[javascript] Javascript: How to generate formatted easy-to-read JSON straight from an object?

How can I beautify JSON programmatically?

I know how to generate JSON from an object using JSON.stringify, or in my case the handy jquery-json from google code (https://github.com/krinkle/jquery-json).

Now this works fine, but the output is hard to read for humans. Is there an easy way / function / whatever to output a neatly formatted json file?

This is what I mean:

JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}); 

gives..

"{"a":1,"b":2,"c":{"d":1,"e":[1,2]}}"

I'd like something like this instead:

{
 "a":1,
 "b":2,
 "c":{
    "d":1,
    "e":[1,2]
 }
}

E.g. with newlines and tabs added. It's much easier to read for larger documents.

I'd like to do this ideally without adding any huge libraries - e.g. not prototype or YUI or whatever.
