3 * PhpConcept Library - Zip Module 2.5

5 * Presentation :
6 * PclZip is a PHP library that manage ZIP archives.
7 * So far tests show that archives generated by PclZip are readable by
8 * WinZip application and other tools.
9 *

11 * This library and the associated files are non commercial, non professional
12 * work.
13 * It should not have unexpected results. However if any damage is caused by
14 * this software the author can not be responsible.
15 * The use of this software is at the risk of the user.

35 * File list separator
36 *
37 * In version 1.x of PclZip, the separator for file list is a space(which is not
38 * a very smart choice, specifically for windows paths !). A better separator
39 * should be a comma (,). This constant gives you the abilty to change that.
40 *
41 * However notice that changing this value, may have impact on existing scripts,
42 * using space separated filenames. Recommanded values for compatibility with
43 * older versions :
44 * <code>define( 'PCLZIP_SEPARATOR', ' ' );</code>
45 * Recommanded values for smart separation of filenames.
