"""
There are two ways to use this script:
1. Pass a tag name as a single argument.
It will then take the clusters corresponding to that tag, and assign one
domain name per cluster. Currently it gets the domains from a hard-coded
path. There should be more domains than clusters.
Example: ./map-dns.py 2020-08-15-jp
2. Pass a domain as the 1st argument, and IP addresses then.
It will configure the domain with the listed IP addresses.
Example: ./map-dns.py open-duck.site 1.2.3.4 2.3.4.5 3.4.5.6
In both cases, the domains should be configured to use GANDI LiveDNS.
