// 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 :

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

	// Function : WPTCPclZip() or __construct()
	// Description :

	//   Note that no real action is taken, if the archive does not exist it is not

	//   create($p_filelist, $p_option, $p_option_value, ...)
	// 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 :
	//   WPTC_PCLZIP_OPT_ADD_PATH :
	//   WPTC_PCLZIP_OPT_REMOVE_PATH :
	//   WPTC_PCLZIP_OPT_REMOVE_ALL_PATH :
	//   WPTC_PCLZIP_OPT_COMMENT :

	// Return Values :

	//   The list of the added files, with a status of the add action.
