Repo init user and email

[Colin Godsey]

I'm trying to semi-automate the process of using repo. When I call
repo init from this script, it works fine, but it doesnt ask for name
and email. Where is this info stored, and is there a way to set this
over command line?

git config --global user.name "A U Thor"
git config --global user.email y...@example.com
