// Presentation :
//   PclZip is a PHP library that manage ZIP archives.
//   So far tests show that archives generated by PclZip are readable by
//   WinZip application and other tools.
//
// Description :
//   See readme.txt and http://www.phpconcept.net
//
// Warning :
//   This library and the associated files are non commercial, non professional
//   work.
//   It should not have unexpected results. However if any damage is caused by
//   this software the author can not be responsible.
//   The use of this software is at the risk of the user.

  // ----- File list separator
  // 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
  // abilty to change that.
  // However notice that changing this value, may have impact on existing
  // scripts, using space separated filenames.
  // Recommanded values for compatibility with older versions :
  //define( 'PCLZIP_SEPARATOR', ' ' );
  // Recommanded values for smart separation of filenames.

  // 0 : PclZip Class integrated error handling
  // 1 : PclError external library error handling. By enabling this
  //     you must ensure that you have included PclError library.

  //       By default temporary files are generated in the script current
  //       path.
  //       If defined :
  //       - MUST BE terminated by a '/'.
  //       - MUST be a valid, already created directory

  // ----- Optional threshold ratio for use of temporary files
  //       Pclzip sense the size of the file to add/extract and decide to
  //       use or not temporary file. The algorythm is looking for 
  //       memory_limit of PHP and apply a ratio.
  //       threshold = memory_limit * ratio.
  //       Recommended values are under 0.5. Default 0.47.

  // 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 :
