  //   created. Use create() for that.

  // Function :

  //   create($p_filelist, $p_option, $p_option_value, ...)
  // 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.
  // Options :
  //   PCLZIP_OPT_ADD_PATH :
  //   PCLZIP_OPT_REMOVE_PATH :
  //   PCLZIP_OPT_REMOVE_ALL_PATH :
  //   PCLZIP_OPT_COMMENT :
  //   PCLZIP_CB_PRE_ADD :
  //   PCLZIP_CB_POST_ADD :
  // Return Values :
  //   0 on failure,
  //   The list of the added files, with a status of the add action.
  //   (see PclZip::listContent() for list entry format)

  // Parameters :

  //              extract. The form of the string is "0,4-6,8-12" with only numbers
  //              and '-' for range or ',' to separate ranges. No spaces or ';'
  //              are allowed.
  //   $p_path : Path where the files and directories are to be extracted
  //   $p_remove_path : First part ('root' part) of the memorized path
  //                    (if any similar) to remove while extracting.
  // Options :
  //   PCLZIP_OPT_PATH :
  //   PCLZIP_OPT_ADD_PATH :
  //   PCLZIP_OPT_REMOVE_PATH :
  //   PCLZIP_OPT_REMOVE_ALL_PATH :
