| * The <code>ConfigurationManager</code> is the central class in this |
| * implementation of the Configuration Admin Service Specification. As such it |
| * has the following tasks: |
| * <ul> |
| * <li>It is a <code>BundleActivator</code> which is called when the bundle |
| * is started and stopped. |
| * <li>It is a <code>BundleListener</code> which gets informed when the |
| * states of bundles change. Mostly this is needed to unbind any bound |
| * configuration in case a bundle is uninstalled. |
| * <li>It is a <code>ServiceListener</code> which gets informed when |
| * <code>ManagedService</code> and <code>ManagedServiceFactory</code> |
| * services are registered and unregistered. This is used to provide |
| * configuration to these services. As a service listener it also listens for |
| * {@link PersistenceManager} instances being registered to support different |
| * configuration persistence layers. |
| * <li>A {@link ConfigurationAdminFactory} instance is registered as the |
| * <code>ConfigurationAdmin</code> service. |
| * <li>A {@link FilePersistenceManager} instance is registered as a default |
| * {@link PersistenceManager}. |
| * <li>Last but not least this instance manages all tasks laid out in the |
| * specification such as maintaining configuration, taking care of configuration |
| * events, etc. |
| * </ul> |
| * <p> |
| * The default {@link FilePersistenceManager} is configured with a configuration |
| * location taken from the <code>felix.cm.dir</code> framework property. If |
| * this property is not set the <code>config</code> directory in the current |
| * working directory as specified in the <code>user.dir</code> system property |
| * is used. |
