"""
Usage: python get_gdrive_credentials.py PATH_TO_SECRET_FILE

The purpose of this script is to create google login credentials to be used by google drive
writer.

Expected workflow is:

1.- Get the client secret file. If you haven't one, please follow this tutorial:
https://developers.google.com/drive/web/quickstart/python

2.- Execute this script. It will open a browser tab in which you have to login with your
Google account. It will create a credentials file (file path will be printed).

3.- You can use the info contained in both files to configure a export using google
drive writer.
