/*
Usage:
node sort.js {arguments}
`arguments` is one or more file paths, separated by spaces.

The script updates each file by sorting the labels by their keys.

If no arguments are passed, all language files will be sorted.

Example:
node sort.js languages/de-DE/assess-api.json languages/de-DE/questions-api.json
node sort.js
