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 //
14 // Description :
15 // See readme.txt and http://www.phpconcept.net
16 //
17 // Warning :
18 // This library and the associated files are non commercial, non professional
19 // work.
20 // It should not have unexpected results. However if any damage is caused by
21 // this software the author can not be responsible.

250 // a string containing one filename or one directory name, or
251 // a string containing a list of filenames and/or directory
252 // names separated by spaces.
253 // $p_add_dir : A path to add before the real path of the archived file,
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,
