Ask HN: Is there a WGET that also works with paginated articles

I'd like to pull down a few articles from some news sites to store on my computer.

The problem is that many of these articles have pagination in them, so I only get the first page. Or they have that thing where you read a little bit, then have to click a button to make the rest of the text slide out.

I'm fairly new to linux. Is there a command-line utility or a program somewhere that will let me point it at a web page and it will get the page and all the sub-pages associated with it?
