9// Presentation :
10//   PclZip is a PHP library that manage ZIP archives.
11//   So far tests show that archives generated by PclZip are readable by
12//   WinZip application and other tools.
13//

15//   See readme.txt and http://www.phpconcept.net

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

215  //   filesystem. The files and directories indicated in $p_filelist

221  //   options. See bellow the supported options.

223  //   $p_filelist : An array containing file or directory names, or
224  //                 a string containing one filename or one directory name, or
225  //                 a string containing a list of filenames and/or directory
226  //                 names separated by spaces.
227  //   $p_add_dir : A path to add before the real path of the archived file,
228  //                in order to have it memorized in the archive.
229  //   $p_remove_dir : A path to remove from the real path of the file to archive,
230  //                   in order to have a shorter path memorized in the archive.
231  //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
