I didn't really look at the script, but I made a similar parser [1]  
earlier, initially for AUR2 purposes. Looking over it, it seems I  
don't include the file list during parsing, but that can probably be  
easily added in. Perhaps it can be expanded upon, instead of creating  
a new one. If not it should at least help.
