- * 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
