""" A study, how to create plac annotated command line script from bare function
preserving original function intact.

This is sometime needed, when the same function is used for call e.g. by a celery, 
and for manual testing it is handy to have it in command line version.

Usually, the code (producing only annotated command line tool) looks like::

    import plac

vlcinsky

"""
Usage:
    csv2sql.py [--table <tablename>] <csvfile>

Options:
    --table <tablename>  Name of table in database to import into [default: mytable]

Convert csv file with iperf data into sql script for importing
those data into MySQL database.
