-  // 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 :

-  // Description :
-  //   This method supports two synopsis. The first one is historical.
-  //   This methods add the list of files in an existing archive.
-  //   If a file with the same name already exists, it is added at the end of the
-  //   archive, the first one is still present.

-  //   $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

-  //   properties.
-  //   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 !
