Building extra-libs using Cabal

[Simon Peyton-Jones]

The Haskell libraries are gradually moving towards being buildable using
Cabal, rather than by GHC's make system.  This is good.  But here are
two bug reports telling what doesn't work:

	http://hackage.haskell.org/trac/ghc/ticket/893
	http://hackage.haskell.org/trac/ghc/ticket/894

(missing Setup.hs, and/or Haddock parsing errors).  Ross has fixed some
of these (thanks!).

This message is to invite package maintainers to work on fix the
remaining glitches.  (We won't undertake to fix this for GHC 6.6,
because these packages can be upgraded separately.)  

The relevant packages are:

Haddock errors: http://hackage.haskell.org/trac/ghc/ticket/894
	network 
	xhtml 
	opengl 
	openal 
	alut

Missing Setup http://hackage.haskell.org/trac/ghc/ticket/893
	arrows 
	fgl 
	haskell-src 
	html 
	hunit 
	mtl 
	quickcheck 
	time


Thanks!
