"""Simple program to demonstrate the Google+ Domains API.

This program shows how to authenticate an app for domain-wide delegation and how
to complete an activities.insert API call. For details on how to authenticate on
a per-user basis using OAuth 2.0, or for examples of other API calls, please see
the documentation at https://developers.google.com/+/domains/.

Changelog:
- 2017-12-29: 
--- Update authenticate() to use JSON credentials.
--- Remove SERVICE_ACCOUNT_EMAIL, as it's not necessary for JSON authentication.
--- Replace references to SERVICE_ACCOUNT_PKCS12_FILE_PATH with SERVICE_ACCOUNT_JSON_FILE_PATH, and update the associated path.
