  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
  17. //
  18. // Warning :
  19. //   This library and the associated files are non commercial, non professional
  20. //   work.
