yamldiff.php

<?php
/**
 * This script is a CLI tool for quickly comparing an online yaml file with a local file
 * 
 * @param string $url - the URL value for the location of an online YAML file
 * @param string $file - the full path of a local YAML file e.g. MezaCoreExtensions.yml
 * 
 * You could easily just do the same thing with diff, wdiff, sdiff
 * Or, using a GUI with Kompare, Meld, DiffMerge, diffuse, KDiff3
