+// 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

+// 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

+ // abilty to change that.
+ // However notice that changing this value, may have impact on existing
