+# This test verifies the options --sync-relay-log-info and --relay-log-recovery by
+# crashing the slave in two different situations:
+# (case-1) - Corrupt the relay log with changes which were not processed by
+# the SQL Thread and crashes it.
+# (case-2) - Corrupt the master.info with wrong coordinates and crashes it.
+#
+# Case 1:
+# 1 - Stops the SQL Thread
+# 2 - Inserts new records into the master.
+# 3 - Corrupts the relay-log.bin* which most likely has such changes.
+# 4 - Crashes the slave
+# 5 - Verifies if the slave is sync with the master which means that the information
+# loss was circumvented by the recovery process.
+#
+# Case 2:
+# 1 - Stops the SQL/IO Threads
+# 2 - Inserts new records into the master.
+# 3 - Corrupts the master.info with wrong coordinates.
+# 4 - Crashes the slave
+# 5 - Verifies if the slave is sync with the master which means that the information
+# loss was circumvented by the recovery process.
