// PclZip is a PHP library that manage ZIP archives.

// $p_add_dir : A path to add before the real path of the archived file,

// in order to have it memorized in the archive.

// $p_remove_dir : A path to remove from the real path of the file to archive,
|

// in order to have a shorter path memorized in the archive.
