+%% This suite can no longer be executed standalone, i.e. it must be
+%% executed with common test. The reason is that ct_snmp is used
+%% instead of the snmp application directly. The suite requires a
+%% config file, otp_mibs_SUITE.cfg, found in the same directory as
+%% the suite.
+%%
+%% Execute with:
+%% > ct_run -suite otp_mibs_SUITE -config otp_mibs_SUITE.cfg
