Within a set of modules, the minimal imports also give you the minimal
exports since each minimal export is required because it is imported
somewhere. Just compile all your modules with -ddump-minimal-imports,
then cat all your "*.import" files together and sort the result. The
minimal exports for module Foo will be listed as several lines of the
form "import Foo(x,y,z)", etc. From there on it's just a bit of text
munging to get it into your export list code (about two lines of
perl).

Alright, that's the same manual process I do now. I didn't use -ddump-minimal-imports before because I didn't know about it and we maintain sufficiently minimal imports already. That and I used emacs macros instead of perl because I already know how to use emacs :)

If I take the time to automate this I wonder if it's a worthwhile tool to upload to hackage. Sounds like others have been doing this sort of thing.

Now if I just had a round touit...

Thanks everyone!
