- * causes the application to be launched on the given screen
- * %EGG_DESKTOP_FILE_LAUNCH_WORKSPACE: (int workspace)
- * causes the application to be launched on the given 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
- * egg_desktop_file_accepts_multiple() returns %FALSE for
- * @desktop_file, then egg_desktop_file_launch() will actually launch
- * multiple instances of the application. In that case, the return

- *
