Review Comment:
   The `String, int` overload correctly handles the user passing a directory, 
which the `String[], int` overload does not (Each `String` needs to be a 
complete uri to a source). I'll look into whether I could handle both 
directories and complete URIs in the `String[], int` implementation, in which 
case we wouldn't need `String, int`.
