+// 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 :
