/**
* Homepage 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 with document/document.php, scormdocument.php
*
* @package chamilo.document
