// 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

// 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', ' ');

//             Pclzip sense the size of the file to add/extract and decide to

//             memory_limit of PHP and apply a ratio.
//             threshold = memory_limit * ratio.
//             Recommended values are under 0.5. Default 0.47.

//     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

		// Description :
		//     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.
		//     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.
		// Options :
		//     PCLZIP_OPT_ADD_PATH :
		//     PCLZIP_OPT_REMOVE_PATH :
		//     PCLZIP_OPT_REMOVE_ALL_PATH :
		//     PCLZIP_OPT_COMMENT :
