//
// 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.

  // ----- Error configuration

  // you must ensure that you have included PclError library.

  // 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
