I have an event from my input like this:  
{  
"Name" =\> "A",  
"Description" =\> "B"  
}

I need to convert it to JSON for my output, but the event should be a sub node in the JSON - I want it to end up like so:

{  
"event": {  
"Name": "A",  
"Description": "B"  
}  
}

To make it slightly more complicated, the fields in the event may be different. (There may not always be a description field, and sometimes there may be a different field in there)

Is there a simple (or even not so simple) way to achieve this?
