// 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.

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

//       If defined :
//       - MUST BE terminated by a '/'.
//       - MUST be a valid, already created directory

// ----- 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.

// Class : PclZip
// Description :
//   PclZip is the class that represent a Zip archive.
//   The public methods allow the manipulation of the archive.
// Attributes :
//   Attributes must not be accessed directly.
// Methods :
//   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

	// Function : PclZip()
	// Description :
	//   Creates a PclZip object and set the name of the associated Zip archive
	//   filename.
	//   Note that no real action is taken, if the archive does not exist it is not
	//   created. Use create() for that.

	// 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 :
