  // Description :
  //   This method supports two different synopsis. The first one is historical.
  //   This method creates a Zip Archive. The Zip file is created in the
  //   filesystem. The files and directories indicated in $p_filelist
  //   are added in the archive. See the parameters description for the
  //   supported format of $p_filelist.
  //   When a directory is in the list, the directory and its content is added
  //   in the archive.
  //   In this synopsis, the function takes an optional variable list of
  //   options. See bellow the supported options.
  // Parameters :
  //   $p_filelist : An array containing file or directory names, or
  //                 a string containing one filename or one directory name, or
  //                 a string containing a list of filenames and/or directory
  //                 names separated by spaces.
  //   $p_add_dir : A path to add before the real path of the archived file,
  //                in order to have it memorized in the archive.
  //   $p_remove_dir : A path to remove from the real path of the file to archive,
  //                   in order to have a shorter path memorized in the archive.
  //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
  //                   is removed first, before $p_add_dir is added.

  //     stored_filename : Name of the file / directory stored in the archive.
  //     size : Size of the stored file.

  //                       (without the headers overhead)
  //     mtime : Last known modification date of the file (UNIX timestamp)
  //     comment : Comment associated with the file

  //     index : index of the file in the archive
  //     status : status of the action (depending of the action) :
  //              Values are :
