// 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

//   work.

  // ----- Constants
  define( 'PCLZIP_READ_BLOCK_SIZE', 2048 );
  
  // ----- 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.
  define( 'PCLZIP_SEPARATOR', ',' );

  // ----- Error configuration
  // 0 : PclZip Class integrated error handling
  // 1 : PclError external library error handling. By enabling this
  //     you must ensure that you have included PclError library.
  // [2,...] : reserved for futur use

  // ----- Optional static temporary directory
  //       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

  //   create() : Creates the Zip archive
  //   listContent() : List the content of the Zip archive
  //   extract() : Extract the content of the archive

  //   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.

  //                of the extracted file.
  //     stored_filename : Name of the file / directory stored in the archive.
  //     size : Size of the stored file.
  //     compressed_size : Size of the file's data compressed in the archive
  //                       (without the headers overhead)
  //     mtime : Last known modification date of the file (UNIX timestamp)
  //     comment : Comment associated with the file
  //     folder : true | false
  //     index : index of the file in the archive
  //     status : status of the action (depending of the action) :
  //              Values are :
