* @short_description: Abstract class representing the Control Center shell
26
* CcShell is an abstract class that represents an instance of a control
27
* center shell. It provides access to some of the properties of the shell
28
* that panels will need to read or change. When a panel is created it has an
29
* instance of CcShell available that represents the current shell.
