flash - Creating loading messages with swfobject -

I am loading a flash file via swfobject. As the file is large, I want to show the message "Wait until it loads" when the flash loads.

How can I do this with swfobject? You can use a small preloader SWF that triggers the loading-please-waiting animation.

And then loads the real SWF in the background There are many free preloaders on the web.
