24409 * Presentation :
24410 * PclZip is a PHP library that manage ZIP archives.
24411 * So far tests show that archives generated by PclZip are readable by
24412 * WinZip application and other tools.
24413 *
24414 * Warning :
24415 * This library and the associated files are non commercial, non professional
24416 * work.
24417 * It should not have unexpected results. However if any damage is caused by
24418 * this software the author can not be responsible.
24419 * The use of this software is at the risk of the user.
