Steven Maude:

Can be an issue on boxes, where it's not really ideal to set these in .gitconfig and if the user doesn't pass through their current environment settings.

A solution might be to check if these variables are already set and, if not, prompt the user for a name and email, then set them in the current environment:

export GIT_AUTHOR_EMAIL="some@mail.com"
export GIT_AUTHOR_NAME="Some Name"
export GIT_COMMITTER_EMAIL=${GIT_AUTHOR_EMAIL}
export GIT_COMMITTER_NAME=${GIT_AUTHOR_NAME}

(I do this manually to workaround my non-standard git config.)
