-Tokens are character sequences which are treated as syntactic units within statements.
-
-Square brackets <code>[</code> and <code>]</code> enclose optional syntax.
-Three dots in a row <code>...</code> mean the preceding tokens may be repeated.
-A vertical bar <code>|</code> means the preceding and following tokens are mutually exclusive alternatives.

-Depending how one combines the tarantool client's options, there are in effect three modes of operation:
-<quote>interactive</quote>, <quote>print and play</quote>, or <quote>replication</quote> mode.
-</para>
-<para>
-In <emphasis>interactive</emphasis> mode, one types statements and gets results.
-One can specify a statement file when starting
-(<code>tarantool < file_name</code>)
-or one can specify a statement file with the LOADFILE statement:
-(<code>LOADFILE file_name</code>), but typically the statements
-are typed in by the user following prompts.
-Here is an example of an interactive-mode tarantool client session:
-
-<programlisting>

-Insert OK, 1 rows affected

+Square brackets <code>[</code> and <code>]</code> enclose optional syntax.
+Three dots in a row <code>...</code> mean the preceding tokens may be repeated.

+Depending how one combines the tarantool client's options, there are in effect three modes of operation:
+<quote>interactive</quote>, <quote>print and play</quote>, or <quote>replication</quote> mode.
+</para>
+<para>
+In <emphasis>interactive</emphasis> mode, one types statements and gets results.
+One can specify a statement file when starting
+(<code>tarantool < file_name</code>)
+or one can specify a statement file with the LOADFILE statement:
+(<code>LOADFILE file_name</code>), but typically the statements
+are typed in by the user following prompts.
+Here is an example of an interactive-mode tarantool client session:
+
+<programlisting>
+<prompt>$ </prompt>tarantool
+localhost> <userinput>INSERT INTO t0 VALUES ('X-1',100)</userinput>
+Insert OK, 1 rows affected
+localhost> <userinput>INSERT INTO t0 VALUES ('X-2',200,'On Order')</userinput>

+</para>
+<para>
+In <emphasis>print and play</emphasis> mode,
+one uses --cat and --play and --from and --to and --space options
+to print write-ahead-log contents, or to send write-ahead-log
+contents to the server.
+Here is an example of a print-and-play-mode tarantool client session:
+<programlisting>
