// 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.
