+# ==== Purpose ====
+#
+# Set up replication on several servers in a specified topology.
+#
+# By default, this script does the following:
+#  - Creates the connections server_1, server_2, ..., server_N.
+#  - Calls RESET MASTER, RESET SLAVE, USE test, CHANGE MASTER, START SLAVE.
+#  - Sets the connection to server_1 before exiting.
+# With $rpl_check_server_ids parameter, the script does the following:
+#  - Verifies that @@server_id of all servers are different.
+#
+# ==== Usage ====
+#
+# 1. If you are going to use more than two servers, create
+#    rpl_test.cnf with the following contents:
+#
+#    !include ../my.cnf
+#    [mysqld.1]
+#    log-slave-updates
+#    [mysqld.2]
+#    log-slave-updates
+#    ...
+#    [mysqld.N]
+#    log-slave-updates
+#
+#    [ENV]
+#    SERVER_MYPORT_3= @mysqld.3.port
+#    SERVER_MYPORT_4= @mysqld.4.port
+#    SERVER_MYPORT_5= @mysqld.5.port
+#    ...
+#    SERVER_MYPORT_N= @mysqld.N.port
+#
+#    (It is allowed, but not required, to configure SERVER_MYPORT_1
+#    and SERVER_MYPORT_2 too. If these variables are not set, the
+#    variables MASTER_MYPORT and SLAVE_MYPORT are used instead.
+#    These variables are configured in the rpl_1slave_base.cnf,
+#    that is used in the default my.cnf, which is used by the rpl suite.)
+#
+# 2. Execute the following near the top of the test:
+#
+#    [--let $rpl_server_count= 7]
+#    --let $rpl_topology= 1->2->3->1->4, 2->5, 6->7
+#    [--let $rpl_check_server_ids= 1]
+#    [--let $rpl_skip_change_master= 1]
+#    [--let $rpl_skip_start_slave= 1]
+#    [--let $rpl_skip_reset_master_and_slave= 1]
+#    [--let $rpl_debug= 1]
+#    [--let $slave_timeout= NUMBER]
+#    --source include/rpl_init.inc
+#
+#    Parameters:
+#
+#    $rpl_server_count
+#      The number of servers to configure.  If this is not set, the largest
+#      number in $rpl_topology will be used.
+#
+#    $rpl_topology
+#      A comma-separated list of replication chain
+#      specifications. Each replication chain specification has the
+#      form S1->S2->...->Sn, where 1 <= S1,...Sn <= $rpl_server_count.
+#      This file will configure S(i+1) to be a slave of S(i).  If you
+#      want to specify the empty topology (no server replicates at
+#      all), you have to set $rpl_topology=none.
+#
+#    $rpl_check_server_ids
+#      If $rpl_check_server_ids is set, this script checks that the
+#      @@server_id of all servers are different. This is normally
+#      guaranteed by mtr, so it is only useful for debugging.
+#
+#    $rpl_skip_reset_master_and_slave
+#      By default, this script issues RESET MASTER and RESET SLAVE
+#      before CHANGE MASTER and START SLAVE.  RESET MASTER and RESET
+#      SLAVE are suppressed if $rpl_skip_reset_master_and_slave is
+#      set.
+#      Also see $rpl_server_skip_log_bin.
+#
+#    $rpl_skip_change_master
+#      By default, this script issues CHANGE MASTER so that all slaves
+#      are ready to run as specified by $rpl_topology. CHANGE MASTER
+#      is suppressed if $rpl_skip_change_master is set.
+#
+#    $rpl_skip_start_slave
+#      By default, this script issues START SLAVE on all slaves
+#      specified by $rpl_topology. START SLAVE is suppressed if
+#      $rpl_skip_change_master is set.
+#
+#    $rpl_debug
+#      By default, this script only outputs a static text that says
+#      that rpl_init.inc was invoked. If $rpl_debug is set, additional
+#      debug info is printed. The debug info may be nondeterministic,
+#      so no test case should be checked in with $rpl_debug set.
+#
+#    $slave_timeout
+#      Timeout used when waiting for the slave threads to start.
+#      See include/wait_for_slave_param.inc
+#
+#    $rpl_server_skip_log_bin
+#      When $rpl_skip_reset_master_and_slave is not set
+#      RESET MASTER does not report ER_FLUSH_MASTER_BINLOG_CLOSED
+#      on any server.
+#
