  // Function : PclTarHandleAddList()
  // Description :
  //	$p_add_dir and $p_remove_dir will give the ability to memorize a path which is
  //	different from the real path of the file. This is usefull if you want to have PclTar
  //	running in any directory, and memorize relative path from an other directory.
  // Parameters :
  //	$p_tar : File descriptor of the tar archive
  //	$p_list : An array containing the file or directory names to add in the tar
  //	$p_mode : "tar" for normal tar archive, "tgz" for gzipped tar archive
  //	$p_list_detail : list of added files with their properties (specially the status field)
  //	$p_add_dir : Path to add in the filename path archived
  //	$p_remove_dir : Path to remove in the filename path archived
  // Return Values :
