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

  254.   //                in order to have it memorized in the archive.
  255.   //   $p_remove_dir : A path to remove from the real path of the file to archive,
  256.   //                   in order to have a shorter path memorized in the archive.
