Summary of the effect of the submodule changes

Hi all,

This is just a quick summary of the effect of the move to submodules:


If you are only making changes to the GHC repository, or to other
repositories for which we use the main repository directly (including
all the libraries that we maintain), then you don't need to do anything
different. Just continue to commit as normal, and use "./sync-all pull"
and "./sync-all push" as before. The list of repositories that this
applied to is given near the top of
    http://hackage.haskell.org/trac/ghc/wiki/WorkingConventions/Repositories


However, if you need to make changes to any of the repositories in the
list below, then you will need to read the "From the GHC developer's
point of view" section of
    http://hackage.haskell.org/trac/ghc/wiki/WorkingConventions/Repositories
for details of what now needs to be done.
Repository list:
    * libraries/binary
    * libraries/bytestring
    * libraries/Cabal
    * libraries/containers
    * libraries/haskeline
    * libraries/pretty
    * libraries/terminfo
    * libraries/transformers
    * libraries/xhtml
    * libraries/Win32
    * libraries/primitive
    * libraries/vector


Thanks
Ian
