[Haskell-beginners] modules

So I created the following directory structure: home /MusDoc/MusDoc.hs home /MusDoc/FromXML.hs home /MusDoc/Timing.hs home /Midi/FromMusDoc.hs I set -i to "home" referred to above, so I import these modules with commands like import MusDoc.MusDoc import Midi.FromMusDoc etc.. What do I do to import everything in MusDoc via import MusDoc ? I suspect this has something to do with packages... don't feel a need to explain it all---point me to a good explanation and I'll probably figure it out. Mike
