<?PHP // $Id$

// This file is not used by Moodle itself.
//
// It exists to provide a more object-oriented interface to some of 
// Moodle's main library functions, for use by external programs.
// 
// Thanks to Greg Barnett from Crown College for ideas and code

// Usage example (from an external program):
// 
// /// Set things up
//     $external_moodle_access = true;                   // Affects setup.php
//     require_once("moodle/lib/makeclass.php");         // This file
//     makeClassFromFile("moodlelib.php", "moodlelib");  // File in $CFG->libdir
//
// /// Call moodle functions like this
//     moodle::isteacher($courseID); 


require_once("../config.php");
