jQuery API XML - how is it maintained?

jQuery API XML - how is it maintained?

Hi guys,

I've looked at the VSDOC generator which uses  http://api.jquery.com/api/, wihich returns a big XML document for the API documentation. I'm wondering , how is this maintained? How do you ensure it is in sync with the source code? Whenever something changes in the code, does someone have to manually edit this XML? 

Thank you
