checkout to ~/.config/git and adapt user-settings:
git clone git://github.com/gimpf/dotgit ~/.config/git
cp ~/.config/git/config-user-local.template ~/.config/git/config-user-local
${EDITOR:-vim} ~/.config/git/config-user-local
Doesn't do much except for setting up two pretty-formats, some aliases, and use of kdiff3.
