Plugin to interact with the Google Translate API.
You'll need a Google Cloud active project and a set of credentials to use this plugin:
1. Create a project on the `Google Cloud console <https://console.cloud.google.com/projectcreate>`_ if
you don't have one already.
2. In the menu navigate to the _Artificial Intelligence_ section and select _Translations_ and enable the API.
3. From the menu select _APIs & Services_ and create a service account. You can leave role and permissions
empty.
4. Create a new private JSON key for the service account and download it. By default platypush will look for the
credentials file under ~/.credentials/platypush/google/translate.json.
Requires:
* **google-cloud-translate** (``pip install google-cloud-translate``)
