Haskell is a pure functional language. The Debian Haskell Group (DHG for friends!) is the team committed to packaging and maintaining a working and up-to-date Haskell environment and library in Debian.
Upstream references
http://www.haskell.org/ -- Haskell main web site
http://www.haskell.org/cabal/ -- Cabal (Common Architecture for Building Applications and Libraries), a program used to distribute many Haskell packages. Importing in Debian cabalized Haskell packages is quite an easy task, because most of the packaging and metadata writing work is already done. This is why we accept in Debian nearly only Cabal packages (nearly all Haskell packages are cabalized, though, so that's not a very restrictive decision).

Team infrastructure
Alioth Project: http://alioth.debian.org/projects/pkg-haskell -- to contribute to the DHG, register on Alioth and then use this link to ask for project membership; of course, you also need to subscribe to the mailing lists
Package Entropy Tracker: http://pkg-haskell.alioth.debian.org/cgi-bin/pet.cgi -- this PET only shows packages that are team-maintained using darcs
Dependency tree of our packages: http://pkg-haskell.alioth.debian.org/haskell-pkg-graph.pdf -- updated only manually; colors indicate installability

?/CollabMaint/PackageTemplate -- template for the package of a simple library.
All team-maintained packages are kept under some VCS (Version Control System). The most preferred is darcs (which is itself written in Haskell), other use git. Darcs has the advantage of being integrated with the Package Entropy Tracker, which makes it easier to check how things are going with Haskell package.
If you're using darcs:

If you're using git:
?/CollabMaint/GitBasic -- Use Git to check out code and submit commits
?/CollabMaint/GitPackaging -- instructions for using git-buildpackage to build from source
?/CollabMaint/GitCreation -- create new git repositories
TODO list
A raw list of things to do, hoping that somedays someone will start working on them...
- Fix policy, which is very old
- Adapt it to the current best-practises and haskell-devscripts workflow
Description guidelines, see for example http://lists.debian.org/4C2FA27F.50303@poisson.phc.unipi.it
- Fix wiki pages, which are very old too (some examples are completely deprecated)
- Create some Lintian test specific for Haskell packages
- Include --datasubdir=$(DEB_CABAL_PACKAGE) in hlibrary.mk
Libraries worth packaging: ?/PackageTODO

?GHC is now being team maintained
Out-of-date things
This list is kept for historical interest. If you're interested how thing (should) go now, you're in the wrong place.
