What is a selector engine?

I've seen news of John Resig's fast new selector engine named Sizzle pop up in quite a few places, but I don't know what a selector engine is, nor have any of the articles given an explanation of what it is. I know Resig is the creator of jQuery, and that Sizzle is something in Javascript, but beyond that I don't know what it is. So, what is a selector engine?

I agree with:

A selector engine is used to find elements in a document, in the same way as CSS stylesheets does. Currently only Safari has the built-in querySelectorAll function which does just that. With other browser you have to use external JavaScript implementations as LlamaLab Selector or Sizzle instead.
