* You will also need to configure which callback class to call. This you do
* with the ezcBaseInit::setCallback() method. The following examples sets the
* callback classname for the configuration identifier
* 'ConfigurationManagerConfig' to 'cfgConfigurationManager':
*
*
*
*
*
* The class 'cfgConfigurationManager' is required to implement the
* ezcBaseConfigurationInitializer interface, which defines only one method:
* configureObject(). An example on how to implement such a class could be:
*
*
* init( 'ezcConfigurationIniReader', 'settings', array( 'useComments' => true ) );
* }
* }
* ?>
*
*
* Ofcourse the implementation of this callback class is up to the application
* developer that uses the component (in this example the Configuration
* component's class ezcConfigurationManager).
