     155Many of the libraries in a GHC tree are actually maintained by someone else. They therefore have a separate upstream repository, from which we need to pull. That repository may be either a darcs or a git repository; in the darcs case, we also need to convert to a git repository for use in a GHC tree. This diagram shows how changes migrate from one repo to another:

     159This means that when making changes needed in GHC to one of these libraries, we first need to put the changes in the upstream repository. For example, to make a change to Cabal:
     160
     161 * First push the change as a darcs patch to the upstream Cabal repository, http://code.haskell.org/Cabal/
     162 * The patch will be mirrored and converted to git by the mirror script, in the repo http://darcs.haskell.org/git-mirrors/Cabal/.git/
     163 * You then need to pull from http://darcs.haskell.org/git-mirrors/Cabal/.git/ into `libraries/Cabal` in a regular GHC tree, validate, and push to the GHC Cabal repo, http://darcs.haskell.org/packages/Cabal.git/
