Module page doesn't describe what the module actually does

Yeah, I was thinking this too. What does the module do? I've used SASS, but I'm still not sure. I assume the module gives you a button to push to run SASS in your theme folder to rebuild your CSS? Or something like that? I'll probably download the source and look inside to see what it does, but it'd be great to have an explanation.

Aha, it gives you the option to automatically rebuild your Sass files on every page load... nice!
