-This adds a sender optimization feature that allows a cache of checksums
-to be used when the client specifies the --checksum option, and creates
-and/or updates the .rsyncsums files when --checksum-updating is
-specified.
+This builds on the sender optimization feature of the checksum-reading
+patch and adds the ability to create and/or updates the .rsyncsums files
+when --checksum-updating (or "checksum updating = true") is specified.
To use this patch, run these commands for a successful build:
+ patch -p1 <patches/checksum-reading.diff
patch -p1 <patches/checksum-updating.diff
