacity, which, as the
author says, is a "Boring window manager for the adult in you. Many
window managers are like Marshmallow Froot Loops; Metacity is like
Cheerios."
This package contains the core binaries.
