How I organize groupsConfig.php in PHP Minify.

groupsConfig.php

<?php
/**
 * Groups configuration for default Minify implementation
 * @package Minify
 */

/** 
 * You may wish to use the Minify URI Builder app to suggest
 * changes. http://yourdomain/min/builder/
 **/

class grc {
    private $array;
    private $base;
    private $key;

    function k($k) {
        $this->key = $k;

        return $this;
    }

    function b($b) {
        $this->base = $b;

        return $this;
    }

    function a($a) {
        $this->array[$this->key][] = '//' . $this->base . $a;

        return $this;
    }

    function o($o) {
        $this->array[$this->key][] = '//' . $o;
        return $this;
    }

    function g() {
        return $this->array;
    }
}

$g = new grc();

$a = $g
    ->k('js')
        ->b('js/jquery/')
            ->a('jquery-1.3.2.js')
            ->a('jquery-dom.js')
            ->a('jquery.json-1.3.min.js')
