+  I think that would be good too.  For example, people uploading files   
+  to a web server might like to say

+  Ideally the patch would implement as many of the gnu chmod semantics

+  that passes back something like (mask,set) description to the rest of
+  the program.  For bonus points there would be a test case for the  
+  parser.
