-and Google Sheets.  It accepts the following command line arguments:
-
---push table_name or all
-
---pull worksheet_name or all
 
-Either --push or --pull must be present and it must be one or the other.
-
---export on or off

-separated tables the tables being pushed or worksheets being pulled with 
-timestamps.
