usage_description="
Run a command against each GCP project in the current account

This is powerful so use carefully!

All arguments become the command template

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

{id}   - with the project id
{name} - with the project name

eg.
    ${0##*/} 'echo GCP project has id {id} and name {name}'
