      Before you can use these tools you must export a variable to your $SHELL.
        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.
