//
// 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
// ability to change that.
// However notice that changing this value, may have impact on existing
// scripts, using space separated filenames.
// Recommended values for compatibility with older versions :
//define( 'PCLZIP_SEPARATOR', ' ' );
// Recommended values for smart separation of filenames.

// you must ensure that you have included PclError library.

// By default temporary files are generated in the script current

// ----- 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 algorithm is looking for
// memory_limit of PHP and apply a ratio.
// threshold = memory_limit * ratio.
// Recommended values are under 0.5. Default 0.47.

// When a directory is in the list, the directory and its content is added
// in the archive.

// options. See below the supported options.
// Parameters :
// $p_filelist : An array containing file or directory names, or
// a string containing one filename or one directory name, or
// a string containing a list of filenames and/or directory
// 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
// is removed first, before $p_add_dir is added.

// status : status of the action (depending of the action) :
// Values are :
// ok : OK !
// filtered : the file / dir is not extracted (filtered by user)
// already_a_directory : the file can not be extracted because a

// write_protected : the file can not be extracted because a file
