Here's a stupid question, but it didn't show up in the docs so far...

What's a pager?

I'm guessing that it's the "Previous Next" links at the top of a page to browse many, many comments.

But, I don't really understand the comment in pager.inc:

pager_query
- Use this function when doing select queries you wish to be able to page.

I see pager_blah used a lot in the modules, without truly knowing what they are or what it does, so any clarification would be appreciated!

Thank you!
