Configuration is read from `digital_ocean.ini`, then from environment variables,
then and command-line arguments.
Most notably, the DigitalOcean Client ID and API Key must be specified. They
can be specified in the INI file or with the following environment variables:
export DO_CLIENT_ID='DO123' DO_API_KEY='abc123'
Most notably, the DigitalOcean API Token must be specified. It can be specified
in the INI file or with the following environment variables:
export DO_API_TOKEN='abc123' or
export DO_API_KEY='abc123'
Alternatively, they can be passed on the command-line with --client-id and

get them into your environment (e.g., to use the digital_ocean module)
