+=item B<BATCH>
+
+This command initiates the bulk load of multiple commands.  This is
+designed for installations with extremely high update rates, since it
+permits more than one command to be issued per read() and write().
+
+All commands are executed just as they would be if given individually,
+except for output to the user.  Messages indicating success are
+suppressed, and error messages are delayed until the client is finished.
+
+Command processing is finished when the client sends a dot (".") on its
+own line.  After the client has finished, the server responds with an
+error count and the list of error messages (if any).  Each error messages
+indicates the number of the command to which it corresponds, and the error
+message itself.  The first user command after B<BATCH> is command number one.
