  Results file for Instance Manager daemon test.
mysql-test/r/im_life_cycle.result:
  Results file for Instance Manager life cycle test.
mysql-test/r/im_options_set.result:
  Results file for Instance Manager SET statement test.
mysql-test/r/im_options_unset.result:

mysql-test/r/im_utils.result:
  Results file for Instance Manager utils test.
mysql-test/t/im_daemon_life_cycle-im.opt:
  Options file for Instance Manager daemon test.
mysql-test/t/im_daemon_life_cycle.imtest:
  Instance Manager daemon test (mysqltestrun-part).
mysql-test/t/im_life_cycle.imtest:
  Instance Manager life cycle test.
mysql-test/t/im_options_set.imtest:
  Instance Manager SET statement test.
mysql-test/t/im_options_unset.imtest:

+
+SHOW INSTANCES;
+
+#
+# Check 'SHOW INSTANCE OPTIONS' command:
+#  - check that options of both offline and online instances are accessible;
+#  - since configuration of an mysqld-instance contains directories, we should
+#    completely ignore the second column (values) in order to make the test
+#    case produce the same results on different installations;
+#    TODO: ignore values of only directory-specific options.
