This is a snippet from bootstrap.php which acts as an auto loader based on scan dir.

bootstrap.php

<?php

// This will auto load the following and/or create files if needed.
//
// plugin/controllers/$post_type_controller.php
// plugin/models/$post_type.php
// plugin/assets/stylesheets/$post_type.php
// plugin/assets/javascripts/$post_type.php
//
// note as of now the oder of the files is not important, we'll cross
// that bridge when we get to it.

foreach( $tmp_controllers as $controller ) {
    /**
     * autoload Controllers
     */
    require_once CONTROLLERS_ROOT_DIR . $controller;

    // Return just the first part of our controller
    $name = array_shift( explode( '_', $controller ) );

    /**
     * Models
     */
    if ( file_exists( MODELS_ROOT_DIR . $name . '.php' ) )

    }
