What is behavior: url(); property in css?

I was surfing and saw this css property which I have never seen or used before. I think it is related to Internet Explorer, and the structure is something like this:

#element{
  behavior: url(something.htc);
}

What does the behavior property do? How would I use this property?

I did find this w3 Documentation, but it's not particularly clear what it does.

It lets you use CSS to attach a script to a specific element in order to implement DHTML (Dynamic HTML) components.

Internet Explorer versions 5 and later support the behavior property. Internet Explorer 8 supports Vendor specific format of -ms-behavior
