-Enables the zbus message bus library (``apps/system/zbus``, a port of the
-Zephyr zbus — see :doc:`its documentation
-</applications/system/zbus/index>`) with all observer types (listeners,
-subscribers, message subscribers, async listeners, ISR publisher and
-runtime observers), together with its example application::
-
-    nsh> zbus
-    zbus: publishing 5 messages to acc_chan
-    zbus:  listener: x=1 y=10 z=100
-    zbus:  subscriber: x=1 y=10 z=100
-    ...
-    zbus: done
-
-The cmocka test suite from ``apps/testing/zbus`` is also included and can
-be used to validate the whole zbus API on the board::
-
-    nsh> cmocka_zbus_test
-    [==========] tests: Running 16 test(s).
-    ...
-    [==========] tests: 16 test(s) run.
-    [  PASSED  ] 16 test(s).
