@Inject
public void initializeAtStartup(final IWorkbench workbench, final ICommandService commandService) {
	/*
	 * Check the UI state of the IHandler/Command which indicates if the user
	 * enabled automatic PlusCal conversion.
	 */
	final Command command = commandService.getCommand("toolbox.command.module.translate.automatially");
	final State state = command.getState(RegistryToggleState.STATE_ID);
	if (!((Boolean) state.getValue()).booleanValue()) {
		return;
	}
	// This IHander is stateful even across Toolbox restarts. In other words, if the
	// user enables automatic PlusCal translation, it will remain enabled even after
	// a Toolbox restart. This means we have to register this EventHandler at the
	// IEventBroker during Toolbox startup.
	// It is vital that we use the Workbench's IEventBroker instance. If e.g. we
	// would use an IEventBroker from higher up the IEclipseContext hierarchy, the
	// broker would be disposed when a new spec gets opened while the IHandler's state
	// remains enabled.
	workbench.getService(IEventBroker.class).unsubscribe(this);
	Assert.isTrue(workbench.getService(IEventBroker.class).subscribe(TLAEditor.PRE_SAVE_EVENT, this));
