+ * %EGG_DESKTOP_FILE_LAUNCH_WORKSPACE: (int workspace)

+ * %EGG_DESKTOP_FILE_LAUNCH_DIRECTORY: (char *dir)
+ * causes the application to be launched in the given directory
+ * %EGG_DESKTOP_FILE_LAUNCH_TIME: (guint32 launch_time)
+ * sets the "launch time" for the application. If the user
+ * interacts with another window after @launch_time but before
+ * the launched application creates its first window, the window
+ * manager may choose to not give focus to the new application.
+ * Passing 0 for @launch_time will explicitly request that the
+ * application not receive focus.
+ * %EGG_DESKTOP_FILE_LAUNCH_FLAGS (GSpawnFlags flags)
+ * Sets additional #GSpawnFlags to use. See g_spawn_async() for
+ * more details.
+ * %EGG_DESKTOP_FILE_LAUNCH_SETUP_FUNC (GSpawnChildSetupFunc, gpointer)
+ * Sets the child setup callback and the data to pass to it.
+ * (See g_spawn_async() for more details.)
+ *
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_PID (GPid **pid)
+ * On a successful launch, sets * pid to the PID of the launched
+ * application.
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_STARTUP_ID (char **startup_id)
+ * On a successful launch, sets * startup_id to the Startup
+ * Notification "startup id" of the launched application.
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_STDIN_PIPE (int *fd)
+ * On a successful launch, sets * fd to the file descriptor of
+ * a pipe connected to the application's stdin.
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_STDOUT_PIPE (int *fd)
+ * On a successful launch, sets * fd to the file descriptor of
+ * a pipe connected to the application's stdout.
+ * %EGG_DESKTOP_FILE_LAUNCH_RETURN_STDERR_PIPE (int *fd)
+ * On a successful launch, sets * fd to the file descriptor of
+ * a pipe connected to the application's stderr.
+ *
+ * The options should be terminated with a single %NULL.
+ *
+ * If @documents contains multiple documents, but
