Bringing up package relationships raises an interesting point.

If the generated docs don't work with different ghc versions then they
need to depend on the right ghc version, break the wrong version or ghc
needs to break them. I think the best would be a versioned provides
(when will they finally be usable?) like this:

Package: libghc6-zip-archive-doc
Provides: ghc6-docs (x.y)

Package: ghc6
Breaks: ghc6-docs (<< x.y), ghc6-docs (>> x.y)


But having some generated html files depend on the exact ghc version
seems extrem. So splitting out the version dependent .haddoc files into
the -dev packages (as mentioned in another mail in this thread) seems
the right, or at least the sanest, thing to do.

Am I right that with that split the -dev package depends on the right
ghc version (which is needs to anyway) while the -doc remains
independent? And with the -dev package being arch:any the whole issue of
arch:all binNMUs becomes mood?
