// 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.

// 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.

// PclZip() : Object creator
// create() : Creates the Zip archive
// listContent() : List the content of the Zip archive
// extract() : Extract the content of the archive
// properties() : List the properties of the archive

// When a directory is in the list, the directory and its content is added
// in the archive.
// In this synopsis, the function takes an optional variable list of
// options. See bellow 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.

// comment : Comment associated with the file
// folder : true | false
// index : index of the file in the archive
// 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
// directory with the same name already exists
// write_protected : the file can not be extracted because a file
// with the same name already exists and is
// write protected
// newer_exist : the file was not extracted because a newer file exists

// and '-' for range or ',' to separate ranges. No spaces or ';'
// are allowed.

// (if any similar) to remove while extracting.
