[la le]

does anyone know of a objective c parser?, 
i need to extract all the info from @interface
declarations (class name, class super, varibale names,
if they are protected/priveate/public, method names
and its variables), and also from @implementation
declareations i need to extract method names and its
argument names, along with the raw text in the
methods. .... 
then i need to be able to save them to file.

anyone know of a starting point to get the info i need?
