/**
 * The {@link CocoaUIHandler} provides the standard "About", "Preferences...",
 * and "Quit" menu items and links them to the corresponding workbench commands.
 * This must be done in a MacOS X fragment because SWT doesn't provide an
 * abstraction for the (MacOS X only) application menu and we have to use MacOS
 * specific natives. The fragment is for the
 * org.eclipse.e4.ui.workbench.renderers.swt plug-in because we need access to
 * the Workbench "About", "Preferences...", and "Quit" actions.
 * 
 * @noreference this class is not intended to be referenced by any client.
