| 10 | client_secret.json file to obtain an OAUTH token (json data) and \ | ||
| 11 | store it next to the source .json for future use. \n\n\ | ||
| 12 | To acomplish this, you will be given an URL that you can follow to \ | ||
| 13 | get a "code" which can then be used to get a token. As an I/O solution \ | ||
| 14 | I run this script with `node --inspect-brk` and then I catch the debugger \ | ||
| 15 | after the URL is logged to the console. Once I have the code, I can run \ | ||
| 16 | `code="{codeFromUrl}"` and resume the script. \n\n\n'; | ||
