"""Simple command-line sample for Google Maps Engine.

This sample code demonstrates use of the Google Maps Engine API. For more

information on the API, see developers.google.com/maps-engine/documentation/

These samples allow you to

1) List projects you have access to

2) List tables in a given project.

3) Upload a shapefile to create a Table asset.

Usage:

$ python maps_engine.py [-p project_id] [-s shapefile]

If you do not enter a shapefile, it will upload the included "polygons".

You can also get help on all the command-line flags the program understands

by running:

$ python maps_engine.py --help

To get detailed log output run:

$ python maps_engine.py -p 123456 --logging_level=DEBUG
