+# ==== Purpose ====
+#
+# Setup replication from an existing relay log in the current
+# connection.
+#
+# ==== Usage ====
+#
+# Make sure the slave is not running and issue:
+#
+#   let $fake_relay_log= /path/to/fake-relay-log-file.000001
+#   source include/setup_fake_relay_log.inc;
+#   START SLAVE SQL_THREAD; # setup_fake_relay_log doesn't start slave
+#   ...
+#   source include/cleanup_fake_relay_log.inc
+#
+# You must run the server with --relay-log=FILE. You probably want to
+# run with --replicate-same-server-id too.
+#
+# ==== Implementation ====
+#
+# First makes a sanity check, ensuring that the slave threads are not
+# running.  Then copies the $fake_relay_log to RELAY_BIN-fake.000001,
+# where RELAY_BIN is the basename of the relay log, and updates
+# RELAY_BIN.index. Finally issues CHANGE MASTER so that it uses the
+# given files.
+#
+# ==== Side effects ====
+#
+# Creates a binlog file and a binlog index file, and sets
+# @@global.relay_log_purge=1. All this is restored when you call
+# cleanup_fake_relay_log.inc.
+
