// 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.

// 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.
