+TODO:
+
+ - This patch needs to be rewritten to more efficiently handle large xattrs.
+
+ - We need to affect the itemized output to know when xattrs are being updated.
+
+ - We need to affect the --link-dest option to avoid hard-linking two files
+ that differ in their xattrs (when --xattrs was specified).
