Initial setup
=============
Then we want to clone the repository. We normally want to have both

mkdir ~/emacs
cd ~/emacs
-git clone <membername>@git.sv.gnu.org:/srv/git/emacs.git
-mv emacs trunk

-./trunk/admin/git-new-workdir trunk emacs-24
-cd emacs-24
-git checkout emacs-24

You now have both branches conveniently accessible, and you can do
"git pull" in them once in a while to keep updated.

changes. Then you need to push the data to the main repository. This
will usually fail, since somebody else has pushed other changes in the
meantime. To fix this, say
git push

+you commit your change locally and then send a patch file as a bug report
