Migrating patches from darcs to git

Suppose ghc/darcs is a darcs GHC tree containing patches that need to be migrated to git, and ghc/git is a git GHC tree. We're not going to try to preserve the history; just get the code into the repo.

This assumes that all your changes are in the ghc repo itself. Otherwise, if you have made changes to other repos (e.g. libraries/base) you'll need to do a similar procedure for those repos too.

First, make a backup of the darcs repo in case something goes wrong:

cp -a ghc/darcs ghc/backup-darcs

Now make sure ghc/darcs is fully up-to-date:

cd ghc/darcs
./darcs-all pull -a

Next we checkout the git repo as it was at the darcs branch point:
