My SourceGraph programme (available on Hackage) can do this with a few
caveats:
1) Only supports functions, not data constructors, types, etc.
2) The project must be Cabalized
3) The functions exported must not be available from the library (though if it's
an executable, then it will return all non-called functions that aren't called
"main").

Those restrictions should fit my case very well. I have a .cabal file, I'm mainly interested in functions, and it's just an executable not a library.

This is basically what SourceGraph does.

Note that it hasn't been upgraded to GHC-6.10 yet, nor the HSE-4 series.

I don't think that will be a problem. I still haven't upgraded to 6.10 due to it uninstalling 6.8 (has anyone fixed this on osx yet?). And we don't use view patterns so HSE-4 is hopefully not needed.

Thanks,
Jason
