The easiest way to achieve the imports/dependencies is to parse the 
output of `dmd -v file1.d file2.d', and grep for "^semantic <fileX>" + 
following "^import".. just take a look yourself, I'm sure it's easier 
than using the frontend itself.

Apart from that, how does the Xcode build process work? Can't you just 
call a binary from inside Xcode?
