10// Presentation :
11//   PclZip is a PHP library that manage ZIP archives.
12//   So far tests show that archives generated by PclZip are readable by
13//   WinZip application and other tools.
14//
15// Description :
16//   See readme.txt and http://www.phpconcept.net

33// ----- File list separator
34// In version 1.x of PclZip, the separator for file list is a space
35// (which is not a very smart choice, specifically for windows paths !).
36// A better separator should be a comma (,). This constant gives you the
37// abilty to change that.
38// However notice that changing this value, may have impact on existing
39// scripts, using space separated filenames.

71//       use or not temporary file. The algorythm is looking for
72//       memory_limit of PHP and apply a ratio.
73//       threshold = memory_limit * ratio.
74//       Recommended values are under 0.5. Default 0.47.

249    //                 a string containing one filename or one directory name, or

251    //                 names separated by spaces.
252    //   $p_add_dir : A path to add before the real path of the archived file,
253    //                in order to have it memorized in the archive.
254    //   $p_remove_dir : A path to remove from the real path of the file to archive,
255    //                   in order to have a shorter path memorized in the archive.
256    //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
