Module Dependencies

Each module should be self sufficient and not expect or rely on another module to be present. If such interaction is required (and sometimes it does make sense), then the module should be clearly identified as being dependent on the other module. If the situation does arise, it should be determined whether the functionality is best represented in distinct modules or whether the two modules that are dependent on each other are better represented in one encompassing module. The basic premise is to keep items together where it makes sense and not to create lots of smaller modules just for the sake of it.
