Code: All references in the code not related to themes, keybindings, or GConf were changed from 'metacity' to 'mutter'. This includes, among other things, strings, comments, the atoms used in the message protocol, and the envvars used for debugging. The GConf schema file was reduced to the 3 settings new to mutter. The overall version was brought up to 2.27 to match current gnome. Structure: All files named '*metacity*' were renamed '*mutter*' with appropriate changes in the automake system. Files removed are doc/creating_themes, src/themes, doc/metacity-theme.dtd, metacity.doap. These files will eventually end up in an external gnome-wm-data module. Installation location: On the filesystem the mutter-plugindir was change from $(libdir)/metacity/plugins/clutter to just $(libdir)/mutter/plugins. The mutter-plugins.pc.in reflects these changes. Note: mutter.desktop.in and mutter-wm.desktop both continue to have X-GNOME-WMSettingsModule=metacity set. This allows gnome-control-center to continue using libmetacity.so for configuration. This is fine since most the general keybindings and wm settings are being read from /apps/metacity/* in gconf.
