A simple script to paginate through all the direct replies to a tweet, uses "twurl" CLI tool

getTweetReplies.js

var fs = require('fs');
var exec = require('child_process').exec;

/**
	::NOTICE::
	Requires `twurl` to be installed -> https://github.com/twitter/twurl

	::Custom Parameters::
	filename
		name of the file to write to, defaults to replies_output.txt
	user
		user who is receving the replies
	since_id
		the ID of the tweet to get the replies from, should be a string since too large for int
	max_id
		the ID of the last tweet to get (newest tweet)
		leave empty to ignore (will be set during pagination)
	limit
		the number of times to paginate, good to keep low for testing due to API rate limits
		use 0 to ignore
