/**
 * Main script for the documents tool
 *
 * This script allows the user to manage files and directories on a remote http server.
 *
 * The user can : - navigate through files and directories.
 *				 - upload a file
 *				 - delete, copy a file or a directory
 *				 - edit properties & content (name, comments, html content)
 *
 * The script is organised in four sections.
 *
 * 1) Execute the command called by the user
 *				Note: somme commands of this section are organised in two steps.
 *				The script always begins with the second step,
 *				so it allows to return more easily to the first step.
 *
 *				Note (March 2004) some editing functions (renaming, commenting)
 *				are moved to a separate page, edit_document.php. This is also
 *				where xml and other stuff should be added.
 *
 * 2) Define the directory to display
 *
 * 3) Read files and directories from the directory defined in part 2
 * 4) Display all of that on an HTML page
 *
 * @todo eliminate code duplication between
 * document/document.php, scormdocument.php
 *
 * @package chamilo.document
