   Welcome to issue 162 of the HWN, a newsletter covering developments in
   the [1]Haskell community in the week of December 05 - 11.

   Wouter Swierstra [2]sent a call for papers for the ICFP 2011 to be held
   in Tokyo, Japan between September 19 - 21. The announcement contains
   all relevant dates of importance

   Dmitry Astapov [3]announced the realease of haskell-mpi, "a suite of
   Haskell bindings to the C MPI [Message Passing Interface] and
   convenience APIs on top of it."

   David Waern [4]annouced a new version of the venerable Haddock. "This
   version is compatible with .haddock files produced by the version of
   Haddock that comes with GHC 7.0.1."

   Michael Snoyman [5]announced the first release of his library and
   executable packdeps. "This is a library and executable containing the
   same functionality as the original packdeps website, namely letting you
   know when your version bounds exclude the use of the newest version of
   a library available."

   Michael also [6]announced the second major release of the mime-mail
   library. This "is a package providing support for rendering multipart

   Jasper Van der Jeugt [7]announced the release of the digestive
   functors library. "The library provides a general API to input
   consumption, and is an upgrade of formlets."

   So, what went on this week?
