Will force symlink config files. Use with care...
./setup
I have excluded my name and email from this config. I recommend that you add them via system instead:
git config --system user.name "John Doe"
git config --system user.email "john.doe@example.com"
Run to install:
ln -s dotfiles/.git-templates ~
git config --global init.templatedir '~/.git-templates'
Do git init to copy in existing repos
