animating a rope being wound on a spool

I am trying to figure out how to animate winding a rope on a reel or spool. I found one web site from searching this site that looks like what I am trying do, but the site no longer exists. I am using curves and the curve modifier in my attempts. I want to take a fixed length of rope and wind it on a spool like one would do by hand.

You can use a chain of objects that are connected via constraints. Search for tutorials on creating a rigid-body chain, and that will get you started.
