+  I think that would be good too.  For example, people uploading files   
+  to a web server might like to say
+
+  rsync -avzP --chmod a+rX ./ sourcefrog.net:/home/www/sourcefrog/
+
+  Ideally the patch would implement as many of the gnu chmod semantics
+  as possible.  I think the mode parser should be a separate function
+  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
