JSON parser/generator for GNUstep?

[Jens Alfke]

What are people using for their JSON needs in GNUstep? The code I’m porting 
uses NSJSONSerialization, but this is new in Lion/iOS5 and doesn’t exist in the 
base framework yet.

I’ve tried building both JSONKit and json-framework, but both of them have a 
bunch of CFString code in them. I could start hacking at that code to convert 
it to NSString (if possible), but I’m wondering if someone else has already 
done something like this?
