With GHC, we can generate the dependencies using 'ghc -M' and then parse the generated Makefile. ... How would we do this with nhc98 or Hugs?

hmake -M Foo | tail +2 | cut -d' ' -f2

works independently of any compiler. If there are compiler-specific imports selected by cpp directives, then

hmake -hc=ghc-6.2.2 -M ...

We really should add depenency analysis to Cabal directly. The only reason to avoid this, afaik, is that parsing the imports might be a little tricky. I don't think that hmake necessarily handles every possible case here, semi-colons separating lines and multi-line comments, for instance (though maybe it does handle these, I might be wrong). It does a good job, and we can use that code in Cabal as well. FWIW, I'm working on code to add --with-haddock-args to configure, so no one else needs to worry about that right now. It's almost done. peace, isaac
