/**
 * Site content provider.
 * A site content provider is an abstraction of each site internal 
 * organization. It allows the site content to be accessed in
 * a standard way regardless of the internal organization. All concrete site
 * implementations need to implement a site content provider.
 * <p>
 * Clients may implement this interface. However, in most cases clients should 
 * directly instantiate or subclass the provided implementation of this 
 * interface.
 * </p>
 * <p>
 * <b>Note:</b> This class/interface is part of an interim API that is still under development and expected to
 * change significantly before reaching stability. It is being made available at this early stage to solicit feedback
 * from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
 * (repeatedly) as the API evolves.
 * </p>
 * @see org.eclipse.update.core.SiteContentProvider
 * @since 2.0
 * @deprecated The org.eclipse.update component has been replaced by Equinox p2.
 * This API will be deleted in a future release. See bug 311590 for details.
