      Before you can use these tools you must export some variables to your $SHELL.
        export AWS_ACCESS_KEY="<Your AWS Access ID>"
        export AWS_SECRET_KEY="<Your AWS Secret Key>"
        export AWS_CREDENTIAL_FILE="<Path to the credentials file>"

      To check that your setup works properly, run the following command:
        rds-describe-db-instances --headers
      You should see a header line. If you have database instances already configured,
      you will see a description line for each database instance.
