How to automatically format (indent) code written in any language

Question

Many a times, all I need to do is to indent some weird code badly or not indented at all. If I want to make it readable, I need proper indentation. One way to do this is to paste it in Eclipse and use ctrl+shift+F. But it's overkill. And eclipse takes a while to open up.

Is there a lightweight tool to do this?
