Does anyone know how to write a Ruby script that would convert a csv file to a json file?

The CSV would be in this format:

Canon,Digital IXUS 70,"Epic, Epic 100",3x,Yes (lockable),Yes (lockable),Yes
Canon, Digital IXUS 75,"Epic, Epic 100",3x,Yes (lockable),Yes (lockable),Yes
Canon,Digital IXUS 80,"Epic, Epic 100",3x,Yes (lockable),Yes (lockable),Yes

and the JSON would need to result in this:

{ "aaData": [
[ "Canon" , "Digital IXUS 70" , "3x" , "Yes (lockable)" , "Yes (lockable)" , "Yes"],
[ "Canon" , "Digital IXUS 75" , "3x" , "Yes (lockable)" , "Yes (lockable)" , "Yes"],
[ "Canon" , "Digital IXUS 80" , "3x" , "Yes (lockable)" , "Yes (lockable)" , "Yes"]
]}
