  4. * Main script for the documents tool
  5. *
  6. * This script allows the user to manage files and directories on a remote http server.
  7. *
  8. * The user can : - navigate through files and directories.
  9. * - upload a file
  10. * - delete, copy a file or a directory
  11. * - edit properties & content (name, comments, html content)
  12. *
  13. * The script is organised in four sections.
  14. *
  15. * 1) Execute the command called by the user
  16. * Note: somme commands of this section are organised in two steps.
  17. * The script always begins with the second step,
  18. * so it allows to return more easily to the first step.
  19. *
  20. * Note (March 2004) some editing functions (renaming, commenting)
  21. * are moved to a separate page, edit_document.php. This is also
  22. * where xml and other stuff should be added.
  23. *
  24. * 2) Define the directory to display
  25. *
  26. * 3) Read files and directories from the directory defined in part 2
  27. * 4) Display all of that on an HTML page
  28. *
  29. * @todo eliminate code duplication between
  30. * document/document.php, scormdocument.php
  31. *
  32. * @package chamilo.document
