i've filled in the section on provides/requires with what i remember from our discussion.
Thanks. I quite like the idea of inferring in much more detail what a package actually needs from its imports. Having Cabal do the module dependency analysis will make this a bit easier, but doing it at a finer granularity than the module list will require more complicated language processing. I suppose there is the question of how much should be in the language (like ML functors) and how much in the packaging system. Duncan
