// 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
//
// 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 :
//define('PCLZIP_SEPARATOR', ' ');
// Recommanded values for smart separation of filenames.
if (!defined('PCLZIP_SEPARATOR')) {
    define('PCLZIP_SEPARATOR', ',');

// ----- Error configuration
// 0 : PclZip Class integrated error handling
// 1 : PclError external library error handling. By enabling this
//         you must ensure that you have included PclError library.
// [2,...] : reserved for futur use

// ----- Optional static temporary directory
//             By default temporary files are generated in the script current
//             path.
//             If defined :
//             - MUST BE terminated by a '/'.
//             - MUST be a valid, already created directory
//             Samples :

// ----- Optional threshold ratio for use of temporary files
//             Pclzip sense the size of the file to add/extract and decide to
//             use or not temporary file. The algorythm is looking for
//             memory_limit of PHP and apply a ratio.
//             threshold = memory_limit * ratio.
//             Recommended values are under 0.5. Default 0.47.

//     create() : Creates the Zip archive
//     listContent() : List the content of the Zip archive
//     extract() : Extract the content of the archive

    //     This method supports two different synopsis. The first one is historical.
    //     This method creates a Zip Archive. The Zip file is created in the
    //     filesystem. The files and directories indicated in $p_filelist
    //     are added in the archive. See the parameters description for the
    //     supported format of $p_filelist.

    //     in the archive.
    //     In this synopsis, the function takes an optional variable list of
    //     options. See bellow the supported options.

    //     $p_filelist : An array containing file or directory names, or
    //                                 a string containing one filename or one directory name, or

    //                                 names separated by spaces.
    //     $p_add_dir : A path to add before the real path of the archived file,
    //                                in order to have it memorized in the archive.
    //     $p_remove_dir : A path to remove from the real path of the file to archive,
    //                                     in order to have a shorter path memorized in the archive.
    //                                     When $p_add_dir and $p_remove_dir are set, $p_remove_dir
