discord.js-docgen

This is the application that generates the docs.json files for discord.js and discord.js-commando.
It parses all JSDocs in any given directories, and outputs a single JSON file with data about all classes, properties, methods, typedefs, etc.
It also accepts custom docs files.
This is handy for documentation websites, so that they can load the data dynamically and display it however they need.
