+Subject: [patch] Add `--link-by-hash' option (rev 5).
+Date: Mon, 23 Feb 2004 13:29:08 -0500
+
+This patch adds the --link-by-hash=DIR option, which hard links received
+files in a link farm arranged by MD4 file hash.  The result is that the system
+will only store one copy of the unique contents of each file, regardless of
+the file's name.
+
+(rev 5)
+* Fixed silly logic error.
+
+(rev 4)
+* Updated for committed robust_rename() patch, other changes in CVS.
+
+(rev 3)
+* Don't link empty files.
+* Roll over to new file when filesystem maximum link count is reached.
+* If link fails for another reason, leave non-linked file there.
+* Depends on rsync-rename.diff
+
+(rev 2)
+* This revision is actually against CVS HEAD (I didn't realize I was working
+  from a stale rsync'd CVS).
+* Apply permissions after linking (permissions were lost if we already had
+  a copy of the file in the link farm).
