  // In version 1.x of PclZip, the separator for file list is a space
  // (which is not a very smart choice, specifically for windows paths !).
  // A better separator should be a comma (,). This constant gives you the
  // ability to change that.
  // However notice that changing this value, may have impact on existing
  // scripts, using space separated filenames.
  // Recommended values for compatibility with older versions :
  //define( 'PCLZIP_SEPARATOR', ' ' );

  // 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 below 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 :
