usage_description="
Run a command against each Cloudflare zone

All arguments become the command template

The command template replaces the following for convenience in each iteration:

{id}   - with the zone id   <-- this is the one you want for chaining API queries with cloudflare_api.sh
{name} - with the zone name

eg.
    ${0##*/} 'echo zone id = {id} and name = {name}'
"
