+  //   $p_filelist : An array containing file or directory names, or
+  //                 a string containing one filename or one directory name, or
+  //                 a string containing a list of filenames and/or directory
+  //                 names separated by spaces.
+  //   $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.
+  //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
+  //                   is removed first, before $p_add_dir is added.
