Below my sig is a 45 line program using Node.rb that converts the file into 
Node objects, each with a name and value. You can see how Walker objects and 
callback routines work. In order to output your chosen format (which I didn't 
completely understand), you'd need to create probably a couple more Walkers 
and a couple more callback routines.

This program assumes consistent indentation. If that cannot be assumed, you 
need to either do something else (maybe what Bill Guindon suggested), or 
create a tiny brace to indent converter and then run the result through my 
program.
