/**
 * Site archive interface.
 * Site archive is a representation of a packaged archive (file) located
 * on an update site. It allows a "symbolic" path used to identify
 * a plug-in or non-plug-in feature entry to be explicitly mapped
 * to a specific URL. 
 * <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.ArchiveReference
 * @since 2.0
 * @deprecated The org.eclipse.update component has been replaced by Equinox p2. This
 * provisional API was never promoted to stable API, and may be removed from a future release of the platform.
