Hi Jesus,
nice slick code there using regexp ;) just wondering if there would be a 
possibility of having a different set of file exceptions for different 
file paths. cause at the moment, there can only be one specific file 
exceptions for every file path, which might be hard in the event where 
we would need to cater to different source paths. Prolly a few arrays in 
file exception?
