+To apply the recorded changes to another destination tree, run rsync
+with the read-batch option, specifying the name of the same batch
+file, and the destination tree. Rsync updates the destination tree
+using the information stored in the batch file.
+
+For your convenience, a script file is also created when the write-batch
+option is used: it will be named the same as the batch file with ".sh"
+appended. This script file contains a command-line suitable for updating a
+destination tree using the associated batch file. It can be executed using
+a Bourne (or Bourne-like) shell, optionally passing in an alternate
+destination tree pathname which is then used instead of the original
+destination path. This is useful when the destination tree path on the
+current host differs from the one used to create the batch file.
