Hi David,

I develop on LLVM and a number of subprojects using git.  The mirror
is one way so I don't think it would work to push there even if
you had access.  I use the git mirror primarily as a fast means of
fetching the latest commits, but for committing I use git-svn.

First I initialised git-svn:

git svn init https://llvm.org/svn/llvm-project/llvm/trunk
git update-ref refs/remotes/git-svn earl/master
  # "earl" is my remote for git://github.com/earl/llvm-mirror.git
git svn fetch

This is what I do to prepare to commit:

git fetch earl
git update-ref refs/remotes/git-svn earl/master
git svn fetch # this will fetch any commits less than an hour old
git rebase git-svn

Then I use "git svn dcommit" to commit.  You can probably script some
of this if you like.

Hope that helps.

Thanks,
