This sample was created for a talk for Google Cloud NEXT'18 entitled "Building

on the Docs Editors: APIs and Apps Script". It is the implementation of a

commandline tool that:

* Extracts template variables out of a Google Slides template presentation

* Writes those variables to a Google Sheets spreadsheet

* Adds data to the spreadsheet based on those variables from a stub data service

* Generates new Google Slides presentations using the template and the

spreadsheet data

* Follow the [Sheets API python quickstart](https://developers.google.com/sheets/api/quickstart/python)

* Make sure to save the client-secrets.json in your working directory

* In the developer project you created, also enable the Google Slides API and

the Google Drive API

* Run the tool:

<pre>

// Create the spreadsheet from the Google Slides template

$ python qbr_tool.py create_sheet --template_id &lt;your template id&gt;

// Add data from the stub customer service

$ python qbr_tool.py add_customers \

--spreadsheet_id &lt;your spreadsheet id&gt; \

--customer_id jupiter

// Generate the filled in presentation

$ python qbr_tool.py create_presentations

--spreadsheet_id &lt;your spreadsheet id&gt; \

--customer_id jupiter

</pre>
