Derived from sblaisot/certbot-dns-01-authenticators

This fork fixes a few issues we met for our use-case:

• compatibility with python 2 for use with the certbot/certbot Docker image
• works with multiple domains (e.g. base domain AND wildcard subdomains)

Example usage

docker run -it --rm \
    --name certbot \
    --volume /etc/letsencrypt:/etc/letsencrypt \
    --volume /var/lib/letsencrypt:/var/lib/letsencrypt \
    --volume "$(pwd)/gandi-livedns:/gandi-livedns" \
  certbot/certbot certonly \
    --manual \
    --manual-auth-hook /gandi-livedns/auth.py \
    --manual-cleanup-hook /gandi-livedns/cleanup.py \
    --domains example.com,*.example.com

or see certbot.sh which is a (work in progress) wrapper.
