Haskell Packages 6.6?

Hello good Haskell Hackers.

We're pretty well along the way to getting cabal-install and friends
working nicely.  We've got almost 30 packages in the database.

Let's imagine something that would be awesome.  A set of Haskell
packages which are all known to work together with a particular
version of cabal (the one that GHC comes with), and a particular
version of GHC.

GHC version 6.6 will be released soon, and I think we should try to
make this happen.

Currently, we have a set of 27 "unstable" packages.  They may or may
not work with each-other and such:


I just created an empty directory "testing".  I propose that we start
testing packages, starting with the cabal release candidate that'll go
into GHC 6.6, and make sure they work nicely together.  Once they're
known to work, we can migrate them from the "unstable" directory to
the "testing" directory.

Once we have a sufficient collection of packages, and once ghc 6.6 is
released, we can make a snapshot of this directory, call it
"stable-6.6" or something.  Then if you have ghc 6.6 and
cabal-install, you should be able to "cabal-install p" for any
package, and it'll definitely work.

So what will we need for this to happen?

1. An installed version of ghc 6.6 on the hackage/darcs server.  Maybe
   in a chroot or something.  Maybe from the nightly build tree or the
   previous snapshot?

2. Some initial set of packages (maybe just cabal-install) to start

3. Some script that goes through and builds all of the "unstable"
   packages in dependency order.  I think cabal-install can do this
   already.  In fact, it would be ideal if we used cabal-install for

4. The script should also run ./setup haddock and ./setup test.  If
   the packages seem to work w/ 6.6 and the other packages in
   "testing", it should get migrated from "unstable" to "testing".

5. A web interface (lemmih is working on it)

6. A script to upload packages to "unstable" (Paolo is working on it).

7. Someone to spearhead all of this!
