2041    Map of search patterns to permission masks. If a directory name matches
2042    one of the patterns, that directory and all its members and subdirectories
2043    will be assigned the new pattern. For example, the following would
2044    assign 01664 to most files, but would use 01777 for directories named C<tmp>.
2045    
2046        Tracer::SetPermissions($dirName, 'fig', 01664, '^tmp$' => 01777);
2047    
2048    The list is ordered, so the following would use 0777 for C<tmp1> and
2049    0666 for C<tmp>, C<tmp2>, or C<tmp3>.

2053    
2054    Note that the pattern matches are all case-insensitive, and only directory
2055    names are matched, not file names.
