Very nice project! However, it looks like the user needs to explicitly
specify the paths to the sources. I have some code to perform a similar
task[1]; the paths are actually contained inside the bytecode.
I think that for native-code you can fetch them in a similar way, though
it is a little harder to extract the debug info.
