How to draw scrolling background?

How do I make a scrolling background in Flash 8 that follows an object controlled by the mouse?

• If you don't get what I mean, I'm talking about something like the background in this game; http://www.kongregate.com/games/Pacthesis/chrono-days-sim-date (To find what I'm talking about, click "skip intro" at the beginning of the game, then click "leave" twice to go outside).

  What's happening here is that the background's X position is being dynamically controlled based on the position of the mouse within the window (I'm sure you already knew that). The closer the object is to one side or the other, the slower the background scrolls until it reaches the extreme edge. The actionscript would go something like this (likely needs debugging to get it to work): onEnterframe() { var mouseXpos = _root._xmouse; var bg_width = bg_movieClip._width; var stage_width = stage.width; var bgPosRatio =mouseXpos/stage_width; bgMovieClipInstnceName._x = bgPosRatio*(bg_width - stage_width); } This doesn't give it the speed/up slow down effect but will scroll across the background movie clip at a constant rate.
