control-center bug fix and enhancement update

Updated control-center packages that fix one bug and add various enhancements
are now available for Red Hat Enterprise Linux 6.

The control-center packages contain various configuration utilities for the
GNOME desktop. These utilities allow the user to configure accessibility
options, desktop fonts, keyboard and mouse properties, sound setup, desktop
theme and background, user interface properties, screen resolution, and other
settings.

This update fixes the following bug:

* Previous versions of the control-center package contained gnome-at-mobility, a
script that requires a software component that is not distributed with Red Hat
Enterprise Linux 6 nor is present in any of the available channels. With this
update, the non-functional gnome-at-mobility script has been removed and is no
longer distributed as part of the control-center package. (BZ#771600)

As well, this update adds the following enhancements:

* The background configuration tool now uses the XDG Base Directory
Specification to determine where to store its data file. By default, this file
is located at ~/.config/gnome-control-center/backgrounds.xml. Users can change
the ~/.config/ prefix by setting the XDG_DATA_HOME environment variable, or set
the GNOMECC_USE_OLD_BG_PATH environment variable to 1 to restore the old
behavior and use the ~/.gnome2/backgrounds.xml file. (BZ#524942)

* The control-center-extra package now includes a GNOME Control Center shell.
This shell provides a user interface for launching the various Control Center
utilities. (BZ#632680)

* The GNOME Control Center now provides a configuration utility for Wacom
graphics tablets, which replaces the wacompl utility. (BZ#769465, BZ#801363)

All users of control-center are advised to upgrade to these updated packages,
which fix this bug and add these enhancements.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
