9 // Presentation :
10 // PclZip is a PHP library that manage ZIP archives.
11 // So far tests show that archives generated by PclZip are readable by
12 // WinZip application and other tools.
13 //
14 // Description :
15 // See readme.txt and http://www.phpconcept.net
16 //
17 // Warning :
18 // This library and the associated files are non commercial, non professional
19 // work.
20 // It should not have unexpected results. However if any damage is caused by
21 // this software the author can not be responsible.
22 // The use of this software is at the risk of the user.

31 // ----- File list separator
32 // In version 1.x of PclZip, the separator for file list is a space
33 // (which is not a very smart choice, specifically for windows paths !).
34 // A better separator should be a comma (,). This constant gives you the
35 // abilty to change that.
36 // However notice that changing this value, may have impact on existing
37 // scripts, using space separated filenames.
38 // Recommanded values for compatibility with older versions :

44 // 0 : PclZip Class integrated error handling
