// 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

//   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.

  // 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 :

  // 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

  // Description :

  //   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 :

  //   PCLZIP_OPT_REMOVE_ALL_PATH :

  //   PCLZIP_OPT_COMMENT :

  //   PCLZIP_CB_PRE_ADD :

  //   PCLZIP_CB_POST_ADD :

  // Return Values :

  //   0 on failure,

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

  //   (see PclZip::listContent() for list entry format)

  //   The properties of each entries in the list are (used also in other functions) :

  //     filename : Name of the file. For a create or add action it is the filename

  //                given by the user. For an extract function it is the filename

  //                of the extracted file.

  //     stored_filename : Name of the file / directory stored in the archive.

  //     size : Size of the stored file.

  //     compressed_size : Size of the file's data compressed in the archive

  //                       (without the headers overhead)

  //     mtime : Last known modification date of the file (UNIX timestamp)

  //     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)

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

  //                                  write protected

  //                newer_exist : the file was not extracted because a newer file exists

  //                path_creation_fail : the file is not extracted because the folder

  //                write_error : the file was not extracted because there was a

  //                              error while writing the file

  //                read_error : the file was not extracted because there was a error
