+dit(bf(--chmod)) This options tells rsync to apply the listed "chmod" pattern
+to the permission of the files on the destination. In addition to the normal
+parsing rules specified in the chmod manpage, you can specify an item that
+should only apply to a directory by prefixing it with a 'D', or specify an
+item that should only apply to a file by prefixing it with a 'F'. For example:
+
+quote(--chmod=Dg+s,ug+w,Fo-w,+X)
