Example of new plugin format aimed for easy scripting.

MyPlugin.php

<?php

/**
 * This file is an example of a compressed plaintext plugin format for PocketMine
 * It's aimed towards easy scripting, but not for normal plugin development.
 * 
 * This kind of plugin won't be able to embed/load resources,
 * nor have access to some features like fast permission/command integration.
 * 
 * This first comment is used to define the properties like on plugin.yml,
 * having the same name but not being able to define complex types (arrays, multi-line strings)
 * 
 * @name MyPlugin
 * @main authorName\MyPlugin\MainClass
 * @version 1.0.0
 * @api 1.12.0
 * @description My super plugin
 * @author authorName
