use Hadrian to see if compiler compiles?

I'm currently doing some refactoring of the GHC sources, which involves moving definitions between modules. As a sanity check I want to compile often, so if I've broken anything (or have inadvertently created circular imports) I can find out quickly. I'm currently using ./hadrian/build -j but I really don't need to build libraries or a stage 2 compiler. I tried looking over `./hadrian/build --help`, but I'm not confident that I understand what's there. My best guess is ./hadrian/build -j stage0:lib:ghc Would that accomplish my goal? Norman
